Abstract

Effects of water stress on plant growth and production of cashewTo complete the characteristic tests of prospective numbers of cashew (Anacardium occidentale L). research on the production stability and envi¬ ronmental stress tolerance were conducted. The objectives of the research were to study the effects of the water stress on the growth performance, inflorescent formation, production and quality of cashew. The research activi¬ ties wee caried out at Cimanggu Research Insulation from Apil 1995 to March 1998. The research used factorial randomized block design with 3 replications and 4 plants per pot. The treatments tested were wateing intervals (A) of 2, 4. 8. and 12 days with 9 mm deep of water for each treatments Prospective numbers of cashew (N) namely Pecangakan. Jepara F2-10. Balak¬ risnan B-02. and Silanka S-21. The results obtained 13 months ater gratings or 11 months ater the application showed that water stress and prospective numbers significantly affected the vegetative growth of the plants namely plant height, primary branch number, secondary branch numbers and canopy diameter. Amongst the prospective numbers, Balakrisnan B-02 had lower growth rate compared with Pecangakan. Jepara F2-I0, and Silanka S-21. Water stress significantly affected the formation of inflorescence, which tended to decrease along with the increase of water stress. On the same level of water stress, the inflorenscent formation of Jepara F2-10 was more domi¬ nant than the other numbers. However the proportion of male flowers, hermaprodite, and the ratio ofhermaprodite flowers to total number of flowers wee not significantly affected by water stress. The difference of inflorescent formation of prospective numbers was significant on the formation of the male flowers only, the highest was Srilanka S-21 and the lowest was Jepara F2- 10. The water stress showed significant effect on the number of the pods per tree, production and the protein content of the cashew nuts. The number of pods per tree and the production tended to decrease along with the increase of water stress, while the protein content of the cashew nut tend to increase along with the water stress incease The number of pods and production per tree were highest on Balakisnan B-02 followed by Pecangakan. Jepara F2-10 and Silanka S-21. espectively, where as the highest protein content of Ihe cashew kernel was on Balakrisnan B-02.

Thereutalis oil is toxic, therefore it is inedible due to about 50% α-eleostearatacid content in the oil. As a potential plant, its information in more detail isneeded including the DNA analysis. There are many techniques to conductDNA isolation depending on kind of plants, plant organ, or plant tissuethat will be analyzed. The aim of this experiment was to find theeffectiveness and efficiency techniques of DNA isolation and purification,so they can reduce cost and time while working in the laboratory. Theexperiment was conducted at Molecular Biology Laboratory of IndonesianCenter for Agricultural Biotechnology and Genetic Resources Researchand Development (BB BIOGEN), Bogor from July to September 2010.Young leaves of reutelis used as genetic materials were taken fromgermplasms collection at Pakuwon Experimental Station of IndonesianSpice and Industrial Crops Research Institute (ISICRI), Sukabumi. Whilesome chemicals were used as the other material. The activities were asfollows : DNA extraction and purification, measurement of DNAconcentration, and amplification of DNA. Deletion of resistor enzyme-polysacharide, especially for perennial plant. DNA isolation can be doneby breaking down of cell wall, cell membrane, and nuclear membrane. Theresults showed that conscientiousness of DNA isolation and purificationdenoted an important step to obtain clean and contaminant free of DNA, sothe banding patterns were clear. In this technique did not usepolypinilpolypirolidone (PVPP) and mercapto-ethanol such as antioxidant,liquid nitrogen, neither over night storage of leaf extraction before used forpurification which is often used for perennial plant. In addition the resultsshowed that band pattern of DNA was very thick and clear, therefore thistechnique can be applied for DNA isolation on Reutalis trisperma.Key words: Reutalis trisperma, optimization, isolation, purification, DNA

Abstract

ABSTRAKHingga kini teknik perakitan varietas kapas tahan hama masihdilakukan secara konvensional berdasarkan beberapa karakter morfologitanaman, seperti: bulu daun, daun okra, braktea berpilin, nektar, dangosipol tinggi. Karakter-karakter ini diketahui erat hubungannya denganketahanan terhadap hama, khususnya H. armigera. Berkaitan denganserangan H. armigera pada buah, diduga ada bagian-bagian buah kapasyang berkontribusi secara langsung pada serangan hama ini, misalnyabraktea buah. Namun demikian, besarnya pengaruh braktea terhadapkerusakan buah kapas perlu dipelajari dalam upaya meminimalkankerusakan. Penelitian ini bertujuan untuk mengetahui pengaruh ukuranbraktea terhadap tingkat kerusakan buah oleh H. armigera pada beberapaaksesi kapas. Penelitian dilaksanakan di Kebun Percobaan Balai PenelitianTanaman Tembakau dan Serat, di Asembagus, Situbondo, Jawa Timurmulai bulan Januari hingga Desember 2006. Sebanyak 18 aksesi dari 50aksesi kapas dengan berbagai variasi ukuran braktea digunakan sebagaiperlakuan. Setiap perlakuan (aksesi) disusun dalam rancangan acakkelompok (RAK), dengan tiga kali ulangan. Lima tanaman kapas darimasing-masing aksesi ditentukan secara acak, dan sebanyak 5 buah kapasmuda (diameter ± 4 cm) dipetik dari masing-masing tanaman sampel,kemudian dibawa ke laboratorium untuk diukur luas braktea dan buahnya.Selain itu dilakukan pula pengamatan kerusakan buah dan hasil kapasberbiji di lapang. Hasil penelitian menunjukkan bahwa ukuran brakteaberkorelasi positif dengan tingkat kerusakan buah (R 2 = 0,9014), sehinggabraktea berukuran besar dan lebar serta menutupi buah secara totalberpotensi mengalami kerusakan akibat serangan H. armigera lebih tinggidibanding braktea berukuran kecil dan sempit. Ukuran panjang dan lebarbraktea pada 18 aksesi kapas bervariasi antar aksesi dan masing-masingberkorelasi positif dengan luas (R 2 = 0,876; R 2 = 0,894). Hasil penelitianini dapat dimanfaatkan dalam merakit varietas tahan hama, dankombinasinya dengan karakter-karakter morfologi kapas yang sudah adauntuk menghasilkan varietas kapas baru dengan tingkat ketahanan yanglebih tinggi terhadap hama penggerek buah H. armigera.Katakunci : Braktea, Helicoverpa armigera, aksesi kapas, karaktermorfologi.ABSTRACTEffects of bract size of several cotton accessions toAmerican bollworm injury levelConventional  method  by  crossing  technique  based  onmorphological characters of plant is now still used in providing resistantvarieties of cotton against insect bollworms. A number of geneticcharacters are now available and have been studying for their assosiationwith insect pests resistance such as hairiness, okra leaf, frego bract,nectariless, and high gossypol. Regarding to boll damage by H. armigera,it can be mentioned that there are many other morphological characters ofcotton attributable to bollworm damage, such as floral bract. As a part ofboll, it is estimated that bracts assosiated with bollworm attacked due totheir larger size compared with boll size. Objective of the study was to findout the effect of bract size in relation to bollworm damage on cottonaccessions. The study was conducted at Experimental Station ofIndonesian Tobacco and Fiber Crops Research Institute in Asembagus,Situbondo, East Java from January to December 2006. Eighteen of fiftycotton accessions were used as treatment and they were arranged inRandomized Block Design (RBD) with three replications. Five randomlycotton plants from each accession and five young bolls were sampledfrom the selected plant with about 4 cm of diameter were brought in thelaboratory to collect information on bract and boll sizes. Bollwormdamage was determined by counting the damaged bolls in the field as wellas the seed cotton yield. Result showed that bract size was positivelycorrelated with boll damage (R 2 = 0.9014). Higher damaged bolls occuredon bolls which is covered completely by bracts. There is variation betweenlength and wide size of bracts among cotton accessions and both showedpositive correlation to bract area (R 2 = 0.876; R 2 = 0.894). Based on thisstudy, higher resistance of cotton variety against H. armigera willpossiblly be provided through combination between bract size and anyother morphological characters of cotton.Key words : Floral bract, Helicoverpa armigera, cotton accession,morphological character

Abstract

Strong opinions have been expressed toward oil palm plantation industry in Indonesia, and these opinions portray that oil palm plantation development in Indonesia has caused the destruction of the environment. One of the efforts currently undertaken by the Indonesian government to ensure the sustainability of the palm oil industry is establishing sustainability standard called the Indonesian Sustainable Palm Oil (ISPO) which is mandatory. ISPO is "guidance" for sustainable oil palm development as well as a commitment based on the laws and regulations aplication of some licenses in Indonesia. The purpose of this study was to determine the capability of oil palm plantation companies in the regional to meet the standards of the Indonesian Sustainable Palm Oil (ISPO) and to identify the problems faced in achieving these standards. This research was conducted in East Kalimantan province on the period June 2012-May 2013. Evaluation of the capability of the companies to achieve the ISPO standards was performed by the audit method, assessment results of all parameters that had been established in accordance with the Principles, Criteria and Indicators in the provision of ISPO which were assessed in a percent unit. The research results showed that the capability of the plantation companies in East Kalimantan in meeting the ISPO standards reached 79,14%, and this capability can be improved up to 100% by increasing efforts to comply with the principles, criteria and indicators that are still not in accordance with the provisions of ISPO are as follows: 1). Licence system and plantation management, 2). Aplication guidance cultivation technics and processing palm fruit, 3). Management and monitoring invironment, 4). Resposibility to workers, and 5). Social resposibility and community. The determantion factor performance on ISPO standard is the commitment of plantation company as a business stakeholder that supported by capable human resources to create the sustainable plantation development and also the goverment action in charge as the regulator in supervising the policy that has been set. Socialization and training about principles and criteria ISPO standard to plantation company needs soon and more intensively done by the government association with ISPO commission to accelerate the application of the ISPO. Socialization and training also are required in order to overcome the constraints in attainment of principles and criteria of the Indonesian Sustainable Palm Oil standard, because of the mentioned efforts are the part of success factors to apply the ISPO.Keyword: ISPO, Management, Palm Oil, Plantations, Sustainable.

Adapuntujuan persilangan tersebut adalah untuk meningkatkan produktivitas danmutu serat varietas kapas nasional Indonesia. Program perbaikan varietasini menggunakan pendekatan seleksi pedigree pada F3, dan dilanjutkandengan seleksi galur pada generasi F5 dan selanjutnya. Pada kegiatanseleksi galur tahun 2004-2005 di Kebun Percobaan Asembagus, dari 22genotipe generasi F4 yang diseleksi dengan kriteria seleksi produktivitas >3 ton kapas berbiji/ha telah dihasilkan 23 galur harapan. Pada generasi F6dilakukan uji daya hasil dari 23 galur tersebut. Dari pengujian daya hasilgalur-galur tersebut pada tahun 2006, telah dihasilkan enam galur harapanyang memiliki tingkat produktivitas secara statistika tidak berbeda denganatau lebih tinggi dari Kanesia 8 dengan panjang serat > 1,16 inch, kekuatanserat > 30,77 g/tex, dan kehalusan serat antara 3,5 – 4,5 mic, yaitu99004/5, 99005/9, 99013/5, 99023/5, 99023/7, dan 99023/8. Galur-galurtersebut selanjutnya akan diuji secara multilokasi untuk menilai stabilitasekspresi genetiknya di beberapa wilayah pengembangan kapas.Kata kunci : Gossypium hirsutum, kapas, produktivitas, mutu seratABSTRACTVarietal Improvement for Increase of Productivity andQuality of Cotton Fiber Cotton breeding conducted since 1999 involving 11 varieties asfemale parent, and five varieties as male parents has resulted in 22crossing sets. The aim was to improve productivity level as well as fiberquality of national cotton varieties of Indonesia. The breeding approachwas accomplished by pedigree selection on F3 generation, which was thencontinued with line selection from F5 generation. From the line selectionactivity carried out at Asembagus Experimental Station during 2004-2005,out of 22 genotypes selected at the F4 generation based on productivitylevel of > 3 ton seed cotton/ha as selection criteria, 23 promising lines hadbeen selected which were then tested in a yield potential test. From theyield potential test conducted in 2006, six promising lines had beenselected whose productivity levels were statistically not different from orhigher than Kanesia 8 with fiber length of >1.16 inch, fiber strength>30.77 g/tex, and fiber fineness 3.5-4.5 mic. Those promising lines wouldthen be tested in multilocation trials to evaluate the stability of theirgenetic expression in several cotton development areas.Key words : Gossypium hirsutum, cotton, productivity, fiber properties
