Abstract

Java kenanga or kenanga (Cananga odorata f. macrophylla) is a tropical and sub-tropical tree species that grows naturally in Indonesia and produces essential oil. This species has been cultivated in the past by community in Indonesia, mainly on their yard. The population of kenanga has decreased significantly, but in Blitar district the community is still doing cultivating the species although in a small scale. The purpose of this research is to observe the cultivation efforts by the community and also kenanga flower production in Blitar district. This research was conducted by interviewing farmers and observation of kenanga trees in the field. The results showed that cultivation efforts being made to improve the production of kenanga flower is by pruning, fertilizing, flowering routine and retrieval or emoval of kenanga fruit. The average kananga flower production reached 381 kg / year / tree in the age group above 11 years. Factors that affect flower production were tree age (years), total tree height (m), diameter at breast height (cm) and the width tree canopy (m2). The most significant factors affecting flower production were tree diameter and width of tree canopy. Cultivation efforts being made to improve the production of kenanga flower is by pruning, fertilizing, flowering routine and retrieval or removal of kenanga fruit.

Abstract

The presence of Pericopsis mooniana (Thw.) Thw. in nature is endangered. Meanwhile, Pericopsis mooniana plants have its obstacles in generative propagation because the seeds have mechanical dormancy. Studies carried out to: (1) observe the morphology of pods, seeds and sprouts of Pericopsis mooniana; (2) determine the physical quality of Pericopsis mooniana seeds, and (3) analyze the proper dormancy breaking treatment for Pericopsis mooniana seeds. Research is conducted in laboratories and in greenhouses. The physical quality of the seeds measured was the weight of 1,000 seeds and the moisture content. The treatment for breaking the dormancy of the Pericopsis mooniana seeds were control, scarification of the seeds using nail clippers and soaking in hot to cold water for 48 hours. Morphologically, the fruit of Pericopsis mooniana is pod-shaped, with orange seeds, oval-shaped and curved edges. Pericopsis mooniana sprouts include in the epigeal type. In 1 kg of weight there are ± 4,000 Pericopsis mooniana seeds, with the post harvest seed moisture content amounting to 7.62%. The dormancy breaking treatment of Pericopsis mooniana seeds increased seeds germination by 60% compared to controls. The scarification of Pericopsis mooniana seeds using nail clippers for breaking mechanical dormancy is the best treatment because it can increase the number of seeds germinating in a short time and simultaneously. Key words: breaking seed dormancy, morphology, Pericopsis mooniana, physical quality, seed scarificatio

Abstract

The dormancy of Ketapang kencana seeds can be removed by using pre-treatment in order to breaking dormancy of seeds. The aim of this study was to analyze the effect of pre-treatment for breaking dormancy of seeds, and the seed size on the Ketapang kencana seed germination. Ketapang kencana seeds that have been extracted are classified into 3 sizes, such as: large, medium and small. After that, the seeds were treated with dormancy breaking, such as: (1) control, (2) seeds cutting, (3) seeds sanding, (4) seeds soaking in H2SO4 solution, (5) seeds soaking in hot water (temperature ± 80 oC) for 10 minutes, (6) seeds soaking in water for 12 hours, and (7) seeds soaking in water for 72 hours. The results showed that there were 3 pre-treatments of seeds dormancy breaking that could increase the seed germination, such as cutting the seeds on the endocarp, sanding the seeds on the endocarp, and soaking the seeds in the water for 12 hours. The pre-treatments of seeds dormancy breaking significantly affected the germination index, normal sprout growth (dry weight, height, root length), and the start of sprout growth. Ketapang kencana seed size affected the germination and the dry weight of normal sprouts. The large seeds (0.65–0.82 cm) had the highest germination and dry weight. In general, the pre-treatment of seeds dormancy breaking and the seed size increased the germination of Ketapang kencana seeds. Key words: maximum growth potential, seed germination, seed size, seed viability, seed vigour

Abstract

Improving the physical quality of kayu kuku seedlings can be done by applying endophytic bacteria and ec-enzymes. The aims of this study were to examine (1) the effect of inoculation of endophytic bacteria on the germination of kuku wood seeds, and (2) the effect of inoculation and application of eco-enzymes on the growth of kuku wood seedlings. The endophytic bacteria were isolated from the shoot of Shorea balangeran plant with the codes SBP 1, SBP 2, and SBP 19. Bacterial application was conducted on seeds and seedlings, while eco-enzyme application was only conducted on kayu kuku seedlings. The results of the research at the seed level showed that inoculation of the endophytic bacteria SBP 19 could accelerate the germination rate of kayu kuku seeds. At the seedling level, inoculation of endophytic bacteria SBP 1, SBP 2, SBP 19 and application of eco-enzymes had no significant effect on height, diameter, number of new leaves, total fresh weight and total dry weight of kayu kuku seedlings. The shoot root ratio of kayu kuku seedlings ranged from 2.66-5.04 and the seedlings quality index ranged from 0.41-0.93, indicating that the seedlings were ready to be transplanted into the field. In general, inoculation of endophytic bacteria had a significant effect on kayu kuku seed germination, but had not been able to increase the growth of kayu kuku seedlings during the 14 weeks of observation. Keywords: Pericopsis mooniana Thw., seed dormancy, seed germination, seedling quality index, shoot root ratio

Abstract

The plant species commonly used in Industrial Plantation Forests as raw material for pulp and paper is Eucalyptus pellita. One of the quality seeds of E. pellita is produced from superior clones by vegetative propagation, namely shoot cuttings. There are research results that show the propagation of certain clones has the highest Survival Rate when treated without using additional hormones. Therefore, it is necessary to conduct research on the propagation of E. pellita seed cuttings without using hormones. The results of the physiological analysis of E. pellita shoot cuttings showed that each parameter observed, namely IAA hormone content, C-organic, and N value, showed non-linear results with shoot age treatment. The results of measuring shoot length, number of nodes, and distance between nodes showed linear values with shoot age treatment. The results of observations of total Survival Rate, total roots and shoots showed that the 18 day shoot age treatment had the lowest value compared to other treatments. At the age of 2 weeks, it showed that the 21 day shoot age treatment had the fastest root growth ability compared to other treatments. Based on the results of height and diameter measurements at 12 weeks, it shows that 21 day old shoots have the best growth and Survival Rate so that they can be used as a basis for determining the age of shoots in the production of clone 148 seedlings on an operational scale.

Abstract

Penyimpanan benih dalam jangka waktu tertentu dapat memengaruhi viabilitas benih. Tujuan penelitian ini adalah menganalisis pengaruh lama penyimpanan benih terhadap viabilitas benih mindi. Metode yang digunakan adalah uji daya hantar listrik atau electrical conductivity (EC) terhadap air rendaman benih yang telah disimpan selama 0, 2, 4, 6, dan 8 bulan. Pengukuran nilai konduktivitas listrik dilakukan menggunakan alat conductivity meter. Hasil penelitian menunjukkan bahwa lama penyimpanan memengaruhi nilai EC benih mindi. Nilai EC terendah adalah 15,63 µS/cm pada penyimpanan 0 bulan dan nilai EC tertinggi adalah 31,87 µS/cm pada penyimpanan 8 bulan. Lama penyimpanan memiliki korelasi positif terhadap nilai EC sebesar 0,75. Nilai EC yang tinggi menunjukkan banyaknya perembesan cairan sel yang keluar dari benih sehingga menurunkan kapasitas perkecambahan benihnya. Nilai EC memiliki korelasi negatif terhadap viabilitas benih. Secara umum, semakin lama benih disimpan, maka viabilitas benih semakin menurun.

Abstract

Gmelina is a fast growing species that has high sufficient economy value and useful as medicinal plant. Propagation of gmelina by tissue culture has not been widely applied in Indonesia. This study aims to analize the effect of explant types and sterilization methods on the success of gmelina initiation. Treatments used in this study are explant types (apical shoot and leaf) and four sterilization methods (B1-B4) using detergent, tween 80, fungicide, bactericide, NaOCl, and HgCl2. All sterilization methods can produce 6‒19% sterile gmelina shoot culture, but has not succeded producing sterile gmelina leaf culture. Contamination by fungi and bacteria is the main cause of failed gmelina shoot and leaf culture initiation. In general, sterilization methods used in this study has succeeded in eliminating microbes on the explant’s surface, but has not succeeded in eliminating microbes inside the explant.
