Abstract

Penelitian untuk mengetahui pengaruh kerusakan buah semu jambu mete terhadap viabilitas dan pertumbuhan benih jambu mete telah dilakukan mulai bulan Januari  sampai  Desember 2009 di Kebun Percobaan Cikampek, Jawa. Bahan yang digunakan adalah benih jambu mete dari Desa Watukawula, Kecamatan Wewewa, Kabupaten Sumba Barat Daya, Propinsi Nusa Tenggara Timur. Percobaan disusun dengan dua taraf perlakuan yaitu benih jambu mete yang berasal dari buah semu normal beraroma harum dan benih yang berasal dari buah semu rusak mengering. Jumlah sampel yang digunakan untuk mengetahui perkecambahan benih dan bobot serta ukuran benih sebanyak 60 butir benih setiap perlakuan, sedangkan untuk mengetahui pertumbuhan bibit digunakan 30 polybag pada setiap perlakuan. Analisis data dilakukan dengan uji t pada taraf 5% secara  berpasangan. Hasil penelitian menunjukkan bahwa kerusakan buah semu berpengaruh terhadap bobot, tebal, dan viabilitas benih serta pertumbuhan tinggi bibit, sedangkan panjang dan lebar benih, serta diameter batang dan jumlah daun tidak berpengaruh. Bobot dan viabilitas benih jambu mete asal buah semu normal 6.7 g dan 77.7 %, sedang asal buah semu rusak 4.7 g dan  51.0 %.Viability of seeds taken from abnormal cashew applesABSTRACTViability of seeds taken from abnormal cashew apples. The experiment was carried out from January  to December 2009 to know about effect damage of cashew apple to the seed viability and growth of cashew seedling on Cikampek Experimental Station, West Java. Material was used cashew seed from Watukawula village, Wewewa Sub District, Southwest Sumba district, province of Nusa Tenggara Barat. The experiment was arranged with observation on two treatment i.e : Seed was harvested  with normal cashew apple and seed was harvested with damaged cashew apples. Number of sample was used to know the seed viability is 60 seeds for each treatment, further more to know the growth of cashew seedling was used 30 polybag per treatment. Analysis was used t-Student test with 5% level paired. Result of this experiment showed that the good seed viability was seed from normal compare with damaged cashew apples, 77.7% and 51.0% respectively. The best seed quality and viability was seed from normal cashew apples

Abstract

The research was to obtain proper length of upper stem to the success rate of grafting and grwoth of the seedling cashew nut plants have been conducted in the Garden Experiments Cikampek, Karawang regency, West Java. Soil types was rocky laterite andesite, type C climate and altitude of 50 meters above sea level. The research was conducted in August 2009 until April 2010. While the materials used cashew seed type B 02 for both rootstock and to the upper stem. Grafting was done after 3 months old seedlings with seedlings about 60 cm high and 0.6 cm diameter stems of seedlings. Experiments prepared following the randomized block design was repeated three times that consisting of 10 plants. The treatments were tested namely long scion 10, 15 and 20 cm. Plants grew in polybags with size 15 x 25 cm. The indicators were observed covering the base of the cuttings scion diameter, cutting the base color of entres, the percentage of shoots continued success, increased plant height, leaf number and stem diameter of the seed.The results showed that the length of entres effect on continued success grafting  of seedling cashew. Scion length was 20 cm which gave the highest grafting success is as much as 78%.

Abstract

Estimation of genetic parameter of cashew are important as the basis information for the next breeding programm. The research was conducted at Cikampek Experiment Station at altitude about 50 m above sea level, Laterite type of soil and C type of climate, beginning from January 2009 until January 2011. The objectives of this research are to: (1) estimate the genetic parameters which include the coefficient of genetic variability, heritability, and genetic advances, and (2) analyze the genotypic and phenotypic correlations between vegetative characters of cashew from Sumba Barat Daya populations (SBD). Randomized Complete Block Design with eight treatments of accession numbers of cashew with three replications was used in this study. Variables measured were the components of vegetative growth i.e. : height of plant (TT), stem diameter (DB), number of branches (JC), canopy width of U-S (LTUS), canopy width of B-T (LTBT), height of the first branching (TPP), length of leaves (PD), width of leaves (LD), and ratio of width and length of leaves (RLPD). Results showed that: (1) in general the genetic variability of vegetative characters of cashew in SBD populations were narrow, except number of branch and height of first branch characters. The improvement of number of branch characters has a high probability and success by breeding programm;  and (2) genetically number of branch characters has a positive correlation with height of plant, canopy width of U-S, and canopy width of B-T, but a negative correlation with height of first branch characters.
