Abstract

The research on vegetative breeding of jack fruit has been conducted through grafting method, aiming at finding out the compatibility of lower cultivar resisting to drought stress with the jack fruit entries of pre-eminent varieties originally from central Sulawesi. Generally, the results of the research indicated that all entries except those grafted with the root stock BK-3 and TL-5 could only survive for 2 weeks leaving only their dead scions.  The latter appeared to be compatible with the Palupi entries as they were still able to live and grew until this research ended

Abstract

ABSTRACTThe aims of this research on Reutealis trisperma seed were to know 1) seed harvest maturity level based on physiological and biochemical changes; and 2) seed recalcitrancy based on critical moisture content and storability in two storage temperatures. The research was conducted at Leuwikopo Seed Science and Technology Laboratory, from February 2012 to January 2013. There were three experiments, i.e. I. Effect of seed maturity level on seed viability and vigor (randomized completely block design, 3 seed maturity level, 3 replications); II. Determination of seed critical moisture content, used two methods, i.e. 1) fan drying and 2) air drying (completely randomized design in each drying methods, 3 replications); III. Effect of temperature and period of storage on seed viability and vigor (nested design, first factor was 2 storage temperature and the second factor was 7 storage periods, 3 replications). The result showed that seed physiological maturity achieved in 28 weeks after flowering with morphological criteria were brownish fruit, soft fruit exocarp, brown seed testa; physiological criteria was germination percentage 76-80% and biochemical criteria was carotenoid content 0.62 µmol(g FW)-1. Carotenoid content can be used as biochemical indicator to determine fruit maturity and significantly correlated with moisture content, seed dry weight and germination percentage. Critical moisture content were 8.2-10.9%. These data suggested that seeds could be classified as intermediate. R. trisperma  seeds could be stored for three weeks in temperature 19-28 oC and RH 50-70%, with 12% moisture content used polypropilen plastic bag Keywords: carotenoid, critical moisture content, desiccation, Reutealis trisperma

Abstract

The research was aimed at studying the effects of seed deoperculation treatment and germination substrate to enhance viability of sugar palm seed. This research was conducted from February until August 2006 at Seed Science and Technology Laboratory and Turfgrass area. Randomized block design with 2 factors was used in this research. The first factor consisted of five treatments namely: control, without seed treatment (P0), deoperculation with sand paper precisely on the embryo position (PI), deoperculated seed and heating in the incubator at 40oC for 5 minutes (P2), deoperculated seed and soaking in the potassium nitrate (KNO3 0.5%) for 36 hours (P3) and deoperculated seed, soaking in the potassium nitrate for 36 hours and heating in the incubator at 40oC for 5 minutes (P4). The second factor substrate used for germination consisted of five types, i.e., sand (M1), soil and compost mixed, each in equal (1:1) portions by weight (w/w) (M2), saw dust (M3), cocopeat (M4) and paddy charcoal (M5). The result showed that seed deoperculation gave very significant effect to enhance seed viability. The interaction between seed treatment and substrate significantly influenced on potential growth, germination percentage, speed of germination, the length of embryonic axis and the length of root. The highest potential growth of 96.67% was obtained from deoperculated seed and heating in the incubator at 40oC for five minutes and germinated in sand, whereas highest germination percentage of 88.33% was reached by deoperculated seed and germinated in sand. Sand (M1), cocopeat (M4) and paddy charcoal (M5) were suitable for germination substrate of sugar palm seed.   Key words:  Sugar palm seed, seed viability, deoperculation, cocopeat, paddy charcoal.

Abstract

The objective of this experiment was to study the influence of post-harvest storage and storage period to seed viability. The research was conducted in the Laboratory of Seed Science and Technology and the green house at Leuwikopo IPB Darmaga, from February until August 2007. The experiment used split-plot design with three replications. The main plot was seven periods of storage: 0, 3, 6, 9, 12, 15, and 18 weeks. The sub plot was the period of post-harvest maturation storage (use the fruits with 30-40% yellow coloured): 0, 2, 4, 6 days post-harvest storage, and control fruits that ripe on the tree (with 80-90% yellow coloured). The control fruits have the best seed viability and vigor. Viability of seed from fruits with 0, 2 and 6 days post-harvest storage was significantly less than that of control. Seed from four days post-harvest storage have same viability as control. Post-harvest storage can improve physiological seed quality on the seed that must be harvested before the time of physiological maturity, especially four days post-harvest storage

Abstract

Provision of jatropha (Jatropha curcas) seeds along with providing high yielding varieties, is needed to ensure high seed quality. This experiment aimed to observe the pattern of jatropha seed treatment, namely the effect of fruit maturity, fruit extraction methods, seed drying, seed packaging type, and storage duration of seed on the seeds quality. The experiment was conducted from June to November 2011. Jatropha plants used as sources of seeds were obtained from jatropha plantations PT Indocement Tunggal, Tbk, Citeureup, Bogor. Seed handling experiments was conducted at the Seed Technology Laboratory, IPB. The results showed that the level of fruit maturity did not significantly affect the moisture content of seeds, the seeds germination and speed of seedlings growth, but it was significantly affect the dry weight of seed, dry weight of normal seedling, and oil content. The fruit extraction affected the time of peeling, duration of seed sortage, amount of impurities and the extent of seed damage, but it was not significantly affect the seed germination. The seed drying did not significantly affect the seed germination. The length of storage that can retain up to 51% seed germination during 3 months storage was the seed that have been stored in earthen barrel.

Abstract

Improved seed longevity by seed drying and application of  phenolic compound as natural antioxidant is the topic of this research. In many cases the sensitivity of papaya seed to drying is being the limit factor because of desiccation injury or induced dormancy. There is phenolic compound on the sarcotesta surrounding papaya seed which may act either as antioxidant or as germination inhibitor. The effect of sarcotesta and seed drying on viabillity and dormancy was studied. The experiment was conducted in July - October 2004, located at Bogor Agricultural University, used papaya seed (IPB-1) which harvested from Pusat Kajian Buah Tropika (PKBT) farm in Bogor. In the last study, seed was dried in the absence and presence of sarcotesta until 11-12% and 6-7% moisture content (mc). After drying, seed viability was measured by tetrazolium test.  The hardness of seed was also measured using penetrometer.  Seed germination was tested by (1) soaking on 10% KNO3, (2) scarification on water using  electrical stirrer, (3) soaking on 10% KNO3  with scarification using electrical stirrer, (4) scarification on the  hot water (50oC) followed by soaking on 10% KNO3.   In the absence of sarcotesta, the viability of 6-7% mc seed was as high as 11-12% mc seed. There was neither viability reduction nor induced dormancy. Whereas in the presence of sarcotesta, there was also no viability reduction but the dormancy was induced. The dormancy of seed with 11-12% mc was longer than seed with 6-7% mc. Scanning electron microscopy images showed that sarcotesta was removed by cleaning treatment before drying. On the contrary, sarcotesta was not completely removed from the seed and became more impermeable when cleaning was done after drying.This research can not suggest the most effective  pre-treatment to break the dormancy. The mechanism of the dormancy is discused.   Key words: Carica papaya L., seed drying, sarcotesta, seed viability, seed dormancy

Abstract

The objectives of this experiment were to evaluate the possibility of using quick lime for extraction of mangosteen seed and the effects on its viability; The experiment was done in Seed Science and Technology Laboratory, Greenhouse, Bogor Agriculture University from November 1997 until February 1998. The materials were taken from smallholder plantation in Jasinga, Bogor. The treatments were arranged factorial in a group randomized block design with two factors. The first factor was 6 levels of quick lime concentration (K) : 0 g/l, 10 g/l, 15 g/l, 20 g/l, 25 g/l, 30 g/l and the second factor was 4 levels of soak periods: 0 minute, 10 minutes, 20 minutes, 30 minutes. The experiments had 24 treatments combination with 4 replicates so there were 72 experiment units. The data show that seed extraction using quick lime gave statistically significant different results compared with seed extraction without using quick lime and so the soak periods compared with no soak. Interaction between 20 g/l quick lime concentration and 30 minutes soak period gave the best seed emergence (96 %). 20 g/l quick lime concentration save higher vigour than other concentration as measured from its speed of germination, spontaneous growth, and root length. The soak periods increased seed moisture content 30 minutes soak period resulted higher viability and vigour than other soak periods as measured from its normal seed dry weigh, spontaneous growth, epycotyl length and root length.
