Abstract

Oilly seeds, such as those of sunflower (Helianthus annuus L.), have short storability (3-4 months in room condition) due to oxidative stress during storage. The objective of this research was to determine whether prestorage seed invigoration by antioxidants, could improve storability of sunflower seeds. The research was performed using fresh harvested seeds. Prestorage seed invigorations were conducted by matriconditioning with water or antioxidants solution i.e. 4.17% curcumin or 100 and 150 ppm ascorbic acid. The seeds were stored for four months at room condition (28-29 oC and 62-79% relative humidity). Observations were conducted monthly. Experiment was arranged in split plot design. The result showed that all prestorage seed invigoration treatments were not effective to enhance storability of sunflower seeds compared to control. Inefficiency exogenous antioxidants was probably due to highly endogenous antioxidants activity during storage. This was indicated by the slow deterioration rate of control seeds, or due to high concentration of curcumin which was actually potential to enhance storability of sunflower seeds. It is suggested that presowing treatment and midstorage treatment will enhance storability of sunflower seeds.Back

Abstract

The research aims to find out the effect of seed scarification and germination substrat to seed viability and seedling vigor of aren. The Experiment applied a group random design (RAK) with factorial style consiting of two factors. The first factor are scarification treatment:S0=without scarification, S1=scarification+trcatment 40 oC, S2=scarification+KN03 0.5%, soaked for 36 hours+tempcrature 40oC, the second factor arc germination substrat: M0=sand, M1=rice coal, M2=cocopith, M3=soil from palm tree+organic materil (1:1), M4=M3+fertilizer NPK (1 g per kg media). The highest seed germination was found in the scarification+KN03 0.5%, soaked for 36 hours+ temperature 40 oC which growing on media of palm oil soil+organic fertilizer (1:1)+fertilizer NPK (1g per kg media) that 83.33-86.67% and germinating speed 0.85-1.04% ctmal. There treatment also effected on seedling vigor normal vigours germination indicated by dry content weight and hypotctic vigor index. Keywords: aren, scarification, germination substrat

Abstract

This study aimed to obtain genotypes of local jatropha has the potential to be developed through the characterization based on quantitative and qualitative characters. The experiment was conducted in August 2009-April 2010 took place at the experimental PT. Indocement, Citereup-Bogor. Materials used jatropha cuttings from 10 genotypes (Banten, Medan, Biak, IP-2P, Bengkulu, Sukabumi, Bali, Sulawesi, Bogor, and Lombok). The observed character is the character of quantitative and qualitative. The results showed 10 genotypes Jatropha tested has the color green of young stems and old stems green color gray. The color of shoots is green, and coloor of old leaf is dark green.The color of leaf bones is purple and green, leaf textureis coarse, and leaves bones clearly visible. Genotype that has hermaphrodite flowers are Banten, Biak, Bengkulu, and Sukabumi. The best genotype was Banten with leaf number 74, branch height 48 em, number of panicles 1 plant 12.2, the number of fruits I plant 110.5, wet seed weight I plant 288.7 g, and dry seed weight I plant 193.8 g. Variables wet seed weight I plant is a selection of characters that can be used to increase the yield of dry seed weight 1 plant. Another character that indirectly affect significantly positive effect on dry seed weight of stem diameter, leaf number, number of fruits per panicle, and number of fruit I plant. Selection on vegetative characters can not be used as selection criteria.

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

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

The research aim was to find out the effect of seed scarification and germination substrate upon seed viability and seedling vigor of aren.  The research applied a randomized block design with factorial pattern consisting of two factors.  The first factor was scarification treatment: without scarification, scarification at 400C, scarification at 400C and soaked in 0.5% KNO3 solution for 36 hours.  The second factor was germination substrate:  sand, rice hull coal, cocopith, mixture of soil taken from natural palm growth area and organic material at a ratio 1:1, and mixture of 1 g NPK fertilizer with 1 kg soil taken from palm tree forest area and organic material media.  The greatest seed germination of 83.33–86.67% with germinating speed of 0.85-1.04 %etmal was found in the scarification at 400C soaking in 0.5% KNO3 solution for 36 hours and soil organic and matter treatment. This treatment also resulted in normal vigorous seed indicated by higher dry content weight and hypothetic vigor index than any other treatments.
