Abstract

Viability of small seed is usually tested with top of paper method using paper substrate, but filter and straw papers commonly used for substrate have become more expensive and scarce recently. The aim of this study was to find an alternative paper substrate for seed viability testing using top of paper method. The study consist of 12 experiments using 12 species i.e. pak choy, white mustard, chinese kale, cauliflower, cabbage, sesame, broccoli, green mustard, lettuce, carrot, red spinach and celery. The experiment was arranged in a Randomized Block Design with 10 replications. Sample of 50 seeds were tested on different paper substrate including straw paper, filter paper, stencil paper, CD paper and sterilized filter paper, to identify the best alternative substrate. Result of  the study showed that stencil and CD papers as a substrate for seed viability testing performed 100% similarity compared to straw paper. When filter paper was used as standard substrate, there wasn't any paper has 100% similarity, but straw paper showed the highest (97.22%) followed by stencil paper (88.87%). Based on less than 5% coefficient of variation criteria, stencil paper was the best with 61.11% uniformity of seed viability data followed by straw paper (58.33%). In higher tolerance level with less than 10% coefficient of variance criteria, stencil paper was still the highest with 100% uniformity, followed by straw paper (97.22%). Stencil paper as germination substrate performed similar seed viability to the control straw and filter papers also produced high uniformity data. Stencil paper could be used for substrate viability testing of small seed with top of paper method.      Key words : Top of paper method, alternative, paper substrate, viability, coefficient of variance

Abstract

ABSTRACTPhysiological quality of soybean seeds was easily deteriorated during storage. The objectives of the research were to determine controlled deterioration test which could be used to evaluate soybean seed viability and to find the appropriate controlled deterioration test for estimating storability of soybean seed. The research was conducted at the quality control laboratory PT. BISI International, Tbk., Kediri since October 2012 until February 2013. The completely randomized design with four replications was used in the experiment by moisture content and deterioration periods as treatment. The results showed that the controlled deterioration periods to evaluate two varieties of soybean seed were same for 16 hours at 17.5% moisture content for Wilis and 15% moisture content for Detam-1. The result also showed that there were significant correlations between controlled deterioration values with actual values from 16 weeks storage periods, indicating controlled deterioration test periods could estimate storage periods. Verification of seed vigor relation to storability model showed there were no significant differences between germination and speed of germination between controlled deterioration and actual values. Simulation of soybean seed storability model with germination percentage after controlled deterioration as input variables could predict the storage periods.Keywords: Glycine max, rapid ageing, seed modelling, seed vigour, vigour index
