Pengaruh Jenis dan Jumlah Substrat Kertas Terhadap Viabilitas Benih Kacang Buncis, Pare, Kedelai, dan Kacang Panjang.

Abstract

Optimum amounts of different paper substrates were important for efficient viability testing of seeds. The objective of the experiment was to study the effects of variety and amount of paper substrate on seed viability of Phaseolus vulgaris, Momordica charantia, Glycine max and Vigna sinensis in order to determine the optimum amounts of different testing substrate papers. The experiment were conducted in The Seed Science and Technology Laboratory, Bogor Agriculture University from February 2008 to May 2009. Separated experiments were conducted for different crop seeds where a Randomized Block Design with ten replications and two treatment factors i.e. varieties of substrate paper (straw, stencil and CD) and amount of substrate paper (2, 3, 4, 5 sheets) were applied to each experiment. The result showed that 4 sheets of straw paper, 5 sheets of stencil paper and 5 sheets of CD paper were similar to the reference substrate (5 sheets of straw paper) for germination percentage variable of all crop seeds except Momordica charantia. There were different amounts and varieties of substrate papers producing similar vigor index to the reference substrate among crop seeds. For dry weight of normal seedling variable, 4 sheets of straw paper could substitute the reference for all of crop seeds. Almost all of the seeds tested with different amount and variety of substrates paper performed high similarity (no significant difference) to the reference for maximum growth potential variable. Key words: variety, amount, paper substrate, seed viability
