METODOLOGIA PADRONIZADA PARA O TESTE DE GERMINAÇÃO EM SEMENTES DE GRÃO-DE-BICO (Cicer arietinum L.)

Abstract

The objective of the present study was to determine the methodology for carrying out the germination test on chickpea seeds. Three tests were carried out: evaluation of different types of substrate / positioning; evaluation of the seed exposure temperature during germination; and evaluation of the data from the first count. The experiments were organized in a randomized design, factorial scheme 6 x 3 (cultivar x positioning / substrate), for tests I and 6 x 4 (cultivar x temperature) for test II, these two were performed in the analysis of variance and as compared media by the LSD media test. Germination evolution chart was prepared for trial III. The parameters analyzed were: germination, germination speed index and average germination time, for tests I and II and only germination in test III. Higher germination percentages and increased germination speed were observed when used or substrate paper roll. The extreme temperatures (15 and 30 ° C) are not favorable to the seedling formation process of this species. The germination test must be carried out on the substrate paper roll, at 20 ° C and with the data from the evaluation of the first count up to 6 days after sowing.
