Abstract:

In hydroponics and 20% PEG for drought, the drought resistance of 5 different wheat varieties was examined with germination percentage, coleoptile length, numbers of radicles and main radicle length. The results showed that significant differences in drought resistance were observed among 5 different cultivars. The drought resistance of ‘Mai 1’ was the strongest, ‘Mai 99’, ‘Shi 4185’, ‘Beinongda 3383’ were the second, and ‘Shiluan 02-1’ were the weakest. Length of embryo sprout sheath and relative germination percentage of seeds are the reliable indexes, length of the main embryo root and embryo root quantity are the reference indexes.
