| The relationship between wheat anti premature senescence ability and indexes (bud length, coleoptile length, radicle length, seminal root number, root activity, seed storage material transporting rate, total fresh weight, total dry weight, root and shoot dry weight, and dry matter content of germinated seeds) among 33 wheat (Triticum aestivum L.) varieties were studied through a germination experiment. The results showed that 7 indexes, including shoot length, coleoptile length, radicle length, seminal root number, root activity, total fresh weight, and root and shoot dry weight of germinated seed, all had no significant correlation with wheat anti premature senescence ability. Besides, both total dry weight and dry matter content of germinated seed had partial correlation with wheat anti premature senescence ability, while they could not be used as identification indexes of the anti premature senescence at wheat seed germination stage appropriately, due to the anti premature senescence wheat varieties and typical premature senescence ones could not be accurately distinguished by total dry weight and the dry matter content of germinated seed. However, there is significant correlation between the seed storage material transporting rate and wheat anti premature senescence ability,so the seed storage material transporting rate might be used as preliminary identification index of the anti premature senescence at wheat seed germination stage. |
