説明
Water endurance at the seedling stage (14-26 days after seeding) was compared among 23 commercial cultivars of silage corn (Zea mays L.), in a pot experiment, by 2 watering treatments: waterlogging treatment with distilled water for 12 days, and non-stressed control treatment. At the end of 12-day treatments, the dry weight of whole plant parts was measured to calculate the water endurance index (WEI) by the dry weight ratio (Waterlogging treatment/Control treatment) for each cultivar. The WEI values of KD750, Kumiai-dent 122, SH9904, KD365, 34B39, Cecilia and ZX7605 were higher than those of the other 16 cultivars. In the waterlogging treatment, the cultivars with high WEI value decreased their dry weight of root slightly, but did not their dry weight of top. Generally, the lower the dry weight of whole parts was, the higher the WEI was, although ZX7605, Cecilia and 34B39 with high dry weight had relatively high WEI. The earliness was not related to their WEI values of the cultivars.
