低磷胁迫对8个青稞品种苗期关键农艺性状的影响
Low Phosphorus Stress Affects Key Agronomic Traits in Seedlings of 8 Hulless Barley Varieties
摘要
Abstract
To reveal the agronomic traits of hulless barley seedlings under low phosphorus stress,we measured the agronomic traits of seedlings in hydroponic culture and under low phosphorus for 8 hulless barely varieties.Furthermore,each hulless barely variety was evaluated for its tolerance to low phosphorus.The results showed that under low phosphorus stress,all hulless barley varieties showcased significant decreases in plant height,root length,plant fresh weight,plant dry weight,root fresh weight,and root dry weight compared with those of the same hulless barley varieties under normal culture conditions,while the root-to-shoot ratio demonstrated no significant difference between normal culture conditions and low phosphorus stress.A comprehensive analysis of agronomic traits under different cultivation conditions revealed that root dry weight,plant height,and plant fresh weight could be used as crucial indicators to evaluate the low phosphorus tolerance.Among them,root dry weight was the most important agronomic trait for screening hulless barley varieties with low phosphorus tolerance.The subordinate function analysis showed that the low phosphorus tolerance of the eight varieties of hulless barley followed the trend of'Purple Kangqing'>'Huangqing 1'>'Dulihuang'>'Kunlun 14'>'Himalaya 22'>'Luolongzong'>'Tewu'>'Mozhu hulless barely'.关键词
