分蘖期旱涝交替胁迫对水稻叶片性状的影响
Effects of Alternative Stress of Drought and Waterlogging on Leaf Character
摘要
Abstract
Pot experiments were performed to research the effects of alternative continuous stress of drought-waterlogging-drought at tillering stage (water depth of waterlogging at tillering stage was 10 cm) on rice leaf water content,leaf area,leaf angle,leaf shape at different leaf position and panicle lengths,and two treatments were set up (light drought (T-LD) and severe drought (T-HD)) using regular irrigation (CK) as the control.The results showed that rice leaf water content decreased under drought stress at tillering stage,and the more sever the stress,the lower the leaf water content;The leaf water content of T-HD treatment was at a high level in the late growth stage of rice,which was 69.3 7％.Alternative stress of drought and waterlogging at tillering stage had a significant influence on leaf area,and leaf area was still at a low level after rewatering (leaf area of T-LD,T-HD treatments were only 42.43％,53.90％ of CK,respectively),and LMA of T-HD treatment in the ripening period was 1.01％ less than that of CK.Upper leaf angle of rice showed greater trend than CK under alternative stress of drought and waterlogging;in heading-flowering stage,the rice flag leaf and second leaf grew rapidly under water stress treatments of tillering stage.关键词
