不同生育时期干旱胁迫对花生生长发育和复水后补偿效应的影响
Effects of drought stress on peanut growth during different growth stages and compensatory effect after water recovery
摘要
Abstract
Through artificial water - controlled methods, the effects of drought stress at different growth stages on growth and development and compensatory effect after water recovery of peanut (Arachis hypogaea L. ) were studied under pool culture in water proof installations. The results indicated that the plant height, LAI (leaf area index) , the dry weight of shoot and pod of peanut all decreased at various levels. With the prolongation of drought stress treatment, their decrease range amplified under drought stress at different growth stage. The drought stress at pod filling and seedling stage had relatively less effect on plant growth of peanut. The compensatory effect after water recovery was relatively greater at seedling stage. The drought stress at flower - pegging and pod - setting stage had relatively greater effects on the plant growth of peanut, and the compensatory effect after water recovery was negligible at these stages. The drought stress had the least effect on pod yield of peanut and it had increasingly greater effect at pod filling and mature stage, flower - pegging and pod setting stage. The effects of drought stress at seedling stage on pod yield of peanut was mainly relevant to the decrease of valid pod number. The effects of drought stress at pod - filling and mature stage on pod yield of peanut was mainly relevant to the decrease of pod plumpness. The effects of drought stress at flower - pegging and pod setting stage on pod yield of peanut were the combined effects of low valid pod number and low pod plumpness.关键词
