不同水分胁迫对剑麻生理特性的影响
Effects of Different Water Stress on Physiological Characteristics of Agave sisalana
摘要
Abstract
[Objective]To study the effects of different water stress on the physiological characteristics of Agave sisalana.[Method]Pot experiment was used to study the effects of mild water stress (T1) and severe water stress (T2) on the growth and drought resistance of A.sisalana seedlings.[Result]The plant height,fresh weight,leaf water content and root vigor changed regularly by the order as CK>T1>T2 during the whole growing period.The relative electric conductivity(REC),POD activity ,free proline (Pro) content and malondialdehyde (MDA) content changed by the order as CK<T1<T2.The contents of N,P,K showed declining trends with the increasing of water stress.Along with prolonging of water stress time,the leaf water content showed an increasing trend under different treatments.REC and POD activity increased at first and then decreased in control (CK) and T1 treatments,and increased in T2 treatment.The content of MDA increased in T1 and T2 treatments.The content of N increased at first and then decreased in different treatments.The content of P decreased in different treatments.The content of K gradually increased in CK and T1 treatments,K content in T2 treatment gradually decreased.[Conclusion]The research results can provide theoretical basis for the drought-resistant cultivation of A.sisalana.关键词
