氮胁迫下不同黑木相思基因型综合评价
Comprehensive Evaluation in Different Genotypes of Acacia melanoxylon under Nitrogen Deficiency Stress
[目的]探究不同黑木相思基因型对缺氮胁迫的生长、生理生化响应,为黑木相思优良抗逆早期选育提供理论依据[方法]本研究以 4个黑木相思基因型(F1、SR3、SR14和SR17)幼苗为对象,以改良霍格兰营养液为基础,利用沙培盆栽试验方法,设置CK(16mmol·L-1 N素)和-N(0 mmol·L-1 N素)两个氮水平,探究氮缺乏对4个黑木相思基因型幼苗的生长和生理生化特性的影响,并用主成分分析结合隶属函数进行耐低氮能力综合评价。[结果]缺氮下,4个…查看全部>>
[Objective]To explore the growth,physiological and biochemical responses of different Acacia melanoxylon genotypes to nitrogen deficiency stress,and to provide a theoretical basis for early breeding of Acacia melanoxylon with excellent stress resistance.[Method]In this study,4 genotypes(F1,SR3,SR14 and SR17)seedlings of Acacia melanoxylon as objects,based on the improved Hoagland nutrient solution,using the sand culture pot test method,set CK(16mmol·L-1 N)an…查看全部>>
