盐胁迫下四种蓝靛果忍冬的光合特征研究
|
摘要
以4种蓝靛果忍冬为试材,采用等渗条件控制试验,设置0.2%、0.4%、0.6%盐胁迫,研究其在盐胁迫处理下的光合速率(P_n)、蒸腾速率(T_r)、气孔导度(G_s)和胞间CO_2浓度(C_i)的光合响应特性,运用显著性分析、量化评估、隶属函数及主成分分析法对其耐盐性进行综合评定,为蓝靛果忍冬抗盐生理机制的研究提供参考。结果表明:随盐胁迫的加剧,4个蓝靛果忍冬品种在不同盐胁迫处理后的光合速率、蒸腾速率、气孔导度和胞间CO_2浓度变化规律各不相同,其主导因素也不同,经过分析可得"瓦修甘斯卡亚"和"北日勒"受盐胁迫后光合速率(P_n)下降分为2个时期,2%时以气孔因素为主,4%以后则以非气孔因素为主。而"伊利亚达""巴克恰尔斯卡亚"的光合速率(P_n)下降因素主要为非气孔因素。综合分析认为,盐胁迫下蓝靛果忍冬光合作用降低是多因素共同作用的结果,结合该研究多种分析评定,可以得出,"巴克恰尔斯卡亚"的耐盐能力相对较强,而"伊利亚达"的耐盐能力最弱。
The photosynthetic response of four Lonicera edulis varieties to photosynthetic rate(P_n),transpiration rate(T_r),stomatal conductance(G_s)and intercellular CO_2 concentration(C_i)under NaCl stress was studied using an isotonic condition control experiment,0.2%,0.4%,0.6% of different NaCl stress were set,comprehensive evaluation were used by significant analysis,quantitative evaluation,membership fuction and principle component analysis.The results showed that the photosynthetic rate,transpiration rate,stomatal conductance,and intercellular CO_2 concentration of four Lonicera edulis varieties had significant differences with increasing NaCl stress.Among them,net photosynthetic rate(P_n),transpiration rate(T_r),stomatal conductance(G_s)decreased in turn,and intercellular CO_2 concentration(C_i)slowly increased.According to comprehensive analysis,NaCl stress directly affects the photosynthetic physiology of Lonicera edulis.Combined with various analysis and evaluation in this study,‘Bakqarskaya'had relatively high salt tolerance,and ‘Yilyada'had the lowest salt tolerance.
