- 摘要:
- 运用灰色系统理论，分析了干旱处理与正常管理下“沙金红”、“玛瑙”和“山杏”净光合速率（Pn）与气孔导度（Gs）、胞间CO2浓度（Ci）、蒸腾速率（Tr）、叶片温度（Tleaf）、大气CO2浓度（Ca）、水分含量（H2O）、空气相对湿度（RH）、光合有效辐射（PAR）等主要生理生态参数的灰色关联系数及关联度，明确了干旱处理与正常管理下影响杏净光合速率各生态因子的主次关系。结果表明：正常管理下影响杏净光合速率最大的分别是蒸腾速率、光合有效辐射和叶片温度，干旱处理下影响杏净光合速率最大的分别是CO2浓度、气孔导度和叶片温度，而且不同品种影响其净光合速率的生态因子主次关系不同，同一品种在不同栽培环境条件下影响其净光合速率的生态因子主次关系也不同，生产上应针对不同品种、不同发育阶段制定相应的配套栽培措施。
- Abstract:
- By using the relational grade analysis of gray system theory，the relational gray coefficient and grade on leaf net photosynthetic rate (Pn) of three apricot cultivars (‘Shajinhong’,‘Mono’‘Shanxing’,which were cultivated under normal and drought conditions) and main ecological factors(Gs，Ci，Tr，Tleaf，Ca，H2O concentration of atmosphere，RH，PAR) were analyzed.The results showed that under normal condition,the factor which seriously influenced leaf Pn of apricot was Tr，PAR and Tleaf.Under drought condition,the factor which seriously influenced leaf Pn of apricot was Ca，Gs and Tleaf.There were different relational grade ranks in different cultivars，and for the same cultivar，there were different relational grade ranks under different condition，integrated cultural practices should be made on cultivar characteristics and developmental stage.
