| 摘 要： | 对在日光温室条件下,测定的金太阳杏叶片净光合速率与其相关因子(大气CO2浓度、蒸腾速率、气温、叶温、光合有效辐射、相对湿度等)的数据,进行了灰色关联度分析,结果表明,在日光温室栽培条件下,影响金太阳杏叶片净光合速率的主导因子是光合有效辐射和蒸腾速率,其次是大气温度和相对湿度,大气CO2浓度影响相对较小.

| Abstract: | By using the relational grade analysis of grey system theory,the relational gray coefficient and grade on leaf net photosynthetic rate of sungold apricot grown in sunlight greenhouse and main ecological factors(CO2 concentration of atmosphere,photosynthesis active radiation,transpiration,the atmospheric temperature,leaf temperature,relative humidity)were analyzed.The result showed that the factors which seriously influenced leaf net photosynthetic rate of sungold apricot were photosynthesis active radiation and transpiration in sunlight greenhouse,the next were the atmospheric temperature and relative humidity,the last factor was atmospheric CO2 concentration of atmosphere. |
