Abstract:
Abstract: Zizyphus. jujube Mill.( Z.j M.)is one of the main ecological and economical tree species in semi-arid area of the west of Liaoning Province.In this region,the study of physiological feature will be significant to economic forest industrial development.Taking different cultivars Z.j M.as materials,which gas exchange and fluorescence physiological indexes characteristics were detected and analyzed by using Li-6400 portably photosynthetic measurement system in Chaoyang areas.The results showed that,the gas exchange and fluorescence physiological characteristics of different Z.j M.cultivars were significant difference.The value of stomatal conductance(Gs)，intercellular CO2 concentration（Ci）,limiting value of stomata and efficiency for solar energy utilization of Z.j M.‘Da Pingding Zao’ and Z.j M.‘Da Lingdang Zao’，and Z.j M.‘Jinsi Wangzao’ would be better than that of Z.j M.‘Jinsi Mizao’ and Z.j M.‘Sanxing Zao’；the value of Fv/Fo and Fv/Fm of Z.j M.‘Da Pingding Zao’ and Z.j M.‘Da Lingdang Zao’ were greater than that of Z.j M.‘Sanxing Zao’, Z.j M.‘Jinsi Mizao’,and Z.j M.‘Jinsi Wangzao’.According to the qP and NPQ value of the different Cultivars Z.j M.,it showed that the capability of the basic-level production of them was different,the order was： Z.j M.‘Sanxing Zao’< Z.j M.‘Jinsi Mizao’< Z.j M.‘Jinsi Wangzao’< Z.j M.‘Da Lingdang Zao’< Z.j M.‘Da Pingding Zao’；furthermore,the ability of adapted to intense sunlight of them was also different,the order was： Z.j M.‘Da Pingding Zao’> Z.j M.‘Jinsi Mizao’> Z.j M.‘Da Lingdang Zao’> Z.j M.‘Sanxing Zao’> Z.j M.‘Jinsi Wangzao’.In sum,it assumed that the photochemical characteristics of Z.j M.‘Da Pingding Zao’ and Z.j M.‘Da Lingdang Zao’,and Z.j M.‘Jinsi Wangzao’ would be better than that of Z.j M.‘Jinsi Mizao’ and Z.j M.‘Sanxing Zao’.
