不同成熟期杏品种光合特性差异分析
Differential Analysis of Photosynthetic Characteristics of Different Maturity Apricot Varieties in Xinjiang
摘要
Abstract
[Objective] The aim of this paper is to study the photosynthetic characteristic differences of different maturity apricot varieties,and provide theoretical basis for the study on apricot fruit growth characteristics and late-maturing mechanism of the apricot ' Dongxing'.[Method] Measuring its PAR/CO2-Pn response curve of selected different maturity apricot varieties during the second slow period of fruit development (early June to early July).[Result] The trends of different maturity apricot varieties' PAR/CO2 -Pn response curve are basically the same,but simulation parameter values of photosynthetic characteristics showed significant difference.Early maturity variety:'Baduyulvke'、' Kumaiti' had the strongest photosynthetic capacity and the selected apricot varieties ' Daguohuanna',Yabulakejianali'relatively had the rather weak capacity.The most late-maturing apricot variety ' Dongxing' was between them.Principal elements which affect fruit development time of different maturity apricot varieties in photosynthesis were AQY,LSP,CE,CCP and CSP.In addition to these factors,the higher Rd is another key factor in delaving its mature.[Conclusion] The photosynthetic characteristic of different maturity Xinjiang apricot varieties showed tiny difference in the same group and significant difference between different groups.AQY,LSP,CE,CCP,CSP are bound up with the time of apricot fruit development between simulation parameter values of photosynthetic characteristics.Higher Rd value is one of the key factors which lead to lengthening time in the development of the most late-maturing apricot variety ' Dongxing'.关键词
