- W2384920688 abstract "The study is to further confirm the comparatively adaptability of Amygdalus pedunculata Pall.through experiment,so as to provide theoretic basis for its enormous production of and sustainable development. The photosynthetic characteristics of A.pedunculata Pall.were studied with LI-6400 portable photosynthesis system in the Mu Us Desert area of Shenmu County in Yulin and nursery of Northwest A F University in Yangling of Shaanxi Province,including observation of its biological characteristics.Some photosynthetic parameters were separately measured in two regions,such as diurnal variation of net photosynthetic rate(Pn),and the response of leaf net photosynthesis to light level and to CO2 could be modelled by a non-rectangular hyperbola, a rectangular hyperbola,respectively,then the correlated parameters were obtained.The parameters were analyzed by single factor analysis of variance.The results show that in the aspect of biological characteristics,the yield of A.pedunculata Pall.in Shenmu is more than that in Yangling.Comparatively longer time is taken on the green leaves in Yangling.In the aspect of photosynthetic characteristics,the curves of diurnal variation of net photosynthesis rate in leaves of A.pedunculata Pall in the two test sites show two peaks,and midday depression of Pn(11∶00～14∶00) can be found in leaves of both areas.The LCP and LSP of A.pedunculata Pall.in Yangling and Shenmu is 49.08 μmol/(m2·s),1 512.5 μmol/(m2·s);21.44 μmol/(m2·s),1 500 μmol/(m2·s),respectively.CCP and CSP is 84.46 μmol/mol and 1 000 μmol/mol; 53.92 μmol/mol and 781.25 μmol/mol.A.pedunculata Pall.in differert regions shows significant difference on growth conditions and photosynthetic characteristics.The photosynthetic ability of A.pedunculata Pall in Shenmu is marked better than in Yangling,showing stronger adaptability and great efficiency in photosynthesis,especially to high light and light concentration of CO2." @default.
