中文摘要为研究延安燕沟流域5种传统作物的光合作用特性及其与环境因子的相关关系,运用美国产Li—6400便携式光合作用系统对5种作物的光合特性和环境因子进行了测定,结果表明:(1)西葫芦(Cuourbita papo)和甘蓝(Brassica olerarea)的净光合速率日变化呈"单峰型",即没有光合"午休"现象,而茄子(Solanum melongena L.)、黄瓜(Cucumis satovus L.)和甜瓜(Cucumis melo L.)均呈现明显"双峰型"特征,光合"午休"现象明显;(2)5种作物中甜瓜叶片的蒸腾速率最大,其他依次为西葫芦、甘蓝、黄瓜、茄子;(3)相对于甘蓝而言,茄子和黄瓜的气孔导度日变化相对平缓;(4)甘蓝的胞间CO2浓度呈"双峰型",茄子、黄瓜和甜瓜均呈现先下降后上升的趋势,即"V"型,西葫芦呈上升—下降—上升趋势,即"N"型;(5)5种作物的光合有效辐射(PAR)和相对湿度(RH)与净光合速率(Pn)均呈极显著正相关(p<0.01)
英文摘要Abstract:The photosynthetic characteristics of five traditional crops in Yangou Basin,Yan′an city and its correlation
 between the environmental factors were studied.The photosynthetic characteristics and environmental
 factors of five kinds of crops were investigated using Li—6400portable photosynthesis system.The results
 showed:(1)the diurnal changes of Pn of Cucurbita pepo L.and Brassica oleracea were a single-peak
curve which meant they didn′t have the phenomenon of‘midday depression of photosynthesis’,and the diurnal
 changes of Pn of Solanum melongena L.,Cucumis melo and Cucumis sativus Linn showed a typical double-
peak curve with a visible‘midday depression of photosynthesis’;(2)the diurnal changes of Tr was in
the order of Cucumis melo>Cucurbita pepo L.>Brassica oleracea>Cucumis sativus Linn>Solanum melongena
 L;(3)the diurnal changes of Gs of Solanum melongena L.and Cucumis sativus Linn were flater than
Brassica oleracea;(4)the diurnal changes of Ci of Brassica oleracea showed a double—peak curve,a‘Vtype’curve
 was showed in Solanum melongena L.,Cucumis sativus Linn and Cucumis melo,a‘N-type’
curve was showed in Cucurbita pepo L.;(5)there was a significant(P<0.01)positive relationship between
the Pn,PAR and RH in the five crops.
