chinois. 研究了黄淮海改良型节能日光温室内与露地条件下凯特杏叶片结构和光合特性.结果表明,日光温室内凯特杏叶片干鲜重比、比叶重均小于露地,叶绿素含量增加,新梢显著加长,单叶面积显著扩大,叶片总厚度和栅栏组织厚度显著低于露地,气孔密度下降,气孔长度、宽度均小于露地,气孔长度不存在显著差异.叶片的净光合速率的日变化呈双峰曲线,净光合速率日最大值和日平均值都表现为露地高于温室,温室南部高于中部和北部.[著者文摘]

The experiment was conducted on the photosynthesis and the structure in leaves of Katy Apricot grown in improved greenhouse of Huanghuaihai and in the open field.The results showed that cultivation conditions,the dry and fresh leaf weight ratio and specific leaf weight（SLW） were less than those in the open field;the chlorophyll content was increased,the new shoots were obviously lengthened,the single leaf area were obviously expand,the thickness of the total leaves and the palisade tissue were obviously lower than those in the open field,the stomata density,stomata length and stomata width were all lower than those in the open field,and the stomata length had no significant difference.The net photosynthetic rate showed a diurnal variation of double-peak curve,the daily maximum and the daily average of the net photosynthetic rate in the open field was higher than those in the greenhouse,those of the southern parts were higher than those in the central and the northern parts.[著者文摘]
