摘要:

      支撑物倾角的变化对攀援植物光合特性具有重要影响。本研究以山东道地药材栝楼(Trichosanthes kirilowii)为研究对象,比较了支撑物倾角为60°(搭架式栽培模式)和90°(棚架式栽培模式)下栝楼光合特性和蒸腾生理的差异。结果发现,两支撑物倾角下栝楼净光合速率日变化表现出相似的变化趋势,从各监测点来看,90°支撑物倾角下栝楼净光合速率均高于60°支撑物倾角。两支撑物倾角下栝楼光饱和点和光补偿点无显著性差异,CO2饱和点和补偿点也无显著性差异。该研究表明棚架式栽培模式下栝楼透光率、光能利用率和有机物积累效率均高于搭架式栽培模式。

Abstract:

        Staddle obliquity significantly influenced the photosynthetic characters of climbing plants. We compared the differences of photosynthetic characters and transpiration physiology of Trichosanthes kirilowii for two staddle obliquities (60° and 90°). Results show that its diurnal change of net photosynthetic rate under two cultivating modes demonstrates similar tendency. Its net photosynthetic rate of 90° is higher than that of 60°. Significant difference does not exist for light saturation point, light compensation point, CO2 saturation point and CO2 compensation point. The research shows that light transmittance of 90° is higher than that of 60°. Light energy utilization rate and organic accumulation efficiency of 90° are higher than those of 60°.

Key words: staddle obliquity, Trichosanthes kirilowii, photosynthetic character, transpiration physiology
