Abstract

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
