| 摘 要： | 在自然条件下,利用Li-6400对青皮软籽石榴和红皮石榴的净光合速率、气孔导度以及胞间CO2浓度等光合生理特性进行测定和对比分析。结果表明:2个品种的净光合速率和气孔导度日变化均为双峰曲线,2个品种均有明显的"午休"现象,但青皮软籽的净光合速率和气孔导度略高于红皮;2个品种的胞间CO2浓度与净光合速率均呈负相关,且都在"午休"期间达到最小值,但红皮的胞间CO2浓度略高于青皮软籽石榴。

| Abstract: | Photosynthetic rate currency,intercellular and carbon dioxide concentration of the green-peel soft-seeded pomegranate and red-peel pomegranate under natural conditions were studied and compared by using the Li-6400 portable photosynthesis system.The results showed that the curve of diurnal variation of leaf photosynthesis and pore currency of the two varieties showed two peaks,both with the obvious lunch break feature.But the photosynthetic rate and pore currency of green-peel soft-seeded pomegranate was hi... |
