摘要
以克撒西巴斯马(XanthiBasma)、柯马蒂尼巴斯马(KomotiniBasma)为供试品种,研究了香料烟在云南保山香料烟产区的光合特性,研究表明,香料烟的光合速率日变化呈现典型的双峰型,这可能与气孔限制有关,其光合饱和点较高,在1600μmol·m-2·s-1左右。不同品种间的光合速率差异较大,在供试的7个品种中,杰尼克的光合速率最高,卡拉巴格拉的最低。
The photosynthesis characters of oriental tobacco were investigated in Baoshan,Yunnan Province.The results showed that diurnal variations of photosynthesis rate were a classic double-peaks type and there was midday depression caused partly by lowering of stomatal conductance.The oriental tobacco had a higher light saturation point of photosynthesis,and there were great differences in photosynthesis rate among different varieties,Ganik had the highest photosynthesis rate among those varieties.
