摘要
魁蜜、金丰的年周期与日周期光合强度变化,皆为双峰曲线型.一年中以春季光合强度为最高,5月底开始由高潮逐渐转向低潮;一天中以上午9点左右为最高,12～14点为最低.而雄株的年周期与日周期光合强度变化皆为单峰曲线,并且光合高峰出现在一年中的夏季和一天中的中午高温时.形成双峰曲线的原因显然与温度有关,而单峰曲线的形成则可能与雄株的固有特性有关.金丰的光合强度比魁蜜的强,这与金丰的晚熟、丰产性相吻合;而雄株的光合强度在一年中始终保持较高的平稳状态.
Both annual variation and diurnal variation of the photosynthetic intensity of the femaleplants of Jinfeng(79-3)and kuimi(79-1)varieties of chinese kiwifruit(Actinidia chinensisplanch)appeared to be a double-peaked curve pattern.During the period of the year,thephotosynthetic intensity reached its peak in spring and started to decline at the end of May;and in the period of the day,the peak occurred at 9 a.m.and the lowest point at the time be-tween 12～14 p.m.While of the male,both the annual variation and the diurnal variation ofthe photosynthetic intensity appeared to be a single-peaked curve pattern.The peak occurredin summer of the year and at noon of the day when the temperature was high.The reason forthe double-peaked curve pattern is related to the temperature,while for the single-peakedcurve pattern may be related to the special properties of the male itself.The photosynthetic capacity of Jinfeng kept a higher level than that of kuimi,which isidentical with its late maturity and high production.The male,however,kept a constant high level all the year.
