摘要
为探索美国黑莓优质、丰产栽培技术,对黑莓的光合特性进行了研究。结果表明,在河北省文安县栽培的黑莓叶片光合速率日变化呈双峰曲线,最高峰在9时,次高峰在13时,存在“午休”现象。光合速率的季节变化亦呈双峰曲线,最高峰在6月份,次高峰在8月份。光合速率的光补偿点和饱和点分别为60μmol.m-2.s-1和1 380μmol.m-2.s-1。
In order to develope a set of cultivation techniques for high quality and high yield, the photosynthetic characteristics of American blackberry were studied. The results showed that, in Wen＇an county of Hebei Province, its daily variations were found as a double-peak curve whose highest peak occurred at 9：00, and the sub-peak at 13：00. So its daily variations of photosynthetic rate were featured with ＂Noon rest＂. As for its yearly variations, another double-peak curve was observed for its photosynthesis, the highest in Jun and the sub-peak in August. Research also indicated that light saturation point and light compensation point of the berry were 60 μmol·m^-2·s^-1 and 1 380 μmol·m^-2·s^-1 respectively.
