摘要
对2种来源冬种马铃薯的形态指标、光合速率与块茎产量指标进行比较,并对其相关性进行研究.结果表明:冬种马铃薯的不同繁育株系在肇庆地区的地域适应性存在差异.冬种马铃薯的形态指标、光合速率及块茎产量均呈不同程度的正相关.采收前冬种马铃薯的株高、基径、根长、不定根数、叶片数、净光合速率、块茎数和块茎产量测定参数均可作为马铃薯产量的预测指标.
In this paper,the index of morphology,photosynthetic rates and tuber yields from two sources of winter potato had been compared,and correlations between these indexes had been studied.The results showed that region adaptabilities of different breeding strains from winter potato were varied in Zhaoqing.There appeared positive correlations between parameters of morphological index,photosynthetic rate and tuber yield from winter potato in different extent.The parameters of individual height,base diameter,root length,coronal root,leaf quantity,net photosynthetic rate,tuber quantity and tuber yield can be used for prediction about potato yield.
