尽管净光合率(Pn)与作物经济产量之间缺乏稳定而显著的相关,但产量在很大程度上仍然是由Pn潜力和分配到收获部份的光合产物来决定的。生殖生长期乃至衰老期的Pn及其与籽实产量相关上的差异,很可能大于营养生长期的。有关甘薯净光合率潜力的文献不多。Hahn曾报导,甘薯的Pn为12.0毫克CO_2/
Although there is a significant and significant correlation between net photosynthetic rate (Pn) and lack of stability between crop economic yields, yields are still largely determined by Pn potential and photosynthate distribution to harvested parts. Pn in reproductive and even senescent periods and their correlation with seed yield are likely to be greater than vegetative growth. There is not much literature on the potential of net photosynthetic rate in sweet potato. Hahn has reported that sweet potato Pn is 12.0 mg CO 2 /
