为了了解产量的形成及抑制因素,对很多作物的源库关系的性质已进行了研究。尽管对甘薯的详细研究比较少,但普遍认为库的强度比源的潜力更为重要,并且在决定产量上,转移率可能比光合率更重要。近年来,我们做了若干试验,以检验这些关系对块根产量的影响。 In order to understand the formation and suppression of yield, the nature of source-sink relationships for many crops has been studied. Although detailed studies on sweet potato are relatively rare, it is generally accepted that the strength of the pool is more important than the potential of the source, and the rate of transfer may be more important than the rate of photosynthesis in determining yield. In recent years, we have done a number of experiments to test the impact of these relationships on tuber yield.
