大量研究表明，不同菜豆品种对低磷土壤的忍耐能力存在基因型差异［１～７］。有研究发现菜豆有两个独立的基因库（ＭＡ和ＡＮ），其中ＡＮ基因库的大粒种菜豆颇具有高磷效率潜力，但对于其耐低磷的形态和生理生化基础的研究还不多。Ｙａｎ通过一系列试验，初步提出了与大... Numerous studies have shown that there are genotype differences in the tolerance of different kidney bean varieties to low-phosphorus soils [1-7]. Studies have found that there are two independent gene banks (MA and AN) in the kidney bean. Among them, the large-seed kidney bean in the AN gene bank has the potential of high-phosphorus efficiency, but there are not many studies on the physiological and biochemical basis for its low-phosphorus tolerance. Yan through a series of experiments, initially proposed with the ...
