我之所以说这是一种可能性,是因为:
1,新西兰土中的boron含量比较低,
2,It (boron) is …… needed for the growth of the pollen tube during flower pollination and is therefore important for good seed set and fruit development. Boron is thought to increase nectar production by flowers, and this attracts pollinating insects.(对不起,我比较懒,这里是引述他人英文)。
要让这个可能性得到进一步的确认(对或错),可能要由比较专业的机构,做比较详细的分析,包括eggplant对boron的需求量。作者: viticulture 时间: 2013-2-2 22:16:20
