核桃是我省重要的木本油料树种。我省核桃产量居全国之冠。尤其汾阳、孝义、左权三个县产量列居全国核桃五个高产县的前三名。据1980年统计,全省有3100多万株核桃,年产仅5700万斤,平均株产不足2斤。研究核桃花芽生物学,对提高核桃产量、品质,进一步挖掘生产潜力有非常重要的意义。 Walnut is an important woody oilseed species in our province. The province’s output of walnut ranks first in the country. In particular, Fenyang, Xiaoyi, Zuoquan output of three counties in the country’s top five high-yielding walnut counties. According to statistics in 1980, the province has more than 3100 walnut trees, with an annual output of only 57 million kilos, with an average yield of less than 2 pounds. Research walnut flower bud biology, to improve walnut yield, quality, further tap the potential of production is very important.
