低温对于禾谷类作物种子的影响,很早以前便有许多学者加以研究,唯对大麻种子的影响尚少有报导。本试验的目的在于查明不同含水量的大麻种子经短期天然另下低温作用后种用品质的影响,为黑龙江省外销的大麻种子在运输途中经受严寒作用后是否会变质的问题,提供部分数据。本项试验所用的材料为黑龙江省1956年产的、1957年外销的大麻(Cannabis sa-tiva)种子。其中一批种子的原有含水量为12.80%,发芽率为92.4%;另一批种子的 The effect of low temperature on the seeds of cereal crops has long been studied by many scholars, but the impact on the seeds of cannabis is seldom reported. The purpose of this experiment is to find out the effect of seed quality of cannabis seeds with different water content after short-term natural low-temperature effect, and to provide some data for the problem that the cannabis seeds exported from Heilongjiang Province will be deteriorated after being exposed to the cold during transport . The materials used in this experiment were Cannabis sa-tiva seeds which were exported in 1956 in Heilongjiang Province and exported in 1957. One of the original seed moisture content of 12.80%, the germination rate was 92.4%; another batch of seeds
