1968年采收的261份黄麻资源种子,在实验室常温条件下,用干燥器密闭贮藏,其中长果种49份,圆果种212份。1989年测定结果表明,发芽率81%以上的品种份数,占贮藏总份数的63.2%,发芽率61—80%的占22.2%,发芽率60%以下的占14.6%。1991—1992两年种植贮藏的长、圆果种共12份,没有观察到生育特性、植株形态和单株生产力的明显变化。1993年4月测定11份长、圆果种品种的种子含水量范围为2.91—4.64%,有9份品种的发芽率达90%以上,表明黄麻种质资源贮藏在内放干燥剂的干燥器内是安全的。 The 261 jute resource seeds collected in 1968 were stored in sealed containers at room temperature in a laboratory, of which 49 were long fruits and 212 were round fruits. The results of determination in 1989 showed that the percentage of varieties with the germination rate above 81% accounted for 63.2% of the total number of stored seeds, the germination rate was 61-80%, and the percentage of germination rate below 60% accounted for 14.6% %. During the two years 1991-1992, a total of 12 species of long and round fruits were planted and stored. No significant changes in fertility characteristics, plant morphology and plant productivity were observed. In April 1993, the seed moisture content of 11 long and round fruit cultivars was determined to be 2.91-4.64%. The germination rate of 9 cultivars was more than 90%, indicating that jute germplasm resources were stored in dry Dryer inside the agent is safe.
