摘要
研究不同处理方法及常温贮藏时间对蔓性千斤拔种子发芽的影响。结果表明:(1)浓硫酸和机械磨擦处理均能显著改善种子的发芽状况,其中浓硫酸处理以处理10~15min最佳,其发芽率、发芽势、发芽指数分别较对照高2倍、14.6倍和14.29倍;机械处理以处理180s最佳,其发芽率、发芽势和发芽指数分别较对照高2.67倍、15.17倍和7.51倍。(2)贮藏时间以当年种子的发芽特性最佳,常温下贮藏1年,种子发芽率下降至83%,与当年种子发芽率无明显差异;贮藏2年,发芽率降至65.5%,与当年种子发芽率达到显著差异;贮藏3年,与当年采收种发芽率差异达到极显著水平。
The way of seed storage and treatment ofMoghania philippinensis was studied. The results showed: (1)With the way of 98% H2SO4 treatment and machine rubbing,the germination percentage could increase obviously. It is the best way that the seed was dipped in 98% H2SO4 for 10 -15 min,germination percentage, germination energy and index increased 2,14.6 and 14.29 times respectively compared with ck. The treatment of machine in 180 s was the best way, germinating energy and germinant index increased 2. 67,15.17 and 7.51 times respectively compared with ck. (2)The germinant characteristic of new seed gained in the same year was the best. The germinant percentage decreased to 83% after the seeds were stored 1 year at ordinary temperature,which was not obvious compared with ck. But the germinant percentage decreased to 65.5% or lower after stored 2 years and 3 years which was obvious compared with ck.
