通过发芽试验研究了温度与光照、消毒方法、浸种温度、3种外源激素(GA3 、6-BA、NAA)处理对北美红杉(Sequoia sempervirens)种子萌发的影响.结果表明,北美红杉种子在25℃/15℃全光照条件下萌发效果较好;0.1% KMnO4溶液消毒12 h与1%NaClO溶液消毒0.5h可显著提高种子的萌发能力;北美红杉种子的浸种温度以45℃为宜;外源激素促进北美红杉种子萌发的效果并不明显,500 mg/L GA3促进种子发芽,6-BA和NAA抑制种子发芽,NAA的抑制能力较强.
Study on Germination Characteristics of Sequoia sempervirens Seeds
The effects of different temperature and light, disinfection, soaking temperature and 3 kinds of exogenous growth regulator ( GA3, 6-BA, NAA) on seed germination of Sequoia sempervirens were studied in this paper. The results showed that the germination effect was better than others with 25 ℃ to 15 ℃ under the conditions of full light. Disinfection of 0.1 % KMnO4 for 12 h and 1 % NaClO for0. 5 h could promote germination significantly. The result indicated that the best soaking temperature was 45 X.. Exogenous growth regulator to promote seed germination Sequoia sempervirens was not obvious. 500 mg/L GA3 could promote germination. 6-BA and NAA showed inhibitory effect on the germination, and the inhibitory effect of NAA was better than that of 6-BA.
