摘    要:为了明确小花溲疏种子发芽的适宜条件,研究了不同种源、温度、药剂及栽培基质对溲疏种子萌发的影响。结果表明:不同种源的溲疏种子发芽率、开始萌发的时间和出现萌发高峰的时间均有差异;野生溲疏种子最适发芽温度为20~25℃;GA3、KNO3、KH2PO4等化学药剂对野生溲疏种子的萌发均有抑制作用;河沙、蛭石等播种基质有利于种子的萌发,而粘重的园土不利于其萌发。

关 键 词:溲疏  种子  温度  基质  GA3

Abstract:The germination of the Deutzia parviflora Bge seeds were studied with different places,temperatures,drugs and culture media.The results showed that the germination rate were of diversity among places and varieties.The time of sprouting and sprout peak of seeds were different.The optimum temperature was 20~25℃ for the seed of wild Deutzia parviflora Bge.GA_3、KNO_3、KH_2PO_4 restrained seeds sprouting;Sand and vermiculite were beneficial to the seeds sprouting,but clay was not suitable.
Keywords:Deutzia parviflora Bge  seed  temperature  medium  wild  GA3
