毛茄种子形态特征及其萌发特性研究

Study on Morphological Characteristics and Germination Characteristic of Seeds of Solanum ferox Linn.

以栽培于广西药用植物园的毛茄为研究对象,进行种子萌发试验。结果表明:毛茄种子存在种皮障碍,播前预处理有助于加快萌发和齐苗;6 h,60℃恒温水浴或40 mg/L,1 h GA3处理是最佳的预处理方式;温度和光照是影响毛茄种子萌发的重要因素,种子在15/25℃变温条件下发芽率最高,光照能够促进种子的萌发。

This paper investigated on seeds germination of Solanum ferox Linn.The results showed that seeds coat of Solanun ferox had barriers,help to speed up seed germination and seedlings uniformity;the best pretreatment was 6 h,60℃ water bath or 40 mg/L,1 h GA3,temperature and light were important factor on seed germination of Solanum ferox,Fluctrating temperature of 15～25℃ was the highest germination rate,light can promoted seeds grmination of Solanum ferox.
