类番茄茄(Solanum lycopersicoides)生长发育习性的研究

为了克服类番茄茄空间引种的困难 ,对类番茄茄的种子萌发、植株生长和开花结果习性进行了初步的研究。结果表明 ,类番茄茄接受短日反应的时间为 12 .75 h,S.lyccpersicoide种子在正常情况下不能萌发 ,用市售 5 0 % HCIO处理后 ,可顺利发芽。植株开花有昼开夜闭习性 ,自花授粉不结实 ,株间交结实率冬季为 4 %～ 5 % ,春季为 15 %～ 17% ,温室中栽培果实为绿色。

Study on the habits of Solanum lycopersicoidesgrowth and development

To overcome the difficulties of spatial introduction in Solanum lycopersicoides,the habits such as seed germination,plant growth, flowering and furit-setting of Solanum lycopersicoides were basically studied in this experiment.The results indicoted that the seed of Sdanum lycopersicoides doesn't germinate at the normal condition and the bowier can be oerconed by the treatment of seeds with 50% HClO.The flower opens at daytime and doses at night;Solanum lycopersicoides is self-sterile,fruit-setting rate by pollinated among plants is 4%～5% in the winter and 15%～17% in the spring.The fruits colaer is green in green house.The short light reaction time of Solanum lycopersicoides was 12.75 hours in this experiment.$$$$
