种球规格及GA_3处理对彩色马蹄莲产花性之影响(简报)

EFFECTS OF TUBER SIZE AND GA_3 TREATMENT ON CUTFLOWER PRODUCTION OF Zantedschina antedschia

研究了彩色马蹄莲细菌性软腐病菌落的生长与温度的关系 ;不同种球规格及GA3处理对彩色马蹄莲花期、产花量和质量的影响。结果表明 ,2 7℃以上高温会明显加重细菌性软腐病的发生 ;大规格种球的始花期早于中、小规格种球 ,产量和质量也均高于中、小规格种球 ;

The relationship between colony culture of Erwin ia catovora var. caro tovora causing soft rot of Zantedschina antedschi a and incubation temperature and the effects of tuber size and GA 3 treatment on cutflower output and quality of Z.antedschia were studied. The results s howed that the temperature above 27℃ would significantly increase the soft rot occuring.The bigger the tuber size was,the higher and better the yield and quali ty of cutflower production were.The results also showed that GA 3 treatment cou ld significantly raise output of flowers.
