研究结果表明:高温和GA3处理均能有效解除彩色马蹄莲种球休眠,促进其发芽,而其中高温的作用更加明显."高温(22℃～25℃)+GA3(300 mg/kg,15 min)"处理对促进彩色马蹄莲种球发芽,解除休眠的效果最好,在60 d和80 d后发芽率分别达到53.3%和93.3%;并初步明确了球淀粉含量的降幅和种球的发芽率成正相关.一年生种球的最佳促进开花处理为"高温(22℃～25℃)+GA3(200 mg/kg,10 min)",处理后开花率约为36.7%.二年生种球、三年生种球的最佳处理为"高温(22℃～25℃)+GA3(300 mg/kg,10min)",处理后开花率分别为66.7%和83.3%.
研究結果錶明:高溫和GA3處理均能有效解除綵色馬蹄蓮種毬休眠,促進其髮芽,而其中高溫的作用更加明顯."高溫(22℃～25℃)+GA3(300 mg/kg,15 min)"處理對促進綵色馬蹄蓮種毬髮芽,解除休眠的效果最好,在60 d和80 d後髮芽率分彆達到53.3%和93.3%;併初步明確瞭毬澱粉含量的降幅和種毬的髮芽率成正相關.一年生種毬的最佳促進開花處理為"高溫(22℃～25℃)+GA3(200 mg/kg,10 min)",處理後開花率約為36.7%.二年生種毬、三年生種毬的最佳處理為"高溫(22℃～25℃)+GA3(300 mg/kg,10min)",處理後開花率分彆為66.7%和83.3%.
연구결과표명:고온화GA3처리균능유효해제채색마제련충구휴면,촉진기발아,이기중고온적작용경가명현."고온(22℃～25℃)+GA3(300 mg/kg,15 min)"처리대촉진채색마제련충구발아,해제휴면적효과최호,재60 d화80 d후발아솔분별체도53.3%화93.3%;병초보명학료구정분함량적강폭화충구적발아솔성정상관.일년생충구적최가촉진개화처리위"고온(22℃～25℃)+GA3(200 mg/kg,10 min)",처리후개화솔약위36.7%.이년생충구、삼년생충구적최가처리위"고온(22℃～25℃)+GA3(300 mg/kg,10min)",처리후개화솔분별위66.7%화83.3%.
The results showed:High temperature or GA3 was good at dormancy release and burgeon promoted for Zantedeschia hybrida tuber, high "temperature(22℃～25℃)+ GA3(300 mg/kg, 15 min)" was the most useful treatment to tuber's dormancy release, after 60 d,the burgeon rate was 53.3%,after 80 d,the burgeon rate was 93.3%. The experimentation showed in addition: the tubers which starch content reducing more burgeon earlier. High temperature (22～25℃)+ GA3 (200 mg/kg, 10 min)"was the most useful treatment to one year tuber's florescence promoted,the florescence rate was 36.7%."high temperature(22～25℃)+ GA3(300 mg/kg, 10 min)"was the most useful treatment to two and three years tuber's florescence promoted,the florescence rate was 66.7% and 83.3%.
