-
摘要: 将难开花的果蔗和甘蔗栽培品种置于12.25小时光照处理下,其中每天以蓝光和远红光分别于上午6:00—8:00和下午4:00—6:15在光周期室作补助光照,以代替露天的阳光;甘蔗栽培品种还用常规的渐减日长法作对照。本处理于1991年7月1日至12月20日进行,结果首次诱使福建省地方优良果蔗——同安果蔗(Saccharum officinarum L.)开花以及甘蔗栽培品种CP65-357、闽糖81-235、赣蔗65-542和粤糖65-906分别于12月上中旬开花,而采用渐减日长法处理的上述甘蔗栽培品种,除CP65-357外,均不能开花。Abstract: Non-flowering chewing cane and sugarcane varieties were subjected to 12.25-hour photoperiodic treatment supplemented with blue and far-red lights daily at 6 : 00 to 8 : 00 a.m.and 4 : 00 to 6 : 15 p.m.separately to replace outdoor illumination for the florescent induction and conventional treatment of gradually shortening day-length was also used as the control.The fine chewing cane in Fujian province, Tong-an chewing cane (Saccharum officinarum L.) was inducted to bloom in the first time and the cultural varieties, CP65-357, Mingtang 81-235, Ganzhe 65-542 and Yuetang 65-906 were also inducted to bloom but none of abovementioned sugarcane varieties flowered by control treatment of gradually shortening day-length except CP 65-357.
