蓝光与远红光诱导甘蔗开花研究续报

将难开花的果蔗（热带种）和甘蔗栽培品种置于１２．２５小时光照处理下，每天以蓝光和远红光于上午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。１９９１年７月１日至１２月２０日进行此种处理，结果首次在地处亚热带的福建省漳州市（北纬２４°３０＇，东经１１７°３９＇）诱导福建地方优良果蔗──同安果蔗以及甘蔗栽培品种（ＣＰ６５－３５７、赣蔗６５－５４２、闽糖８１－２３５和粤糖６５－９０６等分别于１２月上中旬开花。１９９２年６月２３日至１９９３年１月９日，又用此种方法，并经适当改进，进行处理，结果又诱导福建省另一优良地方果蔗品种──马鞍果蔗开花，同安果蔗也再次被诱导开花，福建省大面积的栽培品种闽糖７０－６１１、闽糖７０３、闽糖７６－２和闽糖８１－３３５等首次被诱导开花。

Continuous Report on the Florescent Induction of Sugarcane by Blue and Far-red lights

Non-flowering chewing cane (Saccharum officinarum L.) and sugarcane varieties were subjected to 12. 25-hours 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 floescent induction from July 1 to December 20, 1991.
