- 摘要:
- 为提高三角梅的观赏品质,以四年生盆栽艳红三角梅为试验材料,研究光质、生长调节剂和紫光+生长调节剂对其生理指标及开花的影响。结果表明:紫光、红光、白光及自然光作用下,紫光更有利于三角梅叶绿素的合成,促进花芽的形成,提升花卉观赏价值;多效唑、赤霉素、缩节胺及矮壮素4种调节剂药后45 d,750 mg?kg-1多效唑表现最好,开花数达到116.67朵;紫光+750 mg?kg-1多效唑,能有效促进植株叶绿素的合成,叶绿素含量达到51.23 mg?g-1,互作效果明显,三角梅开花数量达到146.00朵,显著高于CK。
- Abstract:
- In order to improve the ornamental quality of Bougainvillea,with four years of Bougainvillea Brilliant Red as experimental material, the influence of different light quality,growth regulator and purple light + growth regulator on the flowering and other physiological indicators of Bougainvillea was studied.The results showed that under purple,red,white and natural light,purple light was more favorable to the synthesis of chlorophyll, promoted the formation of buds and improved the ornamental value of flowers. After spraying PP333,GA,DPC and CCC 45 d,750 mg?kg-1 PP333 performs best,the number of flower reached 116.67;Purple light +750 mg?kg-1 PP333 could effectively promote the synthesis of chlorophyll in plants,the chlorophyll content reached 51.23 mg?g chlorophyll,had obvious interactions,the number of flower reached 146.00,and significantly higher than CK.
