摘要适中的昼夜温度(20/15°vs.15/10°C)增加了大苏、孟加拉、苏伊洞、葵梅红、葵梅红、沙拉希尔和伟志七个荔枝品种的营养生长和开花。在较高温度(25/20℃和30/25℃)下，营养生长得到进一步促进，开花消失。温度对花序形成的类型也有影响。在20/15°C条件下，所有品种的顶芽均在15/10°C条件下形成圆锥花序，开花量的相对大小顺序为：‘Wai Chee’>；‘Salathiel’&Gt；‘Kwai May Pink’>；‘Tai So’>；‘Bengal’>；‘Souey East’>；‘Kwai May Red’。高温下生长旺盛的品种在20/15℃时穗数较少，15/10℃时无叶穗数较少，但叶片水势和地上部营养状况在不同温度下差异不大。温室栽培品种的生活力和开花率大体反映在花期和花期。
SummaryModerate day/night temperatures (20/15° v. 15/10°C) increased vegetative growth and reduced flowering in the seven litchi cvs Tai So, Bengal, Souey Tung, Kwai May Pink, Kwai May Red, Salathiel and Wai Chee. At higher temperatures (25/20° and 30/25°C), vegetative growth was promoted further and flowering eliminated. Temperature also influenced the type of inflorescence formed. More leaves were formed on the panicles of trees growing at 20/15° than at 15/10°C. All terminal shoots on all cultivars produced panicles at 15/10°C. The relative order for the amount of flowering at 20/15°C was: ‘Wai Chee’>‘Salathiel’>‘Kwai May Pink’>‘Tai So’>‘Bengal’>‘Souey Tung’>‘Kwai May Red’. Cultivars which were vigorous at high temperatures produced fewer panicles at 20/15°C and fewer leafless panicles at 15/10°C. Only small differences were observed in the leaf water potential and the nutrient status of the shoots at different temperatures. Vigour and flowering of the cultivars in the glasshouse generally reflected fi...
