摘    要:2008年初广西各蔗区甘蔗均遭受严重的寒害冻害,研究霜冻天气对主栽甘蔗品种生长及蔗糖分的影响对确保甘蔗持续生产,选育抗寒甘蔗品种具有重要意义。2009年1月霜冻天气对桂中地区主栽甘蔗品种生长及蔗糖分影响的研究结果表明,这次霜冻天气后甘蔗的受冻害症状明显,蔗糖分下降了0.21%-0.48%(绝对值),宿根蔗蔗糖分的降幅较新植蔗大;简纯度下降了0.37%~1.48%(绝对值),新植蔗的降幅较宿根蔗大。

关 键 词:霜冻天气  甘蔗  新台糖22号  生长  蔗糖分  桂中地区

Abstract:Almost all the sugarcane crop planted in Guangxi sugarcane areas was suffered from severe cold and freezing injury in the beginning of 2008. The present study has been conducted to study the influences of frosty weather on sucrose content and growth to ensure sustainable production of sugarcane and breeding of sugarcane varieties for cold tolerance. The results in the field experiment in 2009 showed severe morphological and physio-biochemical symptoms of cold injury. Sucrose content decreased by 0.21%-0.48% (absolute value, the same below), sucrose content of ratoon sugarcane dropped greatly compared with that of plant sugarcane, while apparent purity decreased by 0.37%-1.48%, the decrease amplitude of decrease in plant sugarcane was higher than that of ratoon sugarcane.
Keywords:frosty weather  sugarcane  ROC22  sucrose content  central areas of Guangxi
