蔗糖分影响论文参考文献：
摘 要 粤糖60号是广州甘蔗糖业研究选育的优良甘蔗新品种,具有早熟、高产、高糖、农艺性状优良等特性.本试验在湛江蔗区研究3个植期对粤糖60号产量和蔗糖分的影响.结果表明：粤糖60号在湛江徐闻、遂溪和雷州等蔗区3个植期蔗茎产量都超过120 t/hm2,含糖量都超过20 t/hm2,蔗糖分都超过16%,农艺性状和经济性状显著优于ROC22.粤糖60号在徐闻和遂溪蔗区蔗茎产量达显著性差异,含糖量和蔗糖分差异不显著,徐闻蔗区蔗茎产量和含糖量均最高,遂溪蔗区蔗糖分最高.不同植期蔗茎产量和含糖量达显著性差异,蔗糖分差异不显著,其中12月份种植蔗茎产量、含糖量和蔗糖分均最高,2月份均最低.大面积种植试验结果表明,粤糖60号适合在徐闻、雷州和遂溪等蔗区种植.

Abstract Yuetang NO.60 was bred by Guangzhou Sugarcane Industry Research Institute. It was an excellent sugarcane variety with desirable characteristics of early maturity, high cane and sugar yields, stable yield, good agronomic traits. The results of planting experiment of Yuetang NO.60 in different planting time in Xuwen, Suixi and Leizhou showed that the mean cane yield of Yuetang NO.60 was 120 t/hm2 above, sugar yield was all over 20 t/hm2, sucrose content was all exceed 16.23%, and most of agronomic characters and ecomic characters were significantly better than those of the check variety ROC22, respectively. The difference among cane yield of Yuetang NO.60 in different areas was significant while the difference among sugar and sucrose content was not significant. Cane yield and sugar yield in Xuwen were the highest while sucrose content in Suixi was the highest. The difference among the cane yield and sugar yield of Yuetang NO.60 in different planting time were highly significant while sucrose content was not significantly. Ecomic characters were the highest planted in December and the lowest was in February. The results of large area planting test indicated that Xuwen, Leizhou and Suixi were suitable for growing Yuetang NO.60.

甘蔗品种选育是中国蔗糖业持续稳定发展和提高蔗糖业国际竞争力的主要核心技术,国际糖业技师协会ISSCT统计表明,甘蔗品种改良对于糖业发展的贡献率为60%[1].近年来,广州甘蔗糖业研究所不断加强对优良甘蔗新品种选育研究力度,培育出一批粤糖系列优良品种[2],例如粤糖93-159、粤糖94-128[3]、粤糖95-168、粤糖96-86[4]、粤糖99-66[5]、粤糖00-236[6]、粤糖00-318[7]、粤糖60号（03-393）[8],粤糖系列品种已成为国内自育品种中推广面积最大的品种.粤糖60号是广州甘蔗糖业研究所科技人员利用常规杂交育种方法,历经10 a选育而成,该品种中大茎至大茎、生长快、植株高、早熟、高糖、丰产、优质、宿根性能较好、抗逆性较强、适应性广,于2011年6月通过了全国甘蔗品种鉴定委员会的鉴定[8].为了加快粤糖60号在湛江蔗区示范推广,促进湛江蔗区甘蔗品种更新换代,本试验以ROC22为对照,研究了粤糖60号在湛江主要蔗区遂溪、雷州和徐闻3个植期栽培试验效果,以期为粤糖60号在湛江蔗区推广种植提供参考依据.
