| 摘 要： | 目的]了解在埃及两个不同地区种植的4个有潜力甘蔗品种的最佳收获期.方法]于2009~2010、2010~2011年度分别在埃及卢克索省El-Mattana研究站(上埃及)和米尼亚省Mallawi研究站(中埃及)进行了两个田间试验,采用裂区设计,3个重复,对4个有潜力的甘蔗品种G95-21、G98-28、G99-160和G99-103的新植蔗分别在不同时间,即(植后)10、11、12和13个月收获,并分别调查农艺性状、甘蔗产量和糖产量.结果]在(植后)13个月收获时,甘蔗品种G99-103和G95-21的茎高、茎径、茎重、蔗糖分、蔗汁纯度、出糖率、蔗产量以及糖产量最高,且以在卢克索省种植的甘蔗大部分农艺性状表现更优.品种、收获期和种植地点的第一和第二交互顺序显著影响所有甘蔗的农艺性状.结论]在埃及中上部地区种植甘蔗品种G99-103和G95-2,且在12和13个月株龄时收获,可以获得最高的蔗茎产量和糖产量.

| Abstract: | Objectives]The experiments were conducted to find out the optimum harvesting age of four promising sugarcane varieties cultivated at two different locations of Egypt.Methods]Two field experiments were conducted at two different locations,viz.,El-Mattana Research Station,Luxor Governorate(Upper Egypt) and Mallawi Research Station,Minia Governorate(Middle Egypt) during 2009/2010 and 2010/2011 crop seasons as plant cane to study the harvesting age,i.e.,10,11,12 and 13 months of four promising sugarcane varieties,viz.,G95-21,G98-28,G99-160 and G99-103 in a split-plot design with three replicates.The agronomic characteristics and yield of sugarcane and sugar were investigated.Result]Results showed that at 13 month harvesting age,the varieties G99-103 and G95-21 recorded highest stalk height,diameter and weight,sucrose,purity,sugar recovery,cane yield as well as sugar yield.It was observed that planting cane at Luxor governorate had pronounced positive effects on most of the studied traits.First and second interaction order among the three variables,i.e.,varieties,harvesting date and locations,significantly affected all studied traits.Conclusion]It could be concluded that planting sugarcane varieties G99-103 and G95-21 in upper and middle Egypt areas and harvesting them at 12 and 13 months stage results in highest cane and sugar yields. |
