摘要:
本试验以福农39号、桂柳05-136、桂柳05-129等3种甘蔗品种的健康种苗半茎种与新台糖22号未脱毒的半茎种作种苗来源,通过这些品种新植蔗农艺性状、叶绿素荧光参数、产量、品质的比较,以及次年宿根蔗发株分蘖的调查,找出健康种苗与未脱毒种苗的根本差别。试验结果表明,田间调查健康种苗新植蔗植株与宿根蔗苗期均未出现黑穗病,而在未脱毒新台糖22号的新植蔗与宿根蔗苗期生长中发现了黑穗病株。几个品种甘蔗健康种苗新植蔗的产量显著高于新台糖22号;霜冻后,桂柳05-136、桂柳05-129的叶绿素含量、Fv/Fo和Fv/Fm都高于新台糖22号,表明桂柳05-136、桂柳05-129的抗寒性优于新台糖22号。

Abstract: This experiment took healthy germchit’s half stem of three varieties of sugarcane such as Funong 39, Guiliu 05-136, Guiliu 05-129 and the half stem of ROC 22 with infected virus as the source of germchit. Through the comparison of the agronomic trait of these varieties’ new planted sugarcane, the chlorophyll fluorescence parameters, output and quality, and the investigation on the tillering and sprout of perennial root in the next year, it found out the fundamental difference between healthy germchit of new planted sugarcane and the germchit with infected virus. It was shown that no smut occurred to the new plant with healthy germchit during the seedling stage of perennial root sugarcane. The output of these varieties was higher than the output of ROC 22. After the frost, the content of chlorophyll, Fv/Fo and Fv/Fm in Guiliu 05-136 and Guiliu 05-129 were higher than ROC 22, which indicated that the cold resistance of Guiliu 05-136 and Guiliu 05-129 were superior to ROC 22.
