不同种茎处理对甘蔗品种萌芽幼苗期抗旱性的影响

Effect on drought resistance of different cultivars of sugarcane at germination and emergence stage with different seedcane treatment methods

在控制环境条件下研究了3种种茎处理方法对不同甘蔗品种萌芽出苗和幼苗生长的影响。在本试验的干旱条件下,F172的萌芽出苗几乎不受干旱影响,而其它3个品种则明显受干旱影响。对于广西主栽品种桂糖11号和新台糖16号,剥叶不砍种处理在干旱的条件下出苗和幼苗生长相对较好。

Effect on the germination and emergence and seedling growth of different cultivars of sugarcane with three seedcane treatment methods were investigated under controlled environments.The germination and emergence of F172was not affected under the drought condition,but the other3cultivars were affected as compared with the CK.It showed a better situation of Guitang -11and Xintaitang16in emergence and young plant growth in the multiple budded seedcane without sheath treatment as compared with in both the two-budded seedcane without sheath and the multiple budded seedcane with sheath treatments.
