不同种茎处理对甘蔗萌芽和幼苗生长的影响
|
摘要
以不同部位、不同芽数和不同质量的甘蔗种茎为材料,分析不同种茎来源对甘蔗萌芽和幼苗生长的影响。结果表明:中部种茎萌芽出苗及幼苗生长表现最好,萌芽率和苗高分别为72.81%和46.33 cm;单芽茎的萌芽率较低,苗较矮,而三芽茎、四芽茎和多芽茎的萌芽率和苗高差异不明显。正常种茎的萌芽率与倒伏种茎的差异不显著,与绵蚜危害种茎、螟虫危害种茎和黑穗病危害种茎的差异显著;正常种茎苗高与螟虫危害种茎的差异不显著,与绵蚜危害种茎、倒伏种茎和黑穗病危害种茎的差异显著;而黑穗病危害种茎芽萌发长成的植株只有3.82%为正常植株,其他均为黑穗苗。结果说明生产上选健康的甘蔗中部或梢部茎留种,以双芽段、三芽段、四芽段或多芽段种茎种植有利于甘蔗萌芽和幼苗生长。
The effects of different parts, bud numbers and quality of cane seed stems on germination and emergence of sugarcane were observed in field in this study. The results showed that the germination and emergence of the middle seed stem of sugarcane, 72.81%, 46.33 cm, respectively, were better than the other two treatments. Meanwhile, the germinate rate of the single bud seed stemwas lower, and the height of cane seedling was shorter. There were no significant differences on germination and emergence among the three buds seed stem, four buds seed stem and many buds seed stem. Among the quality of cane seed stems, there was no significant difference on germination between the normal seed stem and fall damaged seed stem, while there were significant differences between the normal seed stem and other three treatments. In addition, there was no significant difference on the height of the seedling between normal seed stem and borers damaged seed stem, while there were significant differences between the normal seed stem and other three treatments. There were only 3.82% plants in the smut damaged seed stem emergence as the normal plants, and the others as the smut seedling. The results of this experiment could be concluded that it would benefit to germination and emergence of sugarcane when the middle seed stem and tops seed stem of healthy cane as the cane seed stem and planting with the double buds seed stem, three buds seed stem, four buds seed stem and many buds seed stem.
