摘要
在有微喷灌条件的旱地上栽培果蔗,研究脱毒果蔗在旱地生长生理情况。结果表明:脱毒果蔗单位面积产量比未脱毒果蔗增产23.45%;脱毒果蔗叶绿素含量为2.30 mg/g,比未脱毒果蔗的1.57 mg/g提高46.62%;叶片相对含水量为102.46%.mm,比未脱毒果蔗97.97%.mm提高4.59%;脱毒果蔗伤流量为776.19 mg/h.cm2,比未脱毒的609.02 mg/h.cm2提高27.45%;脱毒果蔗单株根系鲜重135.47 g、干重79.12 g,分别比对照增加22.96%、15.02%;后期的完全展开绿叶(功能叶片)脱毒果蔗比对照多1.3片,增加20.00%;单株绿叶重脱毒果蔗0.458kg,比对照增加36.31%。
Under the micro-sprinkler irrigation condition, the growth physiological of virus-free chewing cane (VCC) cultivated in dry-land was researched. The results showed that compared to the control was not done any virus procedure, cane yield was increased 23.45%; the cane leaves chlorophyll content of VCC (2.30 mg/g) was higher than control (1.57 rag/g) by 46.62%; the leaf relative water content of VCC (102.46%mm) was higher than the control (97.97% mm) with 4.59%. The amount bleeding sap of YCC (776.19 mg/h-cm2) was over than control (609.02 mg/h-cm2) by 27.45%mg/h-cm2; the fresh and dry weight of VCC root were 135.47 g and 79.12 g, were increased 22.96% and 15.02%, compared with the control, respectively. On last growth stage, the number of completely unfold green leaves (functional leaf) of VCC was more than control by 1.3 leaves and increased with 20.00%. The green leaf weight of VCC was 0.458kg/plant higher than control with 36.31%.
