以桂糖 11号和新台糖 16号作试验材料 ,分剥叶砍种、剥叶不砍种、不剥叶不砍种三种砍种处理。试验结果表明 :在干旱条件下 ,桂糖 11号剥叶不砍种处理的出苗率高 ,死亡率低 ,不剥叶不砍种处理株高和绿叶数数值最大。在生理生化方面 ,干旱区桂糖 11号各处理萌芽期间 ,种茎中氨基酸含量 14.2 5～ 18.0 0 mg/ g,还原糖含量 1.0 6～ 2 .58mg/ g,新台糖 16号干旱区各处理则相反 ,种茎中氨基酸含量 1.50～ 2 .63mg/ g,还原糖含量达 18.75～ 2 9.53mg/ g,种茎近于中度胁迫 ;桂糖 11号干旱区剥叶不砍种、不剥叶不砍种的自然饱和亏缺值与非干旱区各处理基本相同 ,而 ROC16的则比对照大大提高。因此 ,丘陵坡地应选用桂糖 11号剥叶不砍种技术
Gui sugar No. 11 and a new set of sugar No. 16 for the test material, cut off the leaves of seed stripping, stripping leaves do not cut species, do not strip the leaves do not cut three kinds of chopped cut. The results showed that under the drought conditions, Guitang No.11 stripping leaves did not cut the seedlings with high germination rate and low mortality rate, and did not cut the leaves without cutting. Physiological and biochemical aspects, during the budding period of Guitang 11 in arid area, the amino acid content in stems was 14.2 5 ~ 18.0 mg / g and the content of reducing sugar was 1.0 6 ~ 2.58 mg / g. On the contrary, the content of amino acids in seedling stems was 1.50-2.63mg / g and the content of reducing sugar was 18.75-2.953mg / g, and the stems were near to medium stress. The natural saturation deficit of non-cut leaves was almost the same as that of non-arid areas, while ROC16 was greatly increased compared with the control. Therefore, hilly slopes should be used Gui sugar No. 11 stripping leaves not cutting technology
