摘  要:
以'黑比诺'葡萄试管苗为试材,研究了1000μmol/mol CO2浓度下3种不同外源蔗糖、果糖、葡萄糖对葡萄试管苗生长和光合特性的影响.结果表明:高CO2浓度下葡萄糖处理显著提高试管苗出愈率、根和茎生长速度.与其他两类糖处理相比,出愈率分别平均提高5.8%、8.6%,根生长速度分别平均提高0.54 cm、1.02 cm,茎生长速度分别平均提高0.93 cm、1.59 cm,葡萄糖处理可以明显促进植株的生长与光合作用;高CO2浓度导致果糖处理叶绿素相对含量较正常浓度升高.

摘  要:
The effects of three different exogenous sucrose,fructose and glucose on the growth and photosynthetic characteristics of'Pinot Noir'grapevine plantlets under 1000μmol/mol CO_2 concentration were studied.The results showed that the callus rate,root and stem growth rate of test-tube seedlings were significantly increased by increasing glucose application at high CO_2 concentration.Compared with other two sugar treatments,the callus rate increased by 5.8%and 8.6%,root growth rate increased by 0.54 cm and 1.02 cm,stem growth rate increased by 0.93 cm and 1.59 cm,respectively.Glucose treatment could significantly promote plant growth and photosynthesis.High CO_2 concentration led to higher chlorophyll content in fructose treatment than normal concentration.
