摘要
研究64份芒果品种资源叶片碳稳定性同位素(δ13C)和比叶面积(SLA)的差异。结果表明,芒果品种间叶片δ13C、SLA差异均显著。叶片δ13C的变化范围为-29.31‰～-26.50‰,平均值为-27.90‰,最高品种为桂热82,最低品种为粤西1号;叶片SLA的变化范围为57.16～132.61 cm2/g,平均值为97.67 cm2/g。δ13C和SLA之间相关性不显著。
The differences of leaf carbon isotope composition （δ^13C） and special leaf area （SLA） of 64 mango varieties were studied. The results demonstrated that significant differences were found in δ^13C and SLA. Leaf δ^13C ranges from -29.31‰-26.50‰, with a mean value of -27.90‰. Guire 82 had the highest leaf δ^13C, whereas Yuexi No.1 had the lowest leaf δ^13C. SLA ranged from 57.16-132.61 cm^2/g, with a mean of 97.67 cm^2/g. However, δ^13C was not correlated with SLA.
