摘要:

为了研究不同中间砧对媛小春柑橘生长和光合特性的影响,以温州蜜柑、沃柑和冰糖橙为中间砧,媛小春为接穗,分析了不同中间砧对接穗生长特性、光合色素含量、比叶重和光合特性的影响。结果表明,不同中间砧对接穗保存率的影响差异明显,表现为冰糖橙>沃柑>温州蜜柑;以冰糖橙为中间砧嫁接的媛小春生长较旺盛,新梢粗度与中间砧粗度的比值最小,比叶重随时间变化较小且各时期含量相对较低,叶片具有较高的PnGs和较低的Ls;沃柑为中间砧嫁接的接穗叶片Chl a、Chl b、Car和Chl(a+b)含量较高,Chl a/b较低;沃柑为中间砧嫁接的接穗叶片拥有较高的Fo和较低的Fv/Fo。因此,不同砧穗组合对媛小春柑橘生长及光合特性的影响不同,且以冰糖橙为中间砧表现较好。

Abstract:

In order to study the effect of different interstocks on the growth and photosynthetic characteristics of Yuanxiaochun citrus, Citrus unshiu Marc., Orah and Citrus sinensis Osbeck were used as the interstock material, and Yuanxiaochun as scion. The effects of different interstocks on the survival rate, growth characteristics, photosynthetic pigment content, specific leaf weight(SLW) and photosynthetic characteristics of scion were analyzed. The results showed that the effect of the interstock on the preservation rate of scion was obvious, and it was expressed as Citrus sinensis Osbeck>Orah>Citrus unshiu Marc. The growth of the scion grafted by Citrus sinensis Osbeck as the interstock was relatively strong, and the ratio of the roughness of the new shoot and the roughness of the interstock was the smallest, and the SLW of the leaves changed little with time, and the content in each period was relatively low, and the leaves had higher Pn, Gs and lower Ls. The content of Chl a, Chl b, Car and Chl(a+b) in the leaves grafted by Orah was higher, and the Chl a/b was lower. The treatment by Orah had higher Fo and lower Fv/Fo. Therefore, different stionic combinations have different effects on the growth and photosynthetic characteristics of Yuanxiaochun citrus, and Citrus Sinensis Osbeck as interstock' performance is better.

Key words: interstock, Yuanxiaochun, growth characteristic, photosynthetic characteristic
