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
