Abstract: Research on Performance of Newhall navel orange highly grafted on red tangerine/Robertson 36(TA)、trifoliate/Jincheng(TB)、trifoliate/Guoqing No. 1(CK) (3 kinds of combination of rootstock/interstock) and its causing by doing field experiment. The results indicated the following: TA’s growth was the most flourishing. TA had lower yields with worse integrated fruit quality than CK and TA; The tendency of the yield difference between TB and CK made difference in the different years, and the fruit quality of CK and TB had advantages and disadvantages respectively in two years. The photosynthesis ability revealed by the concentrations and the related constitute of photosynthesis pigments turned stronger and stronger in turns of TA and TB and CK. The total of soluble sugar of TA’s leaf was lower than that of CK and TB, and that of TB and CK made no notably difference each other. The various kinds of combination of rootstocks /interstocks remarkably affected the concentrations of the 8 kinds of mineral nutrients, and the tendency of the difference of all kinds of mineral nutrients’ concentrations except N and Mg’s were inconstant in two years, but the both of Fe and Mn, K and Ca, Ca and Zn indicated negative correlation and the both of K and Zn showed positive correlation constantly every year in two years.
