Abstract
Scions collected from one-year old hybrid seedlings were grafted onto 5-year-old trees of Gold-Nijisseiki cultivar,the changes in growth and photosynthetic capabilities of the scions were investigated. The result showed that top grafting significantly increased growth vigor,photosynthetic rate,stomatal conductance and intercellular CO2 concentration as well. Compared with top grafted trees,the scion seedlings had higher non-photochemical quenching(qN),but had lower maximum fluorescence(Fm),photochemical quenching(qP) and Yield. Therefore,it can be safely concluded that the reason that top grafting shortening the juvenile period is mainly due to the enhancement in light energy conversion efficiency and photosynthetic efficiency.
