The objective of this study was to determine the effects of inverted radicle and hypocotyl grafting methods on potted nursery tree production in chestnut. The study was carried out in greenhouse conditions in 2003-2004. Newly germinated chestnut seeds and young seedlings of SA 5-1 genotype were used as rootstocks, sprouts with dormant buds of the same genotype were used as scions. Graftings were done at three periods from April to June. Graft success and scion shoot growth were examined to determine a suitable method and time of grafting. It was found that potted chestnut nursery trees could be produced in one year using either of the grafting methods. Better graft success and survival ratio were obtained from inverted radicle grafting than from hypocotyl grafting. When using the inverted radicle grafting, the success was 83.6% in 2003 and 96.7% in 2004.
