Concerning with the propagation of such superior peach rootstocks containing the rootstocks which are resistant to root-knot species of nematode, the propagation by cuttings would be expected as available method. In this study, some experiments were made to obtain the fundamental informations for cuttings of peach. Among all seasons tried, the rooting ability was high in cuttings planted in June and in December-January, and it was also found that C/N ratio was high in scion of peach at the same season. The total carbohydrate contents in scion generally decreased according as storage continued, especially starch contents remarkable. The decrease in total carbohydrate contents was affected more markedly by refrigeration than by stratification with sand. The nitrogen contents remained relatively constant during planting period, though with some increase at the latter term. A rooting of 65.0% and 58.8% was obtained with 'Okubo' and 'Hakuto' cuttings respectively. In contrast, none of 'Hakuho' cuttings produced roots. High percentage of the sprouting in 'Hakuho' cuttings was observed at the first stage of planting period. It seems tendentious that C/N ratio in basal stem of cuttings showed higher value than in upper stem. Comparing with rooted 'Okubo', 'Hakuto' and non-rooted 'Hakuho', the latter had less C/N ratio.}, pages = {8--16}, title = {モモのさし木繁殖に関する基礎的研究 I : 体内養分と発根との関係(農学部門)}, volume = {29}, year = {1977}, yomi = {ゲンマ, ヒロシ and ウジモト, ヨシタカ and ソバジマ, ヨシツグ} }
