New Cultivars Multiplication of Oriental Raisin Tree (Hovenia dulcis var. koreana Nakai) by Veneer Grafting

Abstract

Hovenia dulcis var. koreana Nakai, the oriental raisin tree, has been considered not only fruit but an herbal medicine in East Asia including Korea, Japan and east China. As honey plant, value of this species had been rising steadily. The aim of this study was conducted to develop the propagation technique by scion collection time, scion age and vinyl house on survival rate of H. dulcis. The survival rate by veneer grafting showed no significant differences among 3 new cultivars. The scion collection at the northern temperature zone was observed to be the most appropriate time before the spring equinox when the plants are fully dormant. Especially, the installation of vinyl house showed 86% survival rate by veneer grafting. The scion age was effective 1 year shoot than 2 years shoot for increase the grafting survival rate. In this case, the installation of vinyl house can contribute above 80%.

Antioxidant and Antibacterial Properties of Hovenia (Hovenia dulcis) Monofloral Honey Produced in South Korea

“…The Hovenia tree prefers to grow in a sunny position, and the blooming period is about 20 days from June to July. The nectar production of the Hovenia flower is higher than that of the Acacia flower (Han et al, 2018;Song et al, 2014). Thus, Hovenia trees have been considered a candidate for honey plants in South Korea.…”
