Changes in Yield, Quality, and Morphology of Three Grafted Cut Roses Grown in a Greenhouse Year-Round

Cut roses are grown throughout the four distinct seasons of spring, summer, autumn, and winter in Korea. Especially very hot or cold summer winter, temperature light environments inside a greenhouse cause abiotic stress on growth horticultural crops. In where shade cultivation is performed high intensity low, whereas when not performed, both low. This experiment investigated year-round yield changes cut grafted onto three rootstocks. The root activity rootstocks was generally higher than that scion. stomata showed morphological according to seasons. Compared with scion, became smaller their number increased only size winter. had characteristics photosynthetic efficiency such as photosynthesis rate, stomatal conductance, transpiration rate from under harsh environmental conditions including intensity, thus There no significant change roses, but flower quality parameters stem height, thickness, weight were improved compared those particular, R. multiflora cv. Natal Briar Rosa indica ‘Major’ rootstocks, lengthened thickened Therefore, grafting effective improving caused by during
