Assessment of Four-Seasonal Quality and Yield of Cut Flower Roses Grafted onto Rosa Rootstocks

Cut roses are ornamental crops that produced year-round, and the quality yield of these cut flowers vary depending on temperature light intensity four seasons. Grafting improves productivity by increasing adaptability to negative environments, such as high low intensity. The effectiveness grafting depends type scion rootstock. In order confirm stenting roses, two varieties (Rosa hybrida cv. Pink Beauty Shine) were grafted onto three rootstocks (R. multiflora Natal Briar, R. indica Major, Rosa Hort. No. 1), which widely used in rose, investigated year-round according seasons; then, principal component analysis (PCA) was performed. (PB) showed excellent growth autumn when low. PB Briar (NA) rootstock improved spring, winter, excluding summer, had effect lengthening stem. Major (RI) also autumn, except particular, stem lengthened thickened. rosa Shine (PS) a variety whose increased summer high. PS gave higher than scion. graft PS/Natal longer stems scion, PS/Major thicker 1 (N1) more petals As such, canina brier length, relatively temperatures, length diameter, enhancing temperatures.
