Effects of Low-Temperature Accumulation on Flowering of Prunus mume

Low-temperature accumulation is one of the essential stages in growth process woody ornamental plants. In this study, two different low-temperature treatments, 6 °C and 10 °C, were used to analyze effects treatments on dormancy release flowering ‘Gulihong’ plant using artificial low temperatures. Based experimental results, four typical early-blooming Prunus mume cultivars widely planted Yangling area Henan Province, China, including ‘Zaoyudie’, ‘Zaohualve’, ‘Nanjing gongfen’, ‘Gulihong’, selected as materials. The characteristics analyzed a treatment. suitable cultivation temperature for was screened provide theoretical basis further exploration P. bonsai techniques. results showed that rate, flower diameter, quantity, uniformity, bud development treatment significantly better than those Furthermore, under treatment, rate quality an increasing trend with temperature, exhibiting highest rate. Therefore, chill plays significant role promoting quality.
