Study on Preservation Technology of New Rose Variety'Miyue'
'Miyue'is a new excellent variety with independent intellectual property rights,which was bred by the Flower Research Institute,Yunnan Academy of Agricultural Sciences for many years.It has red flowers,high roll cup-shaped,strong disease resistance,and an annual yield of 20 branches/plant.In order to better promote this variety,this study will screen suitable fresh-keeping as the reference in the later popularization of varieties.This study selected the commercial chrysal,oasis and self-made preservation agent for preservation experiment.The bacterial content in preservation liquid,flowering index,flower diameter,fresh weight loss rate,water balance value,dry matter content,cut flower petal pH value,preservation liquid pH value,soluble protein,superoxide dismutase and other indexes were determined.The ornamental effect of cut rose'miyue'was better in the oasis and chrysal preservation liquid,and the flowers opened normally without wilting,while the ornamental effect in water control and self-made preservation agent was not so good.The maximum flowering index of cut rose'miyue'reached on the 5th day in clean water control and oasis preservation solution,and on the 6th day in chrysal preservation solution.The openness was maintained well.The bacterial content of the control group and the self-made preservation liquid group increased with the increase of test days,and the antibacterial effect was was significantly different from that of the other two groups.The antibacterial effect of chrysal group was the best,and no bacteria were detected in the preservation solution.According to all test indicators,chrysal is still a good preservation agent,and the self-made preservation agent will be improved in the future to provide preservation technical support for the promotion of varieties in the future.
