Research on Techniques for Promoting Flowering of the Second Fruits in Off-Season Cultivation of'Shine Muscat'Grapes
摘要
Abstract
Addressing the seasonal surplus of'Shine Muscat',a prominent table grape variety cultivated in China,off-season cultivation utilizing the second fruit set is a crucial strategy to regulate market entry timing.The primary challenge in this off-season cultivation lies in inducing flowering for the second fruit set.To tackle this,our study examined four treatment combinations:chlormequat chloride(CCC)paired with 6-benzylaminopurine(6-BA),CCC paired with diethyl aminoethyl hexanoate(DA-6),mepiquat chloride(MC)paired with 6-BA,and MC paired with DA-6.These combinations were tested separately to observe their impacts on the inflorescence differentiation and flowering promotion effects of dormant buds on the main shoots and lateral shoots,as well as the prompt buds on the lateral shoots.Our findings revealed that,compared to the control,all treatments significantly enhanced the flowering rates of both dormant and prompt buds.Specifically,the flowering rate of dormant buds on main shoots surpassed 90%,and that of dormant buds on lateral shoots exceeded 80%,with no significant differences observed among the various treatments.Moreover,the flowering rate of prompt buds on lateral shoots reached over 60%,with the CCC+DA-6 treatment exhibiting the most favorable outcome,achieving a flowering rate of 94.12%.In this study,we selected different types of buds as potential fruiting branches for the second fruit set and applied various combinations of plant growth regulators to develop effective flowering promotion protocols for the second fruit set.The results have significant implications for the production of the second fruit set and maturity regulation in'Shine Muscat'grape,providing valuable guidance for optimizing off-season cultivation practices.关键词
