Background
Anjiang fragrant pomelos are also called tribute pomelos, are one of citrus fruits, belong to special fruits in province of Hunan province, and are produced in Hongjiang city. In actual production, the Anjiang pomelos have more blossoms and less fruit setting, most of blossoms and young fruits fall off in the flowering period and the fruit development process, the phenomena of serious flower and fruit falling exist, the fruit setting rate is only 0.8-1.1%, and the yield is low.
The flower and fruit retention is an important means for improving the fruit setting rate of the fruit trees within the range of the load stabilizing capacity, so that the flower and fruit retention measures are implemented to reduce flower and fruit dropping and improve the fruit setting rate, and the improvement of the fruit setting rate in the years with less flowers is a key link for obtaining high yield of the fruit trees. At present, the conventional treatment technology for flower and fruit retention in actual production comprises the steps of improving the storage nutrition level of trees, properly controlling the vegetative growth, ensuring good pollination conditions, improving the environmental conditions, applying growth regulators and trace elements and the like. The flower and fruit retention drugs for citrus in the market mainly comprise 2, 4-D (2, 4-dichlorophenoxyacetic acid), cytokinin, gibberellin, paclobutrazol and other plant growth regulators and some general flower and fruit retention agents. Among them, Gibberellin (GA) is a widely existing plant hormone, regulating growth and influencing various developmental processes, and as of 2003, there are at least 126 gibberellin species and their analogous structural chemicals, which are used in the order of discovery with A1(GA1) To A126(GA126) Name of a mode. However, these drugs have a general effect on flower and fruit retention of Anjiang grapefruit.
Therefore, there is a need to develop a flower and fruit retention agent, which can improve the fruit set percentage of Anjiang pomelos.
