Abstract:
... Apples are very susceptible to infections from various fungal pathogens during the growing season due to prolonged exposure to environmental influences in the field. Therefore, a strict and targeted fungicide strategy is essential to protect fruit and trees. Increased environmental and health concerns and pathogen resistance have resulted in a rising demand to reduce fungicide usage and residues o ...
... Combined spraying of gibberellin (GA) and prohydrojasmon (PDJ) was an effective method to prevent the physiological disorder of peel puffing in citrus fruit. However, the GA and PDJ combined treatment inhibited carotenoid biosynthesis during the fruit ripening process, which led to the mature fruit with poor color. In the present study, to improve the coloration of the GA and PDJ-treated fruit, th ...
