Abstract:

The aim is to study the introduction performance of citrus varieties in Shanghai area. In this experiment, five pomegranate varieties were introduced, namely ‘Mantouhong’ citrus, ‘Gongchuan’ citrus, ‘Mihani’ citrus, ‘Majiayou’ citrus, and citrus kumquat. Then, using these five varieties, various biological traits such as phenology and fruit quality of pomegranate, as well as stress resistance such as heat resistance and cold resistance were studied. Five varieties of citrus began to mature in succession in early October, the smallest single fruit weight was 12 g and the largest was 850 g, and the plants grew fast and strong. In addition, these five varieties had good water tolerance and heat resistance. This study is intended to provide a certain reference for the introduction of pomegranate varieties, and also provide a practical basis for the large-scale planting of citrus. Citrus resources has important role in botanical garden, which can enhance plant diversity, carry out popular science picking activities, enhance the gardening landscape, and carry out breeding and other scientific research.
