Time-Space Flowering and Podding Characterization in Erect-growing Summer Mung Bean（Vigna radiate L.）

The flowering and podding sequences and patterns in different Mung bean varieties were studied by examining the flowering and podding of Xilv 1 and Anlv 7, in order to provide a basis for Mung bean hybridization and high efficiency production. It was shown that the flower period of Mung bean could be divided into initial, full bloom, final stages, and secondary full bloom and final stages. Flowers mainly distributed at nodes 6-8 at the initial flowering stage; distributed at all plant nodes, especially at the nodes on lower branches at the full bloom stage; and sporadically distributed at the final flowering stage. The flowering sequence of Mung bean was that they began to flower on the first inflorescences developed from axillary buds and then flowered first at proximal nodes on lower branches, then at nodes on relatively upper branches, and finally at nodes on top branches. There were the highest numbers of open flowers and fructifying pods on lower branches, followed first by those on relatively upper branches and finally by those on top branches.
