Fenologi Perkembangan Bunga dan Buah serta Karakterisasi pada Beberapa Jenis Lotus (Nelumbo Nucifera Gaertn.) di Universitas Sumatera Utara

Abstract

Lotus is a perennial aquatic plant, where this plant belongs to the subfamily Nelumbonaceae which consists of one genus Nelumbo. The naturally occurring process of flower growth is studied in flowering phenology. Meanwhile, characterization aims to determine the characteristics or characteristics of the relevant varieties. Using the phenology of flower and fruit development as the basis for plant breeding, this study aims to explain the growth phase of flowers in several types of lotus. This research will be carried out in the greenhouse of the Faculty of Agriculture, University of North Sumatra with an altitude of ±25 meters above sea level in January 2025 to June 2025. The research was carried out using descriptive methods and observation of the development of flowers and fruits. The observation involved 2 types of lotus plants, namely pink and multicolored types. Lotus plants take 12-14 days to complete their flowering process and it takes 3-4 days to enter the fertilization process once the flowers are fully blooming. Characterization in Lotus plants varies in each sample observed.
