A STUDY ON THE GROWTH AND FLOWERING OF Hippeastrum equestre Herb GROWN IN SANDY SOIL

Abstract

This paper presents the results of the growth and flowering of Hippeastrum equestre Herb grown in sandy soil. The experimental layout was conducted within an area of 10 m² and divided into 5 plots, the block-size per plot was 1.2 × 1.6 m. The results showed that the bulb’s diameter was greater than 6 cm which was suitable for the flowering. The rate of leaf development corresponded to the growth process of plants and the average leaf lengths ranged from 59.40 to 74.56 cm. The average plant heights of Hippeastrum equestre Herb ranged from 45 to 50 cm. In addition, the study carried out the drying Hippeastrum equestre Herb’s bulbs in the the various period of 10, 15, 20, 25, 30 days to observed the flowering development. The results investigated that the dried bulbs had a significant effect on flowering time and and flower development, which found the longer the drying period of bulbs and thus produced flowers sooner. The thickness, length, and width of petals of Hippeastrum equestre Herb ranged from 0.079 to 0.084 cm, 10.55 to 11.62 cm and 6.48 to 7.12 cm, respectively.
