Khảo sát chất lượng của cây Dã yên thảo (Petunia hydrida) qua các thế hệ cành giâm

Abstract

This study aims to determine the number generations of cuttings that can be used as seeds while ensuring the growth, development and quality of petunia hydrida. After completing the experiment concentration of NAA and the number of cuttings generations in petunia hydrida, the results when cuttings of petunia hydrida with a concentration of 1,500 ppm NAA gave the number of roots (59.62 roots), root length (6.84 cm), rooting rate (75%) and outplanting rate (74.1%) were high for all cuttings generations. The experiment examining the quality of petunia over cuttings showed that leaf length, leaf width, and flower strength of each generation were the same and not different from seed plants. The number of shoots / plant, the number of leaves / plant, the flower diameter and the number of flowers per tree planted from seeds and plants of generations 1st and 2nd are higher than those of the 3rd and 4th generation, the flowering time of petunia hydrida plants in 4th generation earlier than the rest. Experimental results are that it is possible to use cuttings from generation 1st to generation 2nd as seedlings for production, while ensuring the quality of plants and petunia hydrida when planting.
