Pengaturan Pembungaan pada Jambu Biji (Psidium guajava L.) 'Kristal' dengan Penggunaan Paklobutrazol dan BAP

Abstract

Guava plant 'Crystal' is a horticultural commodity that can produce fruit throughout the year, but the availability of fruit must be maintained. In maintaining the continuity of the availability of the fruit, an alternative is needed to regulate the flowering of 'Crystal' guava plants in order to meet market demand. This can be done by giving Growth Regulators (ZPT) such as Paklobutrazol and Benzyl Amino Purines (BAP). This study aims to determine (1) the effect of Paklobutrazol in increasing the flowering of 'Kristal' guava plants, (2) the effect of BAP on increasing the flowering of 'Crystal' guava plants, and (3) the effect of the interaction of the best treatment between Paklobutrazol and BAP in increasing flowering. guava plant 'Crystal'. The method used in this study was factorial Randomized Block Design (RAK) with two treatment factors which included the administration of Paklobutrazole (P) with three levels and the treatment factor of giving BAP (N) with three levels. The results showed that 1) Paklobutrazol treatment with a concentration of 8,000 ppm increased the number of generative shoot variables, the number of blooms, the number of ovules, the number of fruits, and the weight of the fruit; 2) administration of 100 ppm BAP increased the number of vegetative shoots and number of leaves; 3) the treatment between Paklobutrazol and BAP only occurred in the variable number of vegetative shoots, the highest was produced by the 100 ppm BAP and 100 ppm Paklobutrazole treatments, namely 160 vegetative shoots.. Keywords: paclobutrazole, 'Crystal' guava, and BAP
