Abstract

ABSTRACT The purpose of this research was to study the effect of the concentration of growth inhibitor Paclobutrazol (Pbz) against the high growth of clove seedlings (Syzygium aromaticum (L.) Merryl & Perry) and get Pbz concentrations that can produce seed cloves in a relatively short (dwarf). The results showed that spraying Paclobutrazol (Pbz) with 25-100 ppm affect height growth of clove seedlings. Pbz the higher concentration applications, the shorter the length of apical segments produced shoots. In other words, the higher the concentration Pbz, the higher the emphasis on high growth of clove seedlings. Pbz emphasis on high growth of clove seedlings varied from the lowest, ie. 3.79% (25 ppm) up to the highest, ie 69.85% (100 ppm). Based on the comparison of height increment of plants sprayed with Paclobutrazol, the dose applications can be used to get the seed cloves that dwarf is a concentration of 50 to 100 ppm.

Abstract

This study aims to determine the effect of using MS media and ZPT NAA combined with several concentrations of cytokinins, namely BAP and Kinetin on somatic embryogenesis as seen from the growth of shoots of chrysanthemum (Chrysanthemum sp.). This research was conducted from June 2022 to October 2022 at the Genetics Laboratory of the Faculty of Agriculture, University of Sam Ratulangi. This study used a completely randomized design (CRD) with 7 treatments namely A (NAA 2.0 ppm); AB1 (NAA 2.0 ppm + BAP 1.0 ppm); AB2 (NAA 2.0 ppm + BAP 2.0 ppm); AB3 (NAA 2.0 ppm + BAP 3.0 ppm); AK1 (NAA 2.0 ppm + Kinetin 1.0 ppm); AK2 (NAA 2.0 ppm + Kinetin 2.0 ppm); AK3 (NAA 2.0 ppm + Kinetin 3.0 ppm). Each treatment was repeated 7 times resulting in 49 experimental units. Observational data were analyzed using the ANOVA test and continued with the 5% LSD test. The results showed that MS medium and growth regulator NAA combined with cytokinins could induce somatic embryogenesis of chrysanthemum plants, where concentrations of NAA 2.0 ppm and BAP 2.0 ppm had the best effect on the number and height of explant shoots. The concentration of NAA growth regulator at 2.0 ppm gave the highest number of roots and when combined with cytokinins it reduced the number of roots. Keywords: Growth Regulatory Substances, Somatic Embryogenesis, Chrysanthemum.
