Effect of Paclobutrazol on Leaf and Clove (Syzygium aromaticum) Flowering

Abstract

The purpose of this study was to ascertain paclobutrazol’s impact on clove flowering and leaves. The study was carried out in Talaga Jaya, South Wasile, and East Halmahera between April 2019 and June 2020. On 7-year-old clove trees, the study used a randomized block design with five dosages of paclobutrazol (6 ml, 8 ml, 10 ml, 12 ml, and 14 ml) and a control (0 ml). On each tree, a 1 m2 area was examined to determine the amount of eugenol, gibberellin acid (GA), abscisic acid (ABA), chlorophyll, and leaf thickness and blister blight. On the other hand, primordial blossoming of cloves was noted. The findings revealed that while 8 ml of paclobutrazol could lessen blister blight, 14 ml of paclobutrazol boosted leaf thickness and chlorophyll content. Paclobutrazol extension at higher doses can boost ABA and quicken generative development. From December 2019 until June 2020, the primordial phase lasts until the blossoming phase. Except for the control plant, which demonstrated the impact of paclobutrazol on the flowering process, flowering persisted in the paclobutrazol-treated plants.
