Abstract
Pinching and dormancy breaking chemicals (DBC) application are potentially used to regulate the growth of plant. This study aims to evaluate the growth response of ‘Crystal’ guava (Psidium guajava L.) seedling in response to pinching and DBC application. This experiment was carried out in the Integrated Field Laboratory, Faculty of Agriculture, Universitas Lampung from March to June 2021, with a randomized completely block design (RCBD) with 2 factors (pinching and DBC) and repeated four times. The results showed that pinching could reduce the increase of height of guava seedling. The combination of pinching with DBC could significantly increase the number of new emerging leaves, branches, and shoots as well as the length of new shoots. The leaf area on new emerging leaves was not affected by pinching and DBC factors. The application of DBC to non-pinched plants inhibited vegetative growth and precisely increased generative growth, as indicated by the increase of the number of flowers produced. The most recommended treatment to improve the vegetative growth of guava plant seedlings was a combination of pinching and KNO3 40 g L-1. Keywords: 'Crystal' guava, KNO3, vegetative growth, pinching, dormancy breaking chemicals.
