Reproductive and vegetative behavior of hybrid jabuticaba tree under flowering induction

Abstract

Brazil is one of the countries with the greatest vegetal diversity in the world, especially for the Myrtaceae family, to which the jabuticaba tree belongs. Its fruits are of great acceptability, but it is little explored commercially, because it takes a long time to reach the production stage. This study aimed to evaluate the vegetative and reproductive behavior of hybrid jabuticaba trees under flowering induction treatments. A randomized block design was used, with the following treatments: calcium carbide, etefon, paclobutrazol, daily irrigation management and control. Growth and reproductive development data were evaluated. For vegetative growth, there was no difference among the treatments, demonstrating no negative effect. On the other hand, paclobutrazol showed to be the most promising treatment, because it anticipates flowering, is effective in induction and results in a higher production.

Calcium carbide in anticipation and standardization of ripening in Cajá-manga fruits

“…Climacteric fruits such as cajá-manga, which have a peak ethylene production, can have the ripening process artificially accelerated by metabolic reactions catalyzed by acetylene, a gas similar to ethylene that simulates the physiological effect of this hormone on fruits' tissues and generates uniform maturation, and can be obtained through the exogenous application (SIQUEIRA et al, 2017). Ethylene analogs such as calcium carbide are commonly employed to promote the flowering of various fructiferous and ornamental species (KOSERA NETO et al, 2018;SOARES et al, 2022).…”

Effects of exogenous applications of gibberellic acid on the development and quality of jabuticaba fruits

“…Jabuticaba (Plinia spp.) fruits are rich in sugars, vitamins and other compounds that are beneficial to health and pleasant to the palate (Kosera Neto et al, 2018).…”
