Evaluation of Rubber Tree Clones Under Different Tapping Systems in Northwestern Paraná State, Brazil.

Abstract

This study evaluates the potential of rubber tree clones (Hevea spp.) under four tapping systems for the Northwestern region of the State of Paraná with the objective of enhance genetic diversification and increase natural rubber production in this new and promising region for rubber tree cultivation by selecting the better combination of clone and tapping system. The experiment was installed at Guanabara Farm, municipality of Paranapoema, Paraná State, in a split-plot randomized complete blocks experimental design with three replications.

Research trend in latex harvesting of rubber tree (Hevea brasiliensis Muell. Arg.) based on bibliographic analysis

“…A tapping system and ethylene stimulation are the main tools for obtaining latex production in rubber plantations. However, this study showed that only four of 38 analyzed papers reported modification and evaluation of the suitability of the tapping system (Padjung et al, 2020;Pereira et al, 2018;Purwaningrum et al, 2019;Rukkhun et al, 2021 and five studies on ethylene stimulation (Attanayake et al, 2018;Long et al, 2018;Purwaningrum et al, 2019;Yunta & Dede, 2019;and Budiasih et al, 2020) Although much research has been published in these two fields, most of them were in journals unrecognized by Scopus. This suggests that research on these topics requires additional data such as LD and molecular analysis for a better explanation of the effect of tapping and stimulation.…”

“…Arg.) basada en análisis bibliográfico May -August 2022 164 machines were frequently reported (Deepthi et al, 2020;Zhang et al, 2019;Zhang et al, 2018. Although research on tapping systems was still conducted, for example, studies by Long et al (2018), Pereira et al (2018), andBudiasih et al (2020). This typical work was rarely published in Scopus-indexed journals in the last two years (2021 -2022).…”
