Evaluation of the development and growth of Enterolobium cyclocarpum, Maclura tinctoria under controlled conditions, Estelí -Nicaragua

Abstract

Despite the growing importance of dry tropical trees for the conservation of biodiversity, little is known about the dynamics of its behavior, such as its adaptation to different climate changes. In order to contribute to the knowledge of the dynamics of its behavior to these changes and obtain information about the conditions under which these species can develop, it was evaluated at the Experimental Station for the study of the dry tropics “Limon” the behavior in growth and development of seedlings of the species Maclura tinctoria and Enterolobium cyclocarpum; subjected to different doses of water and degree heat, contributing therefore to its recovery and conservation. It was utilized a randomized complete block design, with an adaptation to the investigation conducted by Diaz. E (2010).

The data obtained were analyzed using the non-parametric test of Kruskal-Wallis variance. None of the moisture treatments applied to Maclura tinctoria seedlings showed significant influence on diameter at root collar and height, just as happened in height to E. cyclocarpum; however, in diameter at root collar it was shown significant differences in the Cc treatment, plus 50%. Seedlings of both species exposed to room temperature (21.7 ° C) showed significant difference in diameter at root collar; and in height M. tinctoria exposed to 25.7 ° C presented difference, and E. cyclocarpum that were exposed to 30 ° C. Both species are adaptable to changes in temperature and humidity, being recommended in reforestation programs.
