Germination acceleration In Dalbergia retusa var. Cuscatlanica and Dalbergia Calderonii, applyinggrowth Hormones, Mycorrhiza and water treatments

Abstract

The present investigation has as purpose determine the effect on seed germination of forest species D. retusa var. cuscatlanica and D. calderonii, by using hormone, mycorrhizal and water treatments compa-red to a control sample, and verifying their efficacy for the propagation of the species under study. The variables evaluated in the process are: germination rate, germination speed, stem height, and root len-gth. In the case of the germinated seeds variable, a germination pre-evaluation was developed, conti-nuing with the analysis standards of the International Seed Testing Association (ISTA). The results expressed in Chapter VI indicate that there is no significant diffe-rence between the treatments and most of the variables; having a 95 % reliability percentage, obtaining in the germination rate (TG) 0.963247038> 0.05, in the root length 0.457387442> 0.05, and Height 0.615186075> 0.05, in the case of the germination speed we have a result of 0.01827807 <0.05 in which it expresses that the Water treatment is more effective in accelerating germination in both species than the other treatments
