This study was conducted in the Wildlife Conservation Management Unit called Vivero El Manglar located in Acapulco municipality, state of Guerrero, Mexico; the aim was to assess the asexual propagation efficiency by means of vegetative material through stakes of Laguncularia racemosa propagules at the nursery. The methodological technique of rooting stakes for the asexual propagation of mangroves was used; from the mother plants, 500 stakes between 50 and 100 cm long and of 5 to 10 cm in diameter were collected. 54 % survival was obtained in the propagation by this technique, with a small yield formation of apical shoots and adventitious roots. The number of buds was compared to the number of adventitious roots by the Kendall’s Tau correlation test, obtaining a value of 0.062 and significance of p= 0.200 higher than p > 0.05, which suggests a very weak and little accepted positive correlation; which confirms with this statistical analysis that vegetative propagation through cuttings is not the most efficient for reproducing L. racemosa specimens under nursery conditions. To support the above analysis, the Friedman test was performed, with a 0.000 less than p ≤ 0.05 as significance value, observing significant differences in interaction between the two variables. The present study showed that the asexual spread of L. racemosa had a regular efficiency, which makes it necessary to continue with both asexual and sexual reproduction experiments.
