Etiketle | Özet: | Germplasm constitutes the plants’ genetic basis and is used to conserve and create new crop varieties or restore genetic diversity in ecosystems. Thus, each plant origin has its own genetic characteristics, adapted to the environmental conditions in which they grow. Therefore, the conservation of biodiversity and the sustainable development of renewable natural resources depend on preserving different plant sources. Caesalpinia spinosa (Molina) Kuntze is a multipurpose species of economic, social and environmental importance, which is why a plantation with four origins (Loja, Catamayo, Paltas and Gonzanamá) was established in Quinta Experimental Punzara, using linear design at different spacings, in order to determine forestry and constitute the genetic basis of the species. The plantation was monitored for 6 months, where survival (SOB), total height (HT), base diameter (DB), and average crown diameter (DMC) of the plants were evaluated by origin. The survival rate was 94.05%, which indicated a high adaptation of the plants to the environment, however, there was no significant increase in HT (1.45 to 1.85 cm) and DB (0.12 and 0.13 cm). Caesalpinia spinosa has a high survival rate at 6 months of age, confirming its adaptability to the study area. In addition, the different origins showed genetic variability, high heritability and precision in the values obtained, aspects that are significant for future research and selection programs for the species. As for the initial growth of the individuals, it was observed that it was slow and no significant differences were found between the variables measured or between the origins, nor was the influence of the planting design identified due to the age of the seedlings. |
