Capacidad productiva de cepas nativas de <i>Pleurotus djamor</i> en Veracruz, México

Imported strains and substrates in the conventional cultivation Pleurotus spp. in Mexico can be substituted by local inputs, which are easier to acquire, offer sustainability in the face of climate change and high productive potential. The mycelial growth rate (MGR) and productivity of wild strains of Pleurotus djamor on substrates from the central region of the state of Veracruz were evaluated using a completely randomized desing. MXLD23, MXLD24 and 598 strains were grown on: Barley Straw (BS), Sugar Cane Leaf (SCL), Arachis pintoi (AP), Corn Stover (CS), Banana Leaves (BL) and Potato Dextrose Agar (PDA). The MGR was estimated by linear regression. The Biological Efficiency (BE), Production Rate (PR), Yield (Y), Total Fresh Weight of Sporomes (TFWS) and Production Cycle (PC) were determined. Test were performed: Shapiro-Wilks, analysis of variance, Tukey´s mean contrast, Kruskal-Wallis, and principal components analysis. On average, the MGR of strains MXLD23, MXLD24 and 598 developed in CS and BL ranged from 1.1 to 1.2 cm day-1. Intermediate values of 0.6 to 0.8 cm day-1 were observed on AP and low values on BS with 0.3 to 0.4 cm day-1. Strain 598 grown on CS showed a BE of 74%, PR of 2.17 % day-1, Y of 7.59 % and TFWS of 240 g. Strain 598 cultivated in CS has high productive potential and could be introduced in the Pleurotus production system in Veracruz.
