Abstract

The objective of this research was to analyze the percentage of germination based on seedlings emergence in ten genotypes of Habanero chili pepper (Capsicum chinense Jacq.) undercontrolled conditions in San Quintin Valley, State of Baja California. Twelve hours prior to planting, the seed was treated with gibberellic acid at 40% of its concentration, this with the purpose of guaranteeing the germination and seedlings emergence. Sowing was carried out from February 21st, 2013, 2014, 2015,2017 in seed trays of polystyrene with 130 cavities, which were taken to a company dedicated to commercial production of seedlings, the seedlings emergence was registered, with which the germination of seeds was determined for each genotype. The evaluated genotypes were two commercial varieties; Yucatan Jaguar and Jaguar INIFAP, as well as experimental materials: HRA 7-1, HNY 201, HAN 1-30, HRA 1-1, HAN 25, 1-40, HQR 15-3 and 15-1 HUX. The ten genotypes treated with gibberellic acid had good response on germination and seedlings emergence under the conditions of the San Quintin Valley, State of Baja California. Statistically significant differences did not occur and it obtained an average of 98.4%, but F1 and F2 of the Spartacus hybrid seeds without being treated with the acid, had only 46% of germination, with what can be inferred that the gibberellic acid, under the conditions of San Quintin Valley, Baja California, and with management applied in the system of production of seedlings, it increases significantly the germination of seeds of habanero chili pepper.
