Physiological response of ancho pepper seeds (Capsicum annuum L.) to growth regulators. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.4, pp.829-837.  Epub 22-Mayo-2020.

The physiological attributes of pepper seeds are reduced from their development in the mother plant or as a result of physiological mechanisms that reduce germination and cause loss of vigor and viability. The objective of the present study was to evaluate the effect on the germination of ancho pepper seeds imbibed in the following treatments: KNO3 at 2%, 4% and 6%, promoter I at 0.5%, 1% and 1.5%, promoter II to 1 %, 2% and 3% and the control in distilled water. 120 seeds were weighed to submit them to each treatment for 48 h and obtain the imbibition curves. For the germination test in the laboratory, the conditioned seeds were sown between anchor paper and the evaluation was made after 21 days. The statistical analysis of data was performed in a completely randomized design, and the means were compared with the Tukey test (p≤ 0.05). The results showed that the solution of the treatments did not influence the process of imbibition of the seed. The highest percentage of germination was obtained with seeds imbibed in promoter I to 1.5% that reached 90% of germination, 56% more in comparison with the control that was 34%. The promoter I for its content of aminoacids, vitamins, macro and micronutrients, acted as a stimulator of germination.
