“…The presence frequency (Table 2) and amount (Table 3) of gibberellins A 1 , A 4 and A 7 during the seed imbibition time may reflect the importance of these hormones in the process of seed germination as has been proposed by several authors [3,13,14,15]. It is well established that when exogenous GA 4 and GA 7 are applied, both hormones promote seed germination in tomato, pepper and several other crops [3,6,16]. GA 1 has also been reported as seed germination promoter in various horticultural species [16,7].…”

“…The identification of gibberellins A 1 , A 4 , A 7 , A 9 , A 15 , A 17 and A 44 in habanero pepper seeds (Table 1, Fig 3) may contribute to enrich the possible role of these hormones in seed germination.

“…GA 1 has also been reported as seed germination promoter in various horticultural species [16,7]. These three hormones move throughout different plant organs whereas GAs A 9 , A 15 , A 17 and A 44 are classified as biological inactive hormones [3,8,13,14,15]. On the basis of results obtained in this research and previous data [14,17], it is possible to speculate as to which degree gibberellins may be involved in the germination process of habanero seeds.…”

“…The possible involvement of endogenous cytokinins in the process of seed germination in habanero pepper is not well documented. The use of exogenous cytokinins provoked promotion in seed germination and fruit growth in jalapeño and habanero pepper [3,21,22]. Aremu et al [23], reported the beneficial effects in yield and fruit quality when exogenous cytokinins are applied to several fruit crops.…”

“…Among them; seed germination treatment is a crucial approach towards meeting that goal. The use of exogenous hormones has proven to promote seed germination in habanero and other vegetable crops [3]. Gibberellic acid is frequently used in the range of 40-100 mgL -1 to increase germination in jalapeño pepper [2] and in Golden Delicious apple seeds [4].…”

Aims: Habanero pepper (Capsicum annuum L.) cultivation is growing worldwide, mainly as a result of its high demand and nutritive contribution to human society. The presence of endogenous gibberellins and cytokinins in seeds of various vegetable crops has been related to a good germination; however, little is known on habanero pepper. The aim of this study was to search for the presence, identification and amount of gibberellins and cytokinins in seeds of habanero pepper cv “Jaguar”. Study design: Laboratory analysis for gibberellins and cytokinins were organized in solvent solutions groups with three technical replicates using a complete randomized design and results when applicable were analyzed using the statistical program 'RStudio' (version 10) and data obtained subjected to a comparison of means with the Tukey (P≤0.05) test. Place and duration of study: The experiment was conducted at the Department of Horticulture in Universidad Autónoma Agraria Antonio Narro, Saltillo, Mexico, during 2020-2021. Methodology: Lots of 50 grams dry weight of “Jaguar” habanero pepper seed samples were freeze dried and prepared with several organic solvents for the extraction, purification and identification of gibberellins and cytokinins using the techniques of GC-MS and GCMS-SIM respectively. Results: Gibberellins A1, A4, A7, A9, A15, A17 and A44 were found in habanero seed tissue. The cytokinins zeatin and zeatin-riboside were also detected in analyzed habanero samples. Conclusion: The endogenous gibberellins A1, A4, A7, A9, A15, A17, A44, and the cytokinins zeatin and zeatin-riboside are present in habanero pepper cv “Jaguar” contributing to an improve seed viability, ensuring health and overall plant yield.
