Effects of Vernalization on Off–Season Flowering and Gene Expression in Sub-Tropical Strawberry cv. Pharachatan 80

Off-season strawberry production may diversify the yield, thereby increasing costs, but environmental conditions are a limiting factor. This experiment aimed to study effects of vernalization on off-season flowering and gene expression in sub-tropical cv. Pharachatan 80. The factorial (2 × 2) + 1 completely randomized design was used this study. Factor A temperatures: 2 °C 4 °C. B periods: week weeks, compared with non-vernalization (control). profile genes determined after treatments. results revealed an interaction between two factors number days it took plants bloom, percentage flowering, inflorescences, flowers per inflorescence plant, whereas first flower bloom days, length size were not affected by factors. Strawberry vernalized for weeks at showed earlier (21.4 23.1 respectively) than did those (24.9 25.7 respectively). On other hand, non-vernalized longer 62.2 days. had highest plant. analysis that VRN5, SOC1 FT upregulated control treatment detected. demonstrates could induce 80 activating genes.
