Abstract
This study is devoted to understanding the effect of growing season on the ethylene biosynthesis of a heat tolerant tomato cultivar Savior. Tomato grown in winter and summer were sampled from the vine from immature green, to the red ripe stage.
Additionally, harvested red ripe fruit was sampled after 6 and 12 d of storage.
Quality attributes, 1-aminocyclopropane-1-carboxylic acid (ACC) and malonylaminocyclopropane-1-carboxylic (MACC), activities of ACC oxidase (ACO) and ACC synthase (ACS) were analyzed.
Winter and summer tomato shared the same changes in physical property during fruit development, ripening and postharvest storage.
A typical climacteric behavior of ethylene production rate was observed in winter tomato, peaking at turning stage, while in summer fruit the ethylene production continuously increased until red ripe stage.
During postharvest storage, ethylene production declined in both winter and summer tomato.
The results indicate that there is somewhat difference in phenotypes including mass and acidity and in ethylene biosynthesis intermediates.
Work at the transcriptomic and proteomic level is ongoing to characterize the molecular events underpinning the ripening of Savior tomato grown in different seasons.
