Abstract

Tomato cultivars with different sensitivity to
high temperature (Campbell-28 and Amalia) and the wild type
Nagcarlang, were exposed to different stress conditions (450Ctwo
hours of exposition, 450C-three hours of exposition and
250C as control). �??a�?�, �??b�?� and total chlorophylls were
determined as well as carotenoid and total soluble protein
content, and cellular viability. Chlorophyll �??a�?�/�??b�?� and
chlorophyll/carotenoid ratios were estimated. Variables
changed depending on cultivars and stress exposure time.
Taking Nagcarlang as a model of thermotolerance, variables
such as chlorophyll �??a�?�/�??b�?� ratio, chlorophyll/carotenoid ratio,
total soluble protein content and cellular viability (TTC assay)
might be useful to describe thermotolerant cultivars to high
temperature, depending on stress exposure time.
