Investigation of Morphological and Biochemical traits of six
cherry tomatoes lines (Solanum Lycopersicon Var. cerasiforme)
By Mozhgan Khedri
Cherry tomato or miniature tomato (Solanum Lycopersicon Var. cerasiforme) is one
of the most important economic tomato species in the world. Quantitative and
qualitative traits of this fruit can be affected by the lines genotype, environment and
type of plant cultivation. Therefore, the purpose of the research is to investigate the
fruit quality characteristics of six lines of cherry tomatoes (yellow pear, red pear,
big red orbicular, small yellow orbicular, red olive and yellow lump) under two
different cultivation conditions and the interaction of traits withe cultivation
environment.
The results of analyses of variances showed that the simple effect of line, type of
cultivation method and also the interaction of line in cultivation on fruit weight and
volume, plant length, percent of flower fruit setting, plant yield, soluble solids,
carotenoid, lycopene, vitamin C and citric acid of cherry tomato fruit had
statistically effect (p ≤ %1).
According to the results of morphological characters, the highest weight fruit (24.5
gr), volume fruit (256 m3
) and plant yield (2883.25) were in the big red orbicular
line of cherry tomatoes cultivated in hydroponics. The highest precent of flowers
fruit setting (98.75%) was in the highest plant yield (2883.25 gr) was in the big red
orbicular line in hydroponic cultivation. about biochemical characters, the highest
amount of lycopene was in the red olive line (13.75 mg/100gr) in soil cultivation,
the highest amount of carotenoid was in the big red orbicular line (7.64 mg/100gr)
in soil cultivation and the most of citric acid was in the small yellow orbicular line
(10.3 mg/100gr) in soil cultivation. The most TSS (12.3 0Brix) in the small yellow
orbicular line of cherry tomatoes cultivated in hydroponic and the highest amount
of vitamin C was in the red pear line and hydroponic cultivation
