Green tomato fruits of different studied hybrids such as, Amal, Steel,
Tartila, and 2-75/96, which had been grown in a greenhouse at Abi- Jarash
Farm were picked up and stored at temperatures of 12 c and 20 c for 29 days.
The fruits, which were st
ored at 12 c had been transferred to 9 cْ, and then
stored for an additional period of two weeks. The chemical composition of the
stored fruits was evaluated, which included: acidity percentage, total soluble
solids, and the quantity of vitamine C. The ratio of fruit weight loss during
storage was studied as well.
Production, meiotic analysis, and description of morphological
characteristics of an intergeneric hybrids ABJ1J2 between durum wheat and
Thinopyrum junceiforme, are described. The hybrid resembled the wheatgrass.
It inherited the tillering habit,
perennial growth habit, and glaucous leaves and
stems from the wheatgrass. F1 is pollen and seed sterile, while BC1 and BC1F2
were pollen and seed fertile.
This study aimed to evaluate the F1 non ripening tomato hybrids for yield
components and some other biological and morphological traits in the green
house.
This investigation included the comparesion of six tomato hybrids during
tow years (1999,
2000). Under the green-house conditions.
It has been found significant differences among the investigated hybrids
regarding to yield, plant hight, leaves number, flowers number, and the periods
from germination to flowering, germination to ripening, and flowering to
ripening, but, there was no any significant variation in fruits number and fruit
setting rate.
