Tomato (Solanum lycopersicum L.) is a most popular and economically
important vegetable in the world. The popularity of tomato among consumers
has made it an important source of vitamins A and C in diets. The growth of
fleshy fruits like tomato fruit involves many physiological processes including
fertilization followed by pollination, cell division and cell expansion. Some
research works has been done elsewhere in the world and they reported that cell
division is continued in the fruit ovary for 7-10 days after fertilization,
thereafter, fruit is enlarged in the next several weeks by cell expansion (Mapelli
et al., 1978; Bohner and Bangerth, 1988). But it is still debatable that until what
time after cell division, cell expansions become the key factor for fruit growth
