The effects of medium modification on in vitro seed germination and callus induction in tomato
Tomato is one of the most important vegetable and it is part of human daily food. High world population growth rate demands to increase the tomato productivity. Tomato is chosen among the researchers due to its high anti-oxidant and mineral properties. In the present study, in vitro response of toma...

In the present study, in vitro response of tomato c.v. Rio Grande was investigated.

Tomato is one of the most important vegetable and it is part of human daily food. High world population growth rate demands to increase the tomato productivity. Tomato is chosen among the researchers due to its high anti-oxidant and mineral properties. In the present study, in vitro response of tomato c.v. Rio Grande was investigated. It was found that when sucrose was used as the source of carbon, the highest germination frequency of 85% was achieved in modified N6 whereas the highest germination rate in modified 2N6 medium was 15.6.
