This book included six papers. The first paper focuses on studying factors affecting shoot organogenesis of eight tomato genotypes and testing some tomato genotypes for salinity tolerance in vitro. The second paper concentrates on the clonal propagation in garlic plant. The third paper deals with the production of secondary products from garlic plant. The fourth paper investigates the effect of benzylaminopurine concentration and number of subcultures on behavior of some strawberry cultivars in vitro. The fourth paper investigates the field performance of micropropagated strawberry plants derived from different subcultures and media containing different benzylaminopurine concentrations, and the final one describes a protocol for the large scale production of haploid plants by unpollinated ovules culture in squash (Cucurbita pepo L.). This book will be useful for readers interested in understanding application aspects of the tissue culture techniques in the agricultural sector.
