Plants are an important source of food and of valuable products for industry, agriculture and medicine. They are unique in many aspects of metabolic processes, development and reproduction. Most of these aspects can now be studied by the modern methods and technolo- gies of molecular and cellular biology. Such studies are also encouraged as to improve plant yield and quality. During the past decade research in plant sciences has demonstrated the feasibility of plant cell and tissue culture techniques as major tools in biology and agriculture. These techniques are also essential in strategies...
