Cytokinins

Cytokinins: Biosynthesis and Uses discusses ornamental pot plant productivity, which is negatively affected by the pot root restriction during both the nursery and post-transplant stages. Root restriction is a physical stress imposed on the root system when plants are grown in small containers, which leads to a pronounced decrease in root and shoot growth at both the transplant and pot stages. Next, the authors summarize most information available on the main environmental and hormonal factors that affect New Guinea Impatiens plant growth under commercial conditions and shows the high potentiality of exogenous cytokinin application in both the vegetative propagation industry and pot culture of ornamental plants. The closing chapter addresses how understanding plant responses to hormonal manipulation and the physiological mechanisms involved in transplantation will allow for reaching higher commercial yields in different vegetables.
