Abstract
|
|
|
|
With the widespread use of micropropagation and seedling plug production for commercial purposes in horticulture, agriculture and forestry, proper methods derived from intensive research on physical and/or aerial environments aiming at cost effectiveness need to be prevalent. The growth of transplants including aseptically micropropagated plantlets and septically propagated seedlings can be optimized by using some common principles of environmental control with measurements. This article describes (1) the effect of environmental control on the growth and morphogenesis of plantlets in vitro with emphasis on the effect of CO₂ concentration, temperature. humidity, light intensity and duality, etc., (2) the effect of controlling aerial micro-environment on the growth and development of seedling plugs under artificial light with the emphasis on the effect of similar factors. Currently, environmental control in transplant production involving micropropagation and seedling plug production is a worldwide issue with the aim of improving plantlet quality and reducing high production costs.
