Antitranspirants are substances applied to the plants for the purpose of reducing transpiration (water loss) without causing a significant effect on other plant processes, such as photosynthesis & growth. They have been used with some success in horticulture, especially in the ornamental industry. Continue reading What are Antitranspirants? How do they Reduce Water Loss in Plants?
The continued secondary growth of vascular cylinder in many older roots and stems exerts a pressure which results in the stretching and rupturing of the epidermis, cortex and other tissues outside the secondary phloem. To avoid such breaking of external tissues, the plant organs develop a secondary protective covering by replacing epidermis and other external tissues. This protective secondary covering (tissues) of certain plants, especially woody plants, is called Periderm. Continue reading What is Periderm in Plants?
