In this article we will discuss about the physiological processes associated with abscission. During the autumn leaves become yellow, black and pale and red in colour. Similarly, seasonal defoliations and the different shedding habits of the deciduous and the evergreen plants are of common occurrence. The plants may be facultative deciduous which conform to the intermediate pattern. The change in [...]
In this article we will discuss about the physiological significances of tuber and bulb formation in plants. The formation of tubers as the stem and bulb swellings of leaf base is governed mostly by the mobilization activities resulting in the storage of carbohydrates and fats thereby degrading the polarity in such organs. Most of the induction for mobilization starts in [...]
In this article we will discuss about the physiology of adventitious root formation. The process of development of adventitious roots in stem cuttings can be divided in three stages: the initiation of group of meristematic cells i.e. root initials; the differentiation of these initials into root primordia and the development and emergence of new roots including stem rupturing, formation of [...]
