In this article we will discuss about the process of abscission in plants, explained with the help of suitable diagrams. Abscission is a process that initiates the removal of a part of plant following the formation of a protective layer or scar tissue that prevents the entry of pathogen and protects the inner tissues from desiccation. Plants are shedding organisms. [...]
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 [...]
The below mentioned article will highlight the role of ethylene in the senescence and abscission process of plants. The term abscission is used to describe the process involved in the shedding of plant structures, such as leaves, characterized by the degradation of cell walls at the point of weakening (i.e. abscission zone). Present evidence suggests that cells surrounding the fracture [...]
