In this article we will discuss about the transport of growth hormones in plants. Non-Hormonal Factors: Carbon dioxide has been known for a long time to stimulate plant growth. There are at least two CO2 responses which depend on the CO2 concentrations. One is the responses to low concentrations, e.g. 0.03% and the other to much higher concentrations. The characteristics [...]
In this article, we will discuss about the transport of auxin in plants. The auxins are synthesized in growing menistematic regions of plant from where they are transported to other plant parts. The transport of auxin in plant is predominantly polar. In stems, polar transport of auxin is basipetal i.e., it takes place from apex towards base. In roots also, [...]
In this article, we will discuss about the totipotency and its relation to tissue culture studies in plants. It is now generally considered that every living cell in a plant possesses the potentially of producing an entire new plant or in other words it is totipotent. This phenomenon of capability of such a totipotent cell in generating an entire new [...]
