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 [...]
