Which of the following is most important factor in regulation of transpiration?
Options
(a) humidity
(b) light
(c) temperature
(d) all of these
Correct Answer:
all of these
Explanation:
A number of external and internal factors influence the rate of transpiration. Among the internal factors are root/shoot ratio, leaf area and leaf structure. External or environmental factors, include
(i) Relative humidity – If R.H. is low then rate of transpiration depends upon difference in vapour pressure or internal atmosphere of leaf and external environment (i.e., V.P gradient) and it is, therefore, that no transpiration occurs when stomata are fully open but relative humidity is 100%.
(ii) Light
