Vedclass · Answer

(B) The viability of pollen grains is the duration for which they remain functional to germinate and produce a pollen tube. This period is highly variable and depends primarily on the environmental conditions,specifically the prevailing temperature and humidity of the atmosphere. While some pollen grains (like those of wheat and rice) lose viability within $30$ minutes of their release,others (like those of some members of Rosaceae,Leguminosae,and Solanaceae) can remain viable for months. Therefore,the correct factor influencing this duration is the prevailing temperature and humidity.
