Question

State two factors that control the germination of a pollen grain

Answer 1

Answer:

Temperature, PH, Sucrose, Boric acid, Calcium

Explanation:

Boron is only one factor that can markedly affect pollen growth. Potassium and sodium at concentrations of 0·01 M and barium and magnesium at 0·0015 M inhibit pollen germination [24]. Brink [24] found that calcium at 0·05 M enhances pollen growth.
