Viability tests of pollens from male, gynomonoecious (GyM) and AgNO ₃ treated female plants. Pollens stained with 1% acetocarmine from male (A), gynomonoecious (GyM) (B) and AgNO₃ treated female (C) plants. (D), (E) and (F) are the fluorescein diacetate (FDA) stained pollens from male, gynomonoecious (GyM) and AgNO₃ treated female plants respectively. Pollens stained with acetocarmine (A) and FDA (D) are viable. Scale bars are 10 μm in A, 5 μm in B, 50 μm C, and 25 μm in D, E and F. (G) Highest germination of male pollens in 5% sucrose solution. Scale bar =50 μm. (H) Graphical representation of the germination percentage in different concentrations of sucrose solutions. Means ± standard errors are reported in the graph; n = 10.
