Viability tests of pollens from male, gynomonoecious (GyM) and AgNO
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.
