Other claims from this paper (10)

Intervention effect Zinc deficiency decreased the number of pods, seeds per pod and seed mass of black gram.
Intervention effect Zinc deficiency altered the seed coat topography of black gram.
Intervention effect Zinc deficiency reduced seed germinability of black gram.
Intervention effect Zinc deficiency caused structural alterations in the exine of black gram pollen.
Intervention effect Zinc deficiency retarded pollen grain germination and pollen tube growth in black gram.
Intervention effect Zinc deficiency decreased the size of anthers and stigmatic heads of black gram.
Intervention effect Zinc deficiency decreased the pollen producing capacity of anthers and stigmatic exudations of black gram.
Intervention effect Pollen extracts and stigmatic exudates of zinc-deficient black gram plants showed increased acid phosphatase isoform activity.
Intervention effect Pollen extracts and stigmatic exudates of zinc-deficient black gram plants showed inhibited esterase isoform activity.
Mechanism Low seed yield under zinc deficiency is attributed to a role of zinc in pollen function and in pollen-pistil interaction.
