Seedlessness is a desirable characteristic in citrus fruits sold for fresh consumption. Gamma irradiation is widely used to obtain seedless citrus fruits. Here, different clones of the self-incompatible parthenocarpic “Moncada” mandarin, obtained by gamma irradiation, were studied to assess seedlessness, pollen germination, fruit characteristics and quality attributes. Findings indicate that ir...

Air temperatures of greater than 35 ∞ C are frequently encountered in groundnut-growing regions, especially in the semi-arid tropics. Such extreme temperatures are likely to increase in frequency under future predicted climates. High air temperatures result in failure of peg and pod set due to lower pollen viability. The response of pollen germination and pollen tube growth to temperature was q...

In this study, microspore formation (microsporogenesis), gamete (microgametogenesis), and pollen features of Silene sangaria, a species endemic to Turkey, was examined cytoembryologically histochemically. The is distributed along the Black Sea coast Turkey. materials were collected from Igneada village (Kirklareli province). anthers, separated by size, passed through ethyl alcohol concentration...

Approximately 80 % of angiosperm species produce hermaphroditic flowers, which face the problem of male-male sexual interference (one or more anthers gets in the way of disseminating pollen from other anthers) or male-female sexual interference (the pistil interferes with disseminating pollen from the anthers by preventing the anther from touching a pollinator, or the anther prevents pollinator...
