Abstract:

In plants, pollution and fertilization is an important event affected by environmental factors. During the pollen grinding and pollen tube growth, the sensitivity of plants increases and the generating organs of plants are more sensitive to environmental pollution than the vegetative parts. Therefore, pollution in unsuitable conditions such as metallic toxicity and fertilization and therefore the fruit attitude are negatively affected. In this study, the effects of different heavy metal doses (Cd, Co, Pb, Hg and Zn) on pollen grinding and tube growth in Red Chief and Granny Smith apples varieties were studied.  The pollen vitality rates of species are determined by the TTC (2-3-5-triphenylethrazole chloride) vitality test and the average vitality rates are 84.4% in the Red Chief species and 75% in the Granny Smith species. 4 is determined. However, varieties have been significantly affected by the application of both heavy metals and doses. The pollen grinding and tube length of the varieties have shown a decline due to the increase in the dose of metal. In apple varieties, the highest inhibitor effect on pollen grinding and tube length has been shown by civa (Hg) and the lowest effect by kobalt (Co).
