“…The rate of pollen tube growth in the style is affected by many factors such as soil fertility and fertilization regimes (Williams, 1965), flowering dates (Church and Williams, 1983) temperature and relative humidity (Williams, et al, 1984), and sexual compatibility (Stott, 1972;Spiegel Roy and Alston, 1982).…”

T HE experiments were performed using (Nour, Fedela, Spinosa clementines, Kishu seedless, Balady, and Seedless mandarins) to determine the compatibility or incompatibility as related to the number of seeds per fruit and the genetic relation between them. For two consecutive seasons (2020 and 2021), the growth of the pollen tube in the styles following self-pollination has been analyzed using a fluorescence microscope to detect incompatibility properties. According to Nour and Fedela clementine cultivars are highly incompatible, while the other four cultivars are incompatible. After receiving pollen, Nour and Fedela clementines had very low pollen tubes that reached style. On the other hand, the highest rate was in the other four cultivars. The DNA of the six cultivars of mandarin and clementine investigated in this study was very similar. Balady mandarin and seedless mandarin appear to have very high similarities, while Fedela clementine and seedless mandarin appear to be very low. RAPD-PCR showed a specific molecule related to incompatibility such as (A-18) RAPD primer, at MW 361 bp. linked to the incompatibility of Nour and Fedela clementine c.vs.

“…In most cases these differences could be explained by reference to GOT-1 genotypes. In field pollination tests (Spiegel-Roy and Alston, 1982) some cultivars with common parents do not interponi nate well. Under low temperature conditions poor pollen growth will have a significant effect on fruit set, especially if only 50% of pollen grains are compatible.…”

“…However, most workers have been unable to demonstrate a clearcut distinction between compatibility and incompatibility in apple, since environmental and physiological factors have variable effects on -299pollen tube growth (Modlibowska, 1945;Williams and Mai er, 1977;Petropoulou, 1985). It is therefore difficult to identify the S_ locus using such conventional methods as assessing apple fruit set after controlled pollination and measuring pollen tube growth in styles (Spiegel-Roy and Alston, 1982).…”
