“…The germination percentage found in this study was in accordance with the results of Awamura et al [22] in which caprifig pollen germination increased to above 70% by adding stigmatic exudates from long styled pistillate flowers to the culture medium. Similarly, it was showed that a low concentration of sucrose (5%) and temperature of 30 ∘ C during 24-48 hours of incubation were effective for better pollen germination [18,19].…”

The evaluation of pollen viability and its germination capacity are two essential criteria for pollinator's characterization. This study was carried out to evaluate pollen quality of eight caprifigs grown in the center-east and north-west of Tunisia. Two colorimetric tests 2,3,5-triphenyl tetrazolium chloride (TTC) and acetocarmine were used to estimate pollen viability. Germination rate and pollen tube growth in a culture medium containing 5% sucrose, 5 ppm boric acid (H 3 BO 3 ) and 1% agar were registered after 24, 48, and 72 hours (H) of incubation. Results showed that the highest pollen viability rate (84%) was obtained by TTC test in caprifig Assafri, followed by Jrani (80.2%), Djebba 2 (77.8%), and Djebba 1 (73.6%). That of other caprifigs did not exceed 50% for the two tests. In all caprifig types, germination rate and pollen tube growth varied according to the incubation period. The highest percentage of germination (72%) and maximum pollen tube length (960 m) were recorded after 72 H of incubation in caprifigs Assafri and Jrani, respectively. Among the caprifigs studied, four types (Assafri, Jrani, Djebba 1, and Djebba 2) appeared to be suitable pollinators with respect to the criteria investigated.

“…This proves the positive role of adding the extract of the longstyle female stigma flowers in raising the per centage of pollen germination of caprifig varieties and increasing the growth of the pollen tube in them. These results are consistent with several previous studies (Ilgin et al, 2007;Awamura et al, 1995), where pollen germination from caprifig was increased to more than 70% when longstyle stigmas were added to the pollen culture medium.…”

“…The germination rates of some caprifig pollen grains were higher than 70% with the addition of 0.050% H 3 BO 3 , followed by 0.025% KNO 3 , and the germination rates of caprifig pollen were higher with the addition of these chemi cals than sucrose 20% alone. Germination of caprifig pollen was increased to more than 70% by adding stigma exudates from longstyle female flowers to the planting medium (Awamura et al, 1995). In a study by Ilgın et al (2007), pollen viability was higher than that of pollen germination.…”

This research was carried out in fig fields in the village of Kafar-Jales, in the north of Syria. The analyses were conducted in the laboratories of the Faculty of Agriculture at Idlib University during the 2022 farming season, to evaluate the viability and germination of three local varieties of Caprifig (Bunduqi, Azraq, Panjani). The morphological characteristics, the date of the exodus of insects (Blastophaga psenes) from male fruits, the quantity of pollen, and the percentage of germination and viability were studied on four nutritive media at a temperature of 27°C. The measurements were taken after 24 h, 48 h, and 72 h. These three pollinators were used to pollinate three varieties of edible figs (white Satehi, Safrawi, and Habashi) to study the effect of pollen source on the productive characteristics of edible fig fruits. The result showed significant superiority of the Bunduqi cultivar over the rest of the cultivars in traits of the fruit’s early ripening, pollen quantity, and date of departure of insects. The Azraq cultivar is found to be superior to Bunduqi and Panjani cultivars in the germination rate of pollen at all stages of the experiment and in all used media. The addition of stigma flower extract in culture media increased germination percentage by 35% for all studied Caprifig cultivars. The addition of 10% sucrose in the cultivation environment increased the percentage of pollen germination by 20%. The cultivars that were inoculated with the Panjani pollinator outperformed the characteristics of the length, diameter, and weight, demonstrating that the fruit’s quality characteristics are affected by the genotype of the pollinator used. The results of this research can be beneficial for both fig growers and plant breeders, as they help to select the best pollinators and contribute to the development and improvement of the quality of the cultivated fig fruits.
