“…Cavalcante et al (2000) analyzed 70 plants of an open-pollinated Citrus population and reported a meiotic index above 90% in 94.1% of the plants. However, all plants with a meiotic index lower than 90% had low pollen viability.…”

The present work analyzed the stainability and in vitro germinability of the gamma-ray-irradiated fresh and cryopreserved pollens of 3 Citrus species: C. limon, C. limetta, and C. sinensis. Fruit set after pollinating 75 flowers of C. grandis with irradiated and nonirradiated (control) fresh and cryopreserved pollen was also assessed. Results showed that in solid and liquid culture media the highest in vitro germination values were detected in fresh (61.45% and 62.53%, respectively) as well as cryopreserved (53.17% and 55.36%, respectively) C. sinensis nonirradiated pollens. However, at a higher irradiation dose of 500 Gy in both culture media, the minimum reduction of germinability of fresh (30.85% and 28.01%) and cryopreserved pollens (33.37% and 31.06%) was found in C. limon. Contrary to in vitro germination, the minimum reduction in stainability of fresh and cryopreserved pollens, as assessed by acetocarmine (9.51% and 11.85%, respectively) and FDA tests (10.78% and 12.73%, respectively), was recorded in C. limetta. Regardless of irradiation dose, the highest fruit setting in C. grandis at 40 days after pollination was detected when it was pollinated with both fresh (38.02%) and cryopreserved (34.92%) C. limetta pollen grains.

“…For pollen in vitro germination, the experimental temperature used (25 ± 2 °C) is the one described as ideal for pollen germination in citrus (Cavalcante et al 2000, Distefano et al 2012. Differences in pollen germination between plants grown in the greenhouse (lower values) and those grown in the field (higher values) were found (Table 3).…”

-The aim of the present study was to evaluate the possible effect of environmental factors on meiosis, meiotic index, pollen viability and in vitro germination of pollen from stock plants of the rootstocks Trifoliate, 'Swingle', 'Troyer', 'Fepagro C13', 'Fepagro C37' and 'Fepagro C41' grown 28%, 56.23% and 74.74%, and, in the greenhouse, 64.25%, 41.41% and 66.71%, respectively. As temperature oscillations were higher in the greenhouse than in the field, we suggest that this negatively affects the reproductive characteristics analyzed.
