“…This indicates that the conservation of pollen in low temperatures (-13 °C), could serve as a way to lengthen the life of the pollen, improving its vigor in subsequent pollination and allowing the production of pollen in areas other than its application. The same results are reported by Pham et al (2015), in Dimocarpus and by Wang et al (2015) in Litchi, with pollen conserved at -86 °C and by Sukhvibul et al (2000) in four cultivars of mango.…”

El éxito de la polinización asistida en palma de aceite es fundamental para la producción de aceite, ya que determina la cantidad de frutos bien formados; en este proceso, la calidad del polen, expresada como viabilidad y germinabilidad, es de gran importancia. El presente trabajo se realizó en los Laboratorios de la empresa Salamanca Oleaginosas S.A., con el objeto de determinar la viabilidad, germinación y velocidad de crecimiento del tubo polínico de granos de polen de los genotipos Guineensis, Amazon, Coari x Lame y Unipalma, almacenados durante 0, 5, 15 y 30 díasa temperatura ambiente y a -13 °C. Se empleó un diseño DIA con un arreglo trifactorial (Genotipos, tiempo y temperatura de almacenamiento) con cuatro repeticiones. El polen del genotipo Guineensis presentó los mayores valores de viabilidad y germinación, asegurando una buen eficiencia en la polinización, mientras que los demás cultivares presentaron valores por debajo de los recomendados; sin embargo, el crecimiento del tubo polínico del polen germinado en estos genotipos, fue similar al del genotipo Guineensis.

“…At 12ºC pollen germination was low (30%, 5%, 0% respectively), whereas it was higher at 20ºC (70%, 39%, 45% respectively) and at 30ºC (79%, 47%, 54% respectively). Similar results were observed by Sukhvibul et al (2000) for `Kensington´. Further work on the temperatures, not only during pollen germination, but also during pollen development may shed light on these differences, as it occurs in other species as cherimoya (Lora et al, 2012), in which temperature in the final stages of pollen development has a reflection on the subsequent pollen performance.…”

The importance of mango growing contrasts with the paucity of information on its reproductive biology. In this work, the reproductive biology of mango was studied in the subtropical conditions of the Southern Spanish Mediterranean coast, using the cultivars `Osteen´, `Kensington´, `Kent´ and `Keitt´. In order to establish the appropriate developmental coordinates during the reproductive phase, phenology was studied from the start of the blooming season to fruit harvest. Also to detect the reasons behind the low fruit set in mango, pollen tube pathway and fertilization were analysed, using microscopy techniques. A good proportion of the flowers were male and dropped soon after anthesis. Pollen grains readily germinated, pollen tubes reached the base of the style within one day, penetrated the ovule through the nucellus and reached the embryo sac three days after pollination. Endosperm nuclei soon developed, but the embryo remained in a quiescent stage. A good proportion of the ovules degenerated at different stages of development. Temperature had an effect on pollen performance, and low temperatures hampered pollen germination. Finally, a compatibility assay was performed, showing no differences between self and cross pollen tube growth in the style. However a paternity analysis, with microsatellite markers, showed significant differences in outcrossing rate depending on the availability of pollinizer trees. INTRODUCTIONIn mango, even after adequate pollination, a very small proportion of the flowers are able to set fruits, due to a massive drop of flowers and developing fruitlets (Davenport and Nuñez-Elisea, 1997). This is especially important in areas such as Southern Spain, where climatic conditions are very different from those in the area of origin of the species, often resulting in erratic bearing.The knowledge about the reproductive biology of species of agronomic interest (Herrero, 1992) and its relation with environmental conditions (Hedhly et al., 2009) is relevant in order to optimize production. But in mango, in spite of the importance of the crop, surprisingly very little is known on its reproductive biology. In this work, in order to study the ultimate causes behind this massive flower and fruitlet drop under a Mediterranean climate, we studied the process that goes from flower to fruit in mango, characterizing its phenology in the field and reproductive process under the microscope.

“…According to Sukhvibul et al (2000), the effect of the temperature on the germination of pollen grains was inconsistent and varied between species and cultivars. In peach trees, Weinbaum et al (1984) observed a germination peak of 20°C, but the same remained relatively high at 7 or 30°C.…”

Pollen germination and pollen tube growth was quantified among various native Iranian wild almonds (P. dulcis (Mill.) D. A. Webb, P. eleaegnifolia Mill., P. orientalis Mill., P. lycioides Spach, P. reuteri Bioss. et Bushe, P. arabica Olivier, P. glauca Browick and P. scoparia Spach in order to identify differences in the tolerance of pollen to temperature variations. Pollen germination and pollen tube growth were observed after incubation in darkness in a germination medium for 24 h at 10-50°C at 5°C intervals. Maximum pollen germination of the wild almond species and specify that 60% was obtained for P. orientalis pollen and 98% for P. scoparia. Pollen tube length ranged from 860 lm was obtained in P. lycioides and 1490 lm in P. scoparia. A modified bilinear model best described the response to temperature of pollen germination and pollen tube length. Almond species variation was found for cardinal temperatures (T min , T opt and T max ) of pollen germination percentage and pollen tube growth. Mean cardinal temperatures averaged over eight almond species were 14.7, 24.2, and 43.7°C for maximum percentage pollen germination and 14.48, 25.3, and 44.4°C for maximum pollen tube length. The principal component analysis (PCA) identified maximum percentage pollen germination and pollen tube length of the species, and T max for the two processes as the most important pollen parameters in describing a species tolerance to high temperature. PCA also classified Prunus L. spp. into four groups according to the tolerance of pollen to temperature variations. The T min and T opt for pollen germination and tube growth, rate of pollen tube growth were less predictive in discriminating species for high temperature tolerance.
