“…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.

“…Coari x Lame reached 628.18 µm, Amazon 613,9 µm Unipalma 593.9, and Guineensis 572.6 µm ( Figure 4B). In this sense, Pham et al (2015) affirm that germination and growth of the pollen tube require the interaction of different components, and that it is necessary to evaluate and calibrate according to the specie and genotype.…”

“…Alternatively, it may be plastic to maximize reproductive output under different environmental conditions. One of the most studied and influential factors limiting pollen growth and development is temperature (Hedhly, Hormaza, & Herrera, 2004;Rang, Jagadish, Zhou, Craufurd, & Heuer, 2011), but the studies are mainly focused on the conditions during germination and pollen tube growth (Alcaraz, Montserrat, & Hormaza, 2011;Pham, Herrero, & Hormaza, 2015). Although several studies have provided examples of how environmental conditions during pollen maturation influence their chemical composition (Lau & Stephenson, 1994;Stanley & Linskens, 1974;Zimmermann & Kohler, 2014), the role of pollen chemical composition in adaptation is rarely investigated.…”

The two factors defining male reproductive success in plants are pollen quantity and quality, but our knowledge about the importance of pollen quality is limited due to methodological constraints. Pollen quality in terms of chemical composition may be either genetically fixed for high performance independent of environmental conditions, or it may be plastic to maximize reproductive output under different environmental conditions. In this study, we validated a new approach for studying the role of chemical composition of pollen in adaptation to local climate. The approach is based on high‐throughput Fourier infrared (FTIR) characterization and biochemical interpretation of pollen chemical composition in response to environmental conditions. The study covered three grass species, Poa alpina, Anthoxanthum odoratum, and Festuca ovina. For each species, plants were grown from seeds of three populations with wide geographic and climate variation. Each individual plant was divided into four genetically identical clones which were grown in different controlled environments (high and low levels of temperature and nutrients). In total, 389 samples were measured using a high‐throughput FTIR spectrometer. The biochemical fingerprints of pollen were species and population specific, and plastic in response to different environmental conditions. The response was most pronounced for temperature, influencing the levels of proteins, lipids, and carbohydrates in pollen of all species. Furthermore, there is considerable variation in plasticity of the chemical composition of pollen among species and populations. The use of high‐throughput FTIR spectroscopy provides fast, cheap, and simple assessment of the chemical composition of pollen. In combination with controlled‐condition growth experiments and multivariate analyses, FTIR spectroscopy opens up for studies of the adaptive role of pollen that until now has been difficult with available methodology. The approach can easily be extended to other species and environmental conditions and has the potential to significantly increase our understanding of plant male function.

, flowers were collected from eight Rosaceae species. Flowers were kept in a freezer at-20 ºC for three freezing times (Treatment 1, two months; Treatment 2, four months; Treatment 3, six months). After extracting pollen, in vitro germination was induced in a culture medium and incubated at six different temperatures for 72h. The percentage of pollen germination, average pollen tube length and maximum pollen tube length were measured. Pollen germination was maximum for all species between 15 ºC and 30 ºC. Cydonia oblonga, Malus sylvestris, Prunus avium, Prunus domestica, Prunus dulcis, Prunus persica and Pyrus communis obtained 30-52%pollen germination between 15 ºC and 20 ºC. Prunus cerasifera had 40% pollen germination at 30 ºC. All species studied reached the maximum pollen tube length between 10 ºC and 25 ºC. Germination did not change significantly for any of the species with freezing time, but we found significant differences in the three parameters measured between treatments. The highest germination percentages were obtained in Treatment 2 (four months frozen at-20 ºC), while the maximum pollen tube length was reached in Treatment 1 (two months frozen at-20 ºC). According to our results, freezing time affected the germination-temperature patterns. This could indicate that studies on the effect of temperature on pollen germination should always be carried out with fresh pollen to obtain more conclusive data.
