“…However, during this same time period (7–2 DBA), there was only a significant reduction in pollen viability in the 7 DBA treatment of A55. Thus, the yield reductions observed during pollen and embryo sac development and anthesis (7–0 DBA) are not explained by the pollen viability and morphological factors investigated in this study and might instead be due to increased inflorescence abscission, to repartitioning between vegetative and inflorescence structures, to pollen/stigma interactions and/or to heat‐induced damage to female reproductive organs (Ormrod et al . 1967; Gross & Kigel 1994).…”

High ambient temperature (32/27 ∞ ∞ ∞ ∞ C, day/night, 12 h photoperiod) applied prior to anthesis to Phaseolus vulgaris plants results in abnormal pollen and anther development during microsporogenesis. Scanning and transmission electron microscopy were used to examine anther and pollen morphology and pollen wall architecture after heat stress was applied to two genotypes that differ with respect to yield potential under high-temperature field conditions: one, a heat-sensitive, Mesoamerican genotype, A55, the second, a heat-tolerant, Andean genotype, G122. Hightemperature treatment of both genotypes was applied 1-13 d before anthesis. Under heat stress, the heat-tolerant genotype showed anther and pollen characteristics that were generally similar to the low temperature controls. In contrast, after 9 d of heat treatment before anthesis, the anthers of the heat-sensitive genotype were indehiscent and contained abnormal pollen. Pollen wall architecture was also affected in the 12 and 13 d treatments. In addition to the morphological changes, the heat-sensitive genotype also experienced reduced pollen viability and reduced yield in high-temperature experiments conducted in both the greenhouse and field.

“…Ovules of tomato exposed to 40 • C for 3 h on two consecutive days four days prior to flower opening contained a degenerated egg and synergids (Iwahori, 1965). Increasing day temperatures from a constant 24 to 35 • C resulted in an increase in degenerated contents of the female gametophyte in bean (Ormrod et al, 1967) although this may have been due to an absence of viable pollen that prevented successful fertilization.…”

Pea (Pisum sativum L.) is a major legume crop grown in a semi-arid climate in Western Canada, where heat stress affects pollination, seed set and yield. Seed set and pod growth characteristics, along with in vitro percentage pollen germination, pollen tube growth and pollen surface composition, were measured in two pea cultivars (CDC Golden and CDC Sage) subjected to five maximum temperature regimes ranging from 24 to 36 °C. Heat stress reduced percentage pollen germination, pollen tube length, pod length, seed number per pod, and the seed-ovule ratio. Percentage pollen germination of CDC Sage was greater than CDC Golden at 36 °C. No visible morphological differences in pollen grains or the pollen surface were observed between the heat and control-treated pea. However, pollen wall (intine) thickness increased due to heat stress. Mid-infrared attenuated total reflectance (MIR-ATR) spectra revealed that the chemical composition (lipid, proteins and carbohydrates) of each cultivar's pollen grains responded differently to heat stress. The lipid region of the pollen coat and exine of CDC Sage was more stable compared with CDC Golden at 36 °C. Secondary derivatives of ATR spectra indicated the presence of two lipid types, with different amounts present in pollen grains from each cultivar.
