“…However, incompatibility occurred in the upper style in many L-morph pistils of our study and in some S-morphs pistils of the population studied by Castro and Araújo (2004). Temperature and humidity are two factors that can influence pollen grain germination and pollen tube growth rates for some Primula species (Mckee and Richards 1998;Shivanna et al 1981, respectively). Environmental conditions also possibly affect pollen germination and pollen tube growth rate in P. nuda and the timing of incompatibility reactions.…”

Heterostyly is a genetically controlled floral polymorphism usually associated with an incompatibility system. This set of features is known to occur in several angiosperm families, but some aspects of its biology has not been well studied. The present study investigates cellular aspects of the pollen-pistil interaction after compatible and incompatible pollinations of Psychotria nuda, to increase our knowledge of heteromorphic self-incompatibility (HetSI). The use of bright field, fluorescence and transmission electron microscopy methods allowed us to demonstrate that pollen tubes behave differently after incompatible and compatible pollinations. Pollen tubes were particularly distinct after incompatible pollinations of L- and S-morph flowers. Relative to compatible pollen tubes, incompatible L-morph tubes had a drastic reduction in cellular contents, but no cell rupture. Incompatible S-morph tubes exhibited dense cytoplasm in apical regions, as well as in other regions, accompanied by a rupture of the apex. These results support the hypothesis that L- and S-morph flowers have different incompatibility mechanisms during HetSI.

“…Ottaviano and Mulcahy (1989) argued that due to pollen sensitivity to environmental conditions, pollen should show higher viability in the environment where the pollen Page 13 of 24 A c c e p t e d M a n u s c r i p t 13 producing plant grows. This might lead to intra-specific variation in optimal temperature for reproductive development (Mckee and Richards, 1998). Intra-specific variability has indeed been extensively reported in cultivated plant species for many reproductive characteristics.…”

Research on plant responses to temperature stress is receiving increased interest due to the growing awareness about global warming. High and low temperature stresses help establish the narrow geographic distribution of some cultivated plants, the limited geographic extension of some other economically nutritionally important species, and also induce irregular bearing for some species. However, the understanding of plant responses to temperature stress lags behind other biotic and abiotic stresses probably due to the complex response at the molecular, cellular, and organismal level. Temperature stress affects, indeed, many developmental processes during the plant's life cycle. However, the reproductive stage, the outcome of which represents the economic value for many cultivated plants, is especially vulnerable. Here the effect of low and high temperature stresses during the flowering phase is reviewed in flowering plants in an attempt to unravel sensitive stages that are behind irregular cropping. The review presents detailed findings from 33 previously published reports spanning 19 different flowering plant species. Both the male and female organs of the flower are especially sensitive to temperature fluctuations both during their development before pollination and during the post-pollination stage. The effect of temperature stress is, however, obscured by the complex male-female interaction superimposed on the individual behavior of each organ. Interestingly, a review of the literature on this topic shows that genetic variation does exist in reproductive behavior under temperature fluctuations. This genetic diversity must be preserved and characterized in further detail to understand how plants naturally cope with changing environmental conditions, which will, undoubtedly, help us to design better strategies to face current and future challenging temperature fluctuations.

“…Both colors should facilitate anther development in the flowering seasons by flowering and opening/closing at the proper time that is critical to pollen growth (McKee and Richards, 1998a). Mølgaard (1989) has observed that the white flowers of Papaver radicatum occur in the North Greenland coast where sunshine is limited, while the yellow flowered plants are more common inland and at higher elevations (Mølgaard, 1989).…”

“…In contrast, in arctic or cold alpine regions, flower color may have evolved to help keep interior temperatures warm and stable against fluctuating ambient temperatures (Seymour and SchultzeMotel, 1998;Ivancic et al, 2008;Li and Huang, 2009), which is critical to the development of pollen, ovules, and fertilization (McKee and Richards, 1998a;Li and Huang, 2009). For example, the white petals of Crocus chrysanthus, an arctic herb species, redirect light spectra into flower interiors, trapping heat energy to warm the gynoecia (McKee and Richards, 1998b).…”
