“…In addition, the results of the current study do agree with previous reports from other taxa e.g. Hydrophyllum appendiculatum (Wolfe, 1995), Lesquerella fendleri (Mitchell, 1997) and Mirabilis jalapa (Niesenbaum, 1999;Davis, 2004), and Pachycereus schottii (Holland et al, 2009), which have shown that pollen donor diversity did not affect on seed and fruit set nor on later components of life history. In contrast, the pollen donor diversity in Rhamnus alpinus has been reported to affect on different reproductive components of F 1 progeny e.g.…”

These studies indicated that the levels of offspring performance in plants are mainly controlled by maternal parent, while the impact of paternal parent on the progeny performance has been less investigated (Holland et al, 2009). Therefore, it is important to understand the effects of pollen donor diversity on progeny performance in plants (Leishman et al, 2000;Westoby et al, 2002;Beaulieu et al, 2007).…”

Studies on the parental role on progeny performance have mostly focused on the maternal parent, while less attention was given to the paternal parent. This study investigated the impact of paternal pollen sterility (ranging from 3.1 -to 77.2%) on F 1 seed germination and progeny survivorship in Fragaria (strawberry, Rosaceae) using controlled crosses. In crosses within F. vesca ssp. vesca the paternal pollen sterility was not correlated with F 1 seed germination (N = 14, p > 0.074) and progeny survivorship (N = 14, p > 0. 0.710). Paternal sterility in crosses between F. vesca ssp. vesca and F. vesca ssp. monophylla did not affect on F 1 seed germination (N = 7, p > 0.295) and progeny survivorship (N = 6, p > 0.812). Similarly, no correlation was found between father pollen sterility and F 1 seed germination (N = 6, p > 0.924) and progeny survivorship (N = 6, p > 0.215) in crosses between F. vesca ssp. americana and F. vesca ssp. vesca. Furthermore, crossing different maternal plants by pollen of the same paternal plant in all three cross types produced progeny with variable levels of F 1 seed germination and survivorship. These results indicate the crucial role of maternal plant on progeny performance and support the general idea of the importance of maternal rather than paternal parent on progeny performance.

“…In agreement with this hypothesis is the fact that many studies have found maternal effects on seed size (Roach & Wulff 1987;Mousseau & Fox 1998;Galloway et al 2009;Holland et al 2009), and only rarely have paternal effects been observed (e.g. Marshall & Whittaker 1989;Andersson 1990).…”

Paternal effects inArabidopsisindicate that offspring can influence their own size

et al. 2010

The existence of genetic variation in offspring size in plants and animals is puzzling because offspring size is often strongly associated with fitness and expected to be under stabilizing selection. An explanation for variation in seed size is conflict between parents and between parents and offspring. However, for this hypothesis to be true, it must be shown that the offspring genotype can affect its own size. The existence of paternal effects would support this hypothesis, but these have rarely been shown. Using a diallel cross among four natural accessions of Arabidopsis thaliana we show that maternal, paternal and positional effects jointly influence seed size, number and the frequency of seed abortion. We found that seed abortion (%) depends on the combination of maternal and paternal genotypes, suggesting the existence of mate choice or epistatic incompatibility among accessions of A. thaliana. In addition, since paternal genotype explains approximately 10 per cent of the variation in seed size, we propose that A. thaliana's offspring must influence the amount of resources allocated to themselves. Identification of paternal effects in Arabidopsis should facilitate dissection of the genetic mechanisms involved in paternal effects.

“…The negative impacts of mixed pollination in this study (significant between the two hand-pollination treatments for fruit mass and seed number in S. repandus) are likely to be due to direct pollen interference from the other species when pollen is limiting. Holland et al (2009) found that pollen load accounted for less than 6% of the variation in seed and fruit mass of Pachycereus schottii.…”

Effects of mixed‐species pollen load on fruits, seeds, and seedlings of two sympatric columnar cactus species

Two sympatric species of columnar cacti on Curac¸ao, Netherlands Antilles, share bat pollinators, overlap in flowering phenology, and are floral homologues. Leptonycteris curasoae curasoae and Glossophaga longirostris elongata (Chiroptera: Glossophaginae) visit flowers of Stenocereus (syn. Ritterocereus) griseus and Subpilocereus (syn. Cereus) repandus on the same nights; these visits may promote interference competition between cactus species. I studied the effect of heterospecific (mixed) pollen loads on fruit and seed set, fruit and seed size and mass, germinated seeds at 5 weeks, and seedling survival at 7 months in relation to hand pollination with intraspecific pollen and natural pollination. Hand pollination seemed to limit pollen loads available for pollination. Under these conditions, natural pollination tended to produce the most fruits and seeds, and the largest fruits (but lightest seeds); mixed pollination was the least effective treatment (fruit set was significantly greater for St. griseus in natural than mixed pollination; fruit volume was greater in natural than mixed pollination for S. repandus, and seed number and fruit mass were larger in intraspecific than in mixed pollination). Aspects of natural pollination, possibly repeated visits, compensated for the negative impact of interspecific pollen loads under pollen limitation, with positive impacts on the carrying capacity of cacti for frugivores. Seed mass from natural pollination was negatively correlated with seed number only for St. griseus. Germination success was not correlated with seed mass, but seedling survival at 7 months was for S. repandus. The two species do not seem to compete through pollen interference when pollinator visits are relatively frequent.
