“…In contrast, second pollinations delayed 1 or 2 days were more effective than first pollinations in apple (Visser and Verhaegh, 1980) and pear (Visser and Marcucci, 1983). In these studies, the first pollination apparently "paves the way" for the second.…”

The relationship between pollination order and the transmission of male genes to seed was investigated by performing a large number of genetically marked, double and mixed artificial pollinations in the common morning glory, Ipomoea purpurea. Second pollinations were substantially less effective than first pollinations, even when applied immediately afterwards. When delayed 30 and 60 minutes, effectiveness was reduced further to about 14 and 7 per cent of fertilisations, respectively. After 120 minutes, effectiveness decreased to less than 2 per cent. Among a set of mixed pollinations, pollen from some individuals suffered a strong disadvantage in competitive ability. This disadvantage is partially genetic.The primacy of first pollinations, and the presence of strong pollen competition, have implications for studies of pollination biology and genetic transmission in natural populations of Ipomoea purpurea and other plant species. Specifically, sequential pollination ineffectiveness, and strong competition within pollen loads, should reduce the numbers of paternal parents and thus increase the numbers of full sibs among outcross seed within capsules. This represents a substantial violation of one of the critical assumptions in the mixed mating model and could influence the genetic structure of Ipomoea populations. In addition, these data indicate that gametophytic selection may be an important component of natural selection in Ipomoea. The mechanisms underlying the sequential and competitive effects probably include pollen-stigma interactions, differential pollen production, viability differences, or pollen tube growth rate differences, and possibly embryo abortion.These experiments also establish that outcrossing rates vary among individuals in natural populations, due to genetic variation in the distance between anthers and the stigmatic surface.

“…In the case of the pioneer pollen technique (VISSER & VERHAEGH, 1980;VISSER, 1981) the first applied pollen supposedly stimulates the growth of the pollen applied afterwards, this effect, which has been studied in apple and pear (VISSER, 1981;VISSER et al, 1983), could well be equally causal to a 'mentor pollen-effect', but has yet to be investigated for a wider range of species.…”

“…In apple and pear, the second pollination, 1 d after the first, is much more efficient (13,14), particularly under the appropriate conditions of temperature (12). This conclusion was derived from the ratio ofseedlings having different genetic markers, from which the pollen source could be traced back.…”

The effect of ethylene on the growth rate of pollen tubes in styles of Petunia hybrida was exin. Apart from its strong inhibition of pollination-induced ethylene synthesis, anothoxyvinylgycine, placed on the stigma, did not impede tube growth. The inhibitors of the action of ethylene, silver thiosulfate and 2,5-norbornadiene, were similarly ineffective. Application of the ethylene precursor, 1-amino-cyclopropane-1-carboxylic acid, onto the stigma at different intervals prior to pollination evoked synthesis of ethylene, but was without effect on tube growth. However, prepollination (by 24 hours) with Nicotiaxa tabacum pollen, significantly enhanced tube growth of Petunia pollen. This enhment was not counteracted by the pretreatment of stigmas with amithoxyvinylglycine. It is concluded that the ethylene associated with pollination is without effect on pollen tube growth in the style, but that other pollination-induced factors may lead to an acceleration of growth.
