Flowering and Fruit Set in Japanese Quince (Chaenomeles japonica)
The amount of flowers with defective pistils, drop of flowers after pollination, initial fruit set, drop of fruitlets and final fruit set were investigated for Japanese quince (Chaenomeles japonica).
Pollen tube growth and fruit set in quince (Cydonia oblonga Mill.)
The majority of quince cultivars were self-incompatible, and when establishing new orchards with these cultivars, care should be taken about the choice of pollenisers in order to achieve high yields.
Pistillate flower development and pollen tube growth mode during the delayed fertilization stage in Corylus heterophylla Fisch
The female inflorescence development and pollen tube growth mode during the delayed fertilization stage in hazel were investigated by improved paraffin sectioning and aniline blue staining of pollen tubes and showed ovaries and ovules of hazelwere invisible at the time of blooming.
Effective pollination period in "Oblačinska" sour cherry clones
Only clone having long EPP should be used as parents for creating new sour cherry cultivars, that differs in pollen germination, fruit set and yields.
Influences of cross pollination on pollen tube growth and fruit set in Zuili plums (Prunus salicina).
The main causes of poor fruit set of Zuili plums are a lack of effective cross-pollination and the production of high percentages of double pistils in which normally developed ovules are scarcely formed.
Pollen viability, germination, and seed setting of Nelumbo nucifera
The results showed that the low seed-setting rate also came from seed abortion, and a high value of self-incompatibility was observed in RC and NW cultivars, but not in the other cultivars studied.
Significant effect of accidental pollinations on the progeny of low setting Prunus interspecific crosses
The use of molecular markers is discussed in terms of a convenient method for an early identification of putative hybrids in breeding programs with low setting crosses, where the proportion of non-hybrids is magnified.


Pollen-stigma interaction which might be critical to the gametophytic incompatibility of Japanese pear.
It was suggested that the stigma might play some significant role in the function of incompatibility of Japanese pear.
Selecting for improved pollination at low temperatures in apple
SummaryBy studying pollen germination in vitro and the growth of pollen tubes in styles of detached flowers, an assessment was made of differences between apple cultivars in pollen tube growth and
Pollen Germination and Pollen-Tube Characteristics in a Range of Apple Cultivars
A study was initiated to define more fully the characteristics of compatible and incompatible pollen-tube growth in 40 apple cultivars, and found compatible tubes grew rapidly down the style and were characterized by small widely spaced, intermittent callose plugs and the absence of terminal plugs.
Gametophytic Self-Incompatibility Systems.
is one of the mechanisms that have evolved to encourage outbreeding in flowering plants and is defined as “the inability of a fertile hermaphrodite seed plant to produce zygotes after
In vitro germination of apple pollens
Germination and storage of pollen
Both apple and pear pollen remained viable longest at both low humidity and temperature, and in deep-freeze longevity was more than 2 years at -180°, while the pollen sensitivity to boron in vitro remained unchanged.
S-RNases in apple are expressed in the pistil along the pollen tube growth path
S-proteins were shown to be localised in the intercellular space of the transmitting tissue, both in the stigma and style, which agrees with the proposed mechanism of action for S-RNases in gametophytic self-incompatibility.
Identification of stylar RNases associated with gametophytic self-incompatibility in almond (Prunus dulcis).
N-terminal amino acid sequence analysis of the four S-proteins revealed that they were highly homologous to each other and similar to the S-RNases of Malus, Pyrus, Scrophulariaceae, and Solanaceae.
Staining and observing pollen tubes in the style by means of fluorescence.
Pollen tubes in the styles of the tomato and of other flowering plants can be observed by using the following technic. Styles are fixed in formalin-acetic-80% alcohol (1:1:8) and cleared and softened
