Diallel crosses among 6 Avena sativa L. and A. sterilis L. lines and introductions were used to evaluate the validity of the assumptions for the genetic model. Number of days to pollination, plant height at pollination and at maturity, as well as grain and stem protein percentages were evaluated. According to Griffing's method 1 the reciprocal mean squares for all the traits under study were si...

Germination of strawberry seeds from self- and cross pollination of 4 commercial cultivars were evaluated under mist and in vitro cultures. The study was conducted in McGill University in Quebec, Canada, during 1994 and 1995. Self-pollination of Chambly and Redcoat cvs., and cross pollination of Oka × Chambly as well as Redcoat × Veestar and their reciprocals were used. At maturity, fruits were...

18 The effect of the pollination time and of the pollen origin was studied in three self-compatible 19 and late-blooming almond genotypes in order to evaluate their effect on fruit set and yield. 20 The full self-compatibility of the three genotypes was clearly assessed as fruit sets after self21 pollination were similar to those obtained after cross-pollination with pollen from two 22 differen...

The effects of two viviparous genes, vp(1) and vp(5), on development of the maize (Zea mays L.) embryo and endosperm were investigated. Differences between viviparous and normal embryos first appeared at 25 to 30 days after pollination. Increases in fresh weights indicated that viviparous began to grow more rapidly than normal embryos at that time. Amino acids and ethanol-soluble carbohydrates ...

Self-incompatibility is one of the most prominent inhibiting factors in almond production which reduces fruit set, making orchard management difficult. Therefore, breeding of almond to produce self-compatible genotypes is indispensably important. In this research work, pollen tube growth rate was studied in 38 genotypes obtained from crossing between Touno (male parent) and Shahrood 12 (female ...

This study explored the morphological characteristics and effects of pollination methods on fruit set and characteristics in 4 red pitaya (Hylocereus spp.) clones. The distinctive morphological recognition and classification among pitaya clones were confirmed by the stem, flower and fruit features. The fruit production season was indicated from the beginning of May to the end of August – the be...

BACKGROUND AND AIMS The pollination drop is a liquid secretion produced by the ovule and exposed outside the micropyle. In many gymnosperms, pollen lands on the surface of the pollination drop, rehydrates and enters the ovule as the drop retracts. The objective of this work was to study the formation of the pollination drop in Juniperus communis, its carbohydrate composition and the response to...
