Twelve species of Avena, including 15 varieties, were used for the observation of the time when flowers begin to bloom every day. The observed plants were grown in pots under natural conditions, and the blooming time was observed every 30 minutes from April 19 to June 1, 1969.Based on the mean time of blooming they were divided into four groups, afternoon-blooming type (4:00-4:30 p.m.), evening-blooming type (7-9 p.m.), night-blooming type (about 10 p.m.) and morning-blooming type (about 4 a.m… Expand
Some aspects of cross-pollination in wheat (Triticum aestivum L.) 1. Pollen concentration in the field as influenced by variety, diurnal pattern, weather conditions and level as compared to the height of the pollen donor
TLDR
Investigations showed that a greater concentration of pollen was found below the ear level of pollinator plants than at or above ear level, and that a male-sterile parent that is shorter than its pollinator would be most likely to produce good seed set in the hybrid wheat seed production field.

Triple fusion of the primary endosperm nucleus as a cause of interspecific cross-incompatibility in Avena
TLDR
The triple fusion of two polar nuclei with a secondary male nucleus is apparently a sexual isolation mechanism, being a barrier to interspecific hybridization in Avena or probably angiosperms. Expand
Causal Relationships between the Polar Nuclei in Double Fertilization and Interspecific Cross-incompatibility in Avena
TLDR
In double fertilization of angiosperms the triple fusion of two polar nuclei with a secondary male nucleus is apparently a biological isolation mechanism and may be the most effective barrier to hybridization on occasion. Expand
Evaluation of resistance to Fusarium graminearum in oats
TLDR
This review demonstrates the current techniques used in the phenotyping of oats resistance to FHB and an outlook to the future prospects of FHB resistance breeding in oats is provided. Expand
Interspecific cross-incompatibility due to disturbed activation of the polar nuclei by the male nucleus
TLDR
It is shortly stated that interspecific crosses of Avena are only compatible when their activation indexes fall within a range from 20 to 80 %, and the triple fusion of the two pdlar nuclei with the male nucleus In angiosperms seems to be a sexual isolation mec. Expand
MEIOTIC CHROMOSOME PAIRING IN TWO INTERSPECIFIC HYBRIDS AND A CRITICISM OF THE EVOLUTIONARY RELATIONSHIP OF DIPLOID AVENA
TLDR
Based on the available cytogenetic evidence the authors arranged all diploid oats in three groups with AsAs (or AA), TATA and CC genomes so that they might have a common ancestor and make progress in different trends of their unique specialization. Expand

TLDR
The pattern of relationship between the crossability, including plumpness, germination and others of hybrid seeds, and the AI% was found to completely agree with that expected from the standard cross-compatibility system in Avena. Expand

TLDR
The present author has found that there are some remarkable differences among the four groups of Triticumm and its allied genera as to the modes of flowering. Expand
SEED SET OF ANEUPLOIDS OATS IN DIFFERENT ENVIRONMENTS
TLDR
Some oat plants with 40∼42 chromosomes (2n) were grown in a greenhouse, controlled at 19.4°C for around eight months from September, 1965 to May, 1966, and were sterile or extremely low fertile in two harvest periods, but moderately fertile in the period from March 31 to May 12. Expand
CHROMOSOMAL DIFFERENTIATION AND SPECIATION IN DIPLOID AVENA. III. MEDITERRANEAN WILD POPULATIONS
TLDR
Data is reported on cross-cbmpatibility, fertility and chromosome behaviour at meiosis in hybrids within the A,, and.^, and between the A, and A, ltaryotype groups. Expand
CHROMOSOMAL DIFFERENTIATION AND SPECIATION IN DIPLOID AVENA
TLDR
Based on lcaryotypes it was found that this species has a ~riodification of the A genome, and was designated as A', but this finding did not coincide with the general pattern of speciation in thc genus, thus further studies were suggested. Expand
