Autogamy of polyploid apple varieties and forms

Russian Agricultural Sciences, 2014
Long-term study of triploid varieties obtained from crossing of diploid varieties and forms with tetraploid ones has resulted in showing their high autogamy. In the case of natural self-pollination of the Rozhdestvenskoe triploid variety, the fruit yield was 12.6%, and that in the case of its cross-pollination with other varieties averaged only 9.55 ...

A new mutation in the timing of autogamy in Paramecium tetraurelia

Mechanisms of Ageing and Development, 2005
We have isolated a new type of Paramecium tetraurelia mutant, named rie-2, that has a long immaturity period until autogamy. We previously isolated such an autogamy mutant, designated rie-1. These two mutants had some additional common features such as dependence of the occurrence of autogamy on the temperature, involvement of a single recessive gene ...

Autogamy is induced in Paramecium bursaria by methyl cellulose

European Journal of Protistology, 2004
When isolated single cells of Paramecium bursaria were treated with 1.25% methyl cellulose, most of the single cells showed nuclear changes which were substantially similar to those seen in conjugation, suggesting that the cells undergo autogamy. Additional cytological observations indicated that the cells underwent normal nuclear processes during ...

Autogamy inHieracium Subgen.Pilosella

Folia Geobotanica, 1999
The presence of autogamy inHieracium subgen.Pilosella is reported for diploidH. lactucella and tetraploidH. pilosella. Self-compatibility is induced under the influence of pollen from another species (mentor effects).

Autogamy in Allogromia laticollaris (Foraminifera)

The Journal of Protozoology, 1970
SYNOPSIS.The life cycles of 2 strains ofAllogromia laticollaris(CSH and TPA) raised on experimentally restricted diets have been studied. Cloned cultures of the strains differed in nutritional requirements for continuous reproduction. The TPA strain was more fecund.
