Identifying indicators of apple bud dormancy status by exposure to artificial forcing conditions.

Dormancy in temperate fruit trees is a mechanism of temporary growth suspension, which is vital for tree survival during winter. Studies on this phenomenon frequently employ scientific methods that aim to detect the timing of dormancy release. Dormancy release occurs when trees have been exposed to sufficient chill, allowing them to resume growth under conducive conditions.

Insight into the aroma quality of 'Callista' cultivar of hop (Humulus lupulus L.): Impact of harvest timing, year, and location.

Hops (Humulus lupulus L.) are essential ingredients in brewing, contributing to beer's flavor, aroma, and stability. This study pioneers an in-depth analysis of the 'Callista' cultivar, aiming to unravel how harvest timing, annual variations, and cultivation location synergistically influence its molecular profile, sensory perception, and biochemistry.

Physical localization of single-copy sequences on pachytene chromosomes in maize (Zea mays L.) by chromosome in situ suppression hybridization.

A new approach for locating single-copy DNA sequences on pachytene chromosomes of maize (Zea mays L.) was developed. A cosmid clone with homologous sequences to a molecular marker (umc105a) linked to a quantitative trait locus (QTL) for resistance against sugarcane borer (SCB) was physically mapped by fluorescence in situ hybridization (FISH) to the short arm of chromosome 9.

[HLA compatibility and susceptibility to habitual abortion. Results of histocompatibility testing of couples with frequent miscarriages].

We have performed class I HLA antigen testing in 42 women with recurrent habitual abortions and in their husbands. The main criterion for inclusion in this group was a frequency of more than two abortions without the known reasons for abortion and without a living child. 29 couples with a least two healthy children and no abortion in the clinical history served as a control group.
