Further studies on sour cherry flower biology


, : Further studies on sour cherry flower biology. Roczniki Nauk Rolniczych, A Produkcja Roslinna 106(1): 7-22

Three-year studies were carried out with 2 cultivars. In the Kerezer, the period of effective pollination (PEP) of individual flowers was 2-3 days but the PEP of the trees was 6-11 days. Physiological maturity of the flowers was generally one of the main factors determining the extent and intensity of pollination. Flower pollination was not irreversible; external factors, especially wind, could remove the pollen from the stigma.

Spinel lherzolite and pyroxenite xenoliths from the Rio Puerco Volcanic Field, New Mexico, were analyzed for oxygen isotope ratios by laser fluorination. In lherzolites, olivine 18O values are high (+5.5‰), whereas 18O values for pyroxenes are l...

The effect of the magnetic field depended on its intensity.

Dephosphorylation of phospho GSK3 isoforms, from COS-7 cells, was determined in vitro and in cultured cells in the absence or the presence of okadaic acid and lithium. Our results indicate a preferential dephosphorylation of phospho GSK3α by PP2A...

We compared the effects of MeHg and Hg++ on plasma (...
