Polymorphism of glucose-6-phosphate dehydrogenase enzyme was studied in the Scots pine populations growing in the sites of Bryansk region which were radioactively contaminated as a result of the Chernobyl accident. It was revealed that the frequency of mutations in isozyme loci increased along with
During our investigation on the effect of some fatty acids on the germination of Pinus pinea seeds (Vincenzini et al., 1973), we noted a marked decrease of G6PDH activity when octanoate or oleate were added to the culture medium. In an attempt to provide biochemical information on the effect of free
This work inserts in the research field regarding the effects of altered gravity conditions on biological plant processes. Pinus pinea seeds germination was studied in simulated microgravity (2x10-3g) and hypergravity (20g) conditions. The effects of simulated gravity were evaluated
Segregation ratios of allozymes in haploid female gametophytes obtained from viable seed were studied in a natural population of jack pine, Pinus banksiana. Stability of these ratios was assessed for three levels of the sexually reproductive crown as well as for four years of natural fertilization.
