Lactic acid has been known as one of compounds to cause cellular harm in waterlogged tissues through the process of cytoplasmic acidosis. The effects of lactic acid on α-amylase activity and phytic acid (myo-inositol 1,2,3,4,5,6-hexaphosphate) content using an assay for high phosphate in the germination stage of rice were evaluated. It is showed that lactic acid inhibited rice germination at every treated dose. The reduction of α-amylase content attributed to lactic acid at 24 h after germination of rice seeds was observed. The findings highlighted the effects of lactic acid on α-amylase activity and phytic acid content and suggested that this compound may play a potent role as a germination regulator in rice.

Genetic control of a-amylase activity in rye grain was investigated by QTL mapping/based on DS2 x RXL10 intercross consisting of 99 F₅₋₆ families propagated at one location during four vegetation seasons. A wide range of variation in α-amylase activity and transgression effects were found among families and parental lines. This variation was shown to be determined in 40.1 % by 7 significant (LOD score not less than 2.5) and 2 putative QTLs (2 < LOD < 2.5) distributed on all rye chromosomes except 4R. Two significant QTLs located on 3RL and 5RL chromosome arms were expressed each year. The third significant QTL was detected in three years (1RL). The other four significant QTLs (2RL, 5RS, 6RL, 7RL) were found in one year of study. The number and composition of QTLs were specific for a given year varying from three to six. QTLs were not correlated with isoenzyme polymorphisms at the structural α-Amyl loci. A QTL associated with a region containing the α-Amy3 locus was detected on chromosome 5RL. Both high- and low-activity QTL alleles were found in each parental line, which explains the appearance of transgressive recombinants in the segregating population.

Amaranthus caudatus L. seed germination was studied under different levels of water deficit induced by PEG 6000 in laboratory conditions. PEG at osmotic potentials -0.2 to -0.3 MPa at 24°C in darkness delayed germination and reduced final germination percentage. PEG solutions at osmotic potential lower than -0.3 MPa almost totally blocked seed germination. Ethephon was much more effective than GA3 in reversing PEG-caused inhibition of A. caudatus seed germination. PEG decreased α-amylase activity after 14 h incubation. It decreased β-amylase activity after 14 and 20 h, and caused an increase in total dehydrogenase activity only after 20 h of incubation. Unlike GA3, ethephon increased α-amylase activity in seeds after 12 and 14 h of incubation under water deficit. After 20 h of incubation there was no difference in α-amylase activity in any of the treatments. Neither ethephon nor GA3 affected the activity of β-amylase and dehydrogenase.

Location of the loci that control preharvest sprouting and alpha-amylase activity in rye was studied based on intercross S120×S76, consisting of 110 genotypes of F2 and F3 progenies. The genetic map currently consists of 141 loci distributed in 11 linkage groups, covering a distance of 506.4 cM, and was enriched during this study with 24 sequence-specific markers (7 SCARs, 7 SSRs, and 10 STSs). The extended map was applied for composite interval mapping of the loci controlling preharvest sprouting and a-amylase activity, revealing 3 significant QTLs for preharvest sprouting, located on chromosomes 3R, 5R and 6R (in 1999), and one QTL for a-amylase activity found on chromosome 2R (in 2000).
