The β-endoglucanase is one of the enzymes taking part in the degradation of the cell wall structural polysaccharides. The use of two Triticale varieties differing in their resistance to the preharvest sprouting allowed the comparison of that enzyme activity and changes in the internal structure of the cell wall observed in the light and electron microscope. The most interesting observations seem to be the channels and even the holes in the walls of aleurone cells found mostly in the samples showing the elevated activities of β-endoglucanase. As those samples concern the grains of a lower resistance to pre-harvest sprouting, it might be suggested that the loosening of the wall structure may be one of the probable mechanisms in facilitating the enzyme, metabolite and water translocations through the grain tissues. Those changes can accelerate the water imput into the grain, the metabolic process and thus the increased susceptibility to sprouting.

During the development and ripening of triticale caryopses cv. Grado, a gradual increase in the precocious germination ability of the grain was observed. After 48 hrs of incubation (at 22 °C under optimal moisture conditions for germination in darkness) of the freshly-collected caryopses of different ripeness, the percentage of polysomes in the ribosomal fraction isolated from embryonic tissue in buffer A + PTE (to yield released FP + MBP) was about 15 % in the sample of grains gathered at the milk-ripeness stage, over 27 % at the wax-ripeness stage and over 63 % at the full-ripeness stage. Percentages of polysomes solubilized in the pellets in buffer U (TBP, putative cytoskeleton-bound polysomes), were always higher and amounted to about 36 % at the milk-ripeness stage, 58 % at the wax-stage and 68 % at the full-ripeness stage. The incorporation of 3H-uridine into polysomal RNA (mRNA+rRNA) of triticale embryos increased during the development and maturation of the caryopses subjected to germination from about 19 and 33 Bq/mg RNA at the milk-ripeness in the FP+MBP and the TBP to 220 and 312 Bq·mg⁻¹ RNA at the full-ripeness stage, respectively. The effect of the pericarp and other tissues surrounding the embryo was also investigated. Removal of the outer pericarp strongly stimulated germination of unripe caryopses in the middle period of development e.g. 32 and 39 DAF. The strongest stimulatory effect on transcription was found in the embryo during germination, in all samples of caryopses of various degrees of ripeness, by isolating it completely from the pericarp, testa and endosperm. The high percentage of polysomes in the TBP and the high incorporation 3H-uridine into RNA in that fraction during precocious germination suggests an important role for this sub-population of polysome (and the proteins synthesised by them) in initiation of precocious germination processes.

Investigations were conducted on the level of the overall proteolytic activity in flour fractions as well as fine and bruise bran, obtained from four varieties of wheat (‘Zyta’, ‘Pegassus’, ‘Sukces’, ‘Tonacja’), subjected to pre-harvest sprouting. Moreover, an analysis was conducted on the effect of pre-harvest sprouting on the functional properties of flour, determining the physical properties of gluten and dough. The analyses included a determination of crude protein, non-protein nitrogen, wet gluten, proteolytic activity and the rheologic properties of dough. The studies ended with a trial baking, with vitamin C and vital gluten added as improvers to the flour from pre-harvest sprouted grain. In all the milling fractions the overall proteolytic activity increased as result of sprouting, the highest increase being recorded for variety ‘Tonacja’. Simultaneously, in all the fractions tested an increased level of non-protein nitrogen was observed. Flour obtained from pre-harvest sprouted grain was characterised by an increased water holding capacity and the dough by poorer rheologic properties. Bread obtained from flour from pre-harvest sprouted grain was of insufficient quality. The use of improvers (vital gluten and vitamin C) as a rule resulted in favourable palatability and physico-chemical changes in bread
