Redukcja liczby pąków kwiatowych na roślinach bobiku powodowała przedłużanie strefy generatywnej, zwiększanie wysokości roślin, powierzchni liści i wartości wskaźnika trwałości ulistnienia (LAD) oraz suchej masy łodyg. Efekty te były tym silniejsze im niżej na pędzie pozostawiano zawiązki kwiatów. Uniemożliwienie rozwoju organów generatywnych na dolnych węzłach strefy kwitnienia wywoływało kompensacyjne reakcje w górnych częściach pędu, polegające na zwiększaniu procentu kwiatów zawiązujących strąki, procentu strąków osiągających dojrzałość oraz wielkości nasion.

After-effects of restriction of flower buds development in particular zones of shoot in field bean were studied in pot experiment. The limitation caused the extension of the zone of flower buds setting, the increase of plant height and leaf area as well as of the value of leaf area duration (LAD) and dry matter of stem. The lower the flower buds were left on the shoot, the stronger were the effects. On the other hand when the flower buds were not allowed to develop on lower nodes this was compensated by the larger number of flowers setting pods and of maturing pods in the upper parts of plants and also by the increase of seed weight. The most accentuated effect was observed when flower buds were allowed to develop only on the uppermost part of shoot when the zone of plant devoided of the flower buds was the longest.

Seedlings of hybrid forms of winter triticale and of their parents were hardened against frost and their frost resistance was determined. Three groups of cultivars were separated with respect to their frost resistance: 1) Low resistant: Salvo and Bolero, 2) Intermediate: Almo, Ugo and LAD 490, 3) High resistant: Tewo, Bogo, Tornado, Nemo and Vero. Heterosis in relation to frost resistance was not significant when the hybrid forms were compared with a better parent, but it appeared while comparing the frost resistance of some hybrid forms with mean values of that of parents.

The effect of a short (7 days) and prolonged (14 days) soil drought (D) on leaf optical properties (R reflectance, T transmittance and A absorbance) in PAR and NIR range of irradiation, and on changes in leaf water potential (ψ), leaf injury index (LI), leaf thickness (LT) and chlorophyll (a + b) content (Chl) was studied for maize and triticale genotypes differing in drought tolerance. Under control conditions (C) leaves of maize in comparison to triticale were better hydrated, were thicker and had higher content of chlorophyll (a + b). In non-stressed plants, small differences were observed in measurements of R, T and A. In the range from 500 to 600 nm, the differences between D-resistant and D-sensitive were observed only in transmittance (T) and in range from 700 to 1,100 nm in absorbance (A). In genotypes belonging to the group of D-sensitive T in PAR range and A in NIR range were two times higher than in D-resistant ones. However, in NIR range R for D-sensitive genotypes was lower than for D-resistant ones. The drought stress caused the decrease in ψ, Chl, LT and the increase in leaf injury index (LI). Soil drought applied within 14 days caused larger changes in these physiological characters in comparison to 7 days drought. The observed harmful influence of drought was more visible for maize than triticale. Moreover for genotypes belonging to D-sensitive ones, changes were larger than for D-resistant ones. Similar to changes in ψ, LT and LI drought stress caused changes in leaf optical properties parameters R, A and T. In the PAR range, the highest changes were observed in R, whereas changes in T and A, which were not considerable. Both in maize and triticale, increase in R was higher in plants subjected to 14 days drought than in plants exposed to drought for 7 days. In maize, increase in R was larger for D-sensitive genotype. For both species, changes in T and A of PAR range were small. In NIR range, an increase in R and A, and decrease in T were observed. After 7 days of recovery in plants subjected to shorter period of drought significant differences were still visible in most cases. The same was observed for ψ, LT, LI and Chl parameters. It shows that the period of 7 days rehydration is too short to remove the injuries caused by drought stress. This results indicate that measurements of R, T and A might be useful in practical application for the estimation of the drought tolerance level. Some limitations in the practical application for plant breeding may be caused by relatively high cost of necessary equipment.

The effects of mycotoxin zearalenone (ZEN) on the photochemical activity of photosystem II (PSII) in wheat and soybean leaf discs incubated in ZEN solutions as well as the after-effects of pre-sowing soaking of seeds in solutions containing ZEN on the photochemical activity of PSII and on the seedlings growth under salt stress (NaCl solutions were investigated). The incubation of wheat leaf discs in ZEN solutions strongly inhibited the energy flux per cross section (CS) for absorption (ABS/CS), trapping (TRo/CS) and electron transport (ETo/CS), while the effects of ZEN action on soybean discs were opposite and the values of those parameters significantly increased with the increase in ZEN concentration. Incubation of seeds in a ZEN solution resulted in an increase in photochemical efficiency of PSII in soybean seedlings, but did not induce any response of PSII in those of wheat at medium illuminations. Only at the stronger illumination for both species did ZEN induce an increase in efficiency of excitation energy capture by open PSII reaction centers, photochemical quenching of chlorophyll a fluorescence and quantum yield of PSII electron transport. Pre-sowing soaking of seeds in a ZEN solution decreased the photoinhibitory injuries of PSII in wheat and soybean due to safe scattering of the excess excitation energy through an increase in energy-dependent quenching (qE) and state transition quenching (qT). ZEN when added to NaCl solutions during the period of germination contributed to reduction in the growth inhibition of wheat seedlings. The incubation of wheat leaf discs in ZEN solutions strongly inhibited CS, ABS/CS, TRo/CS and ETo/CS. Possible effects of ZEN on some physiological processes in plants have been discussed especially in the context with photochemical activity of PSII and a salt stress.
