ABSTRACT
The objective of the study was to determine the effect of three different doses of laser radiation on the morphological features determining the yield of spring wheat. The field experiment was set up according to the randomized blocks method in Swojec near Wroclaw, in 1991. The object of the analyses were control seeds and wheat seeds treated with three doses of laser radiation. Biometric measurements of nine features were performed on plants random sampled from every plot. It was found that among the morphological features of the spring wheat cultivars under study the effect of laser radiation proved to be significant with relation to total and productive tillering, length of ear, weight of grains per ear, and weight of 1 000 grains. In the case of the weight of 1 000 grains, significant interaction occurred between the cultivars and between the three doses of laser radiation. In the case of the very important feature of the yield structure – the weight of grains per ear, dose 11 (97.2•10–3 J/cm2) proved to be a factor significantly increasing the value of that parameter as compared to the control and to the other laser radiation doses.
