ALLELOPATIC COMPATIBILITY OF COMMON BEAN AND COMPANION CROPS

Purpose. To investigate the allelopathic compatibility of common bean seeds and companion crops, to establish interaction patterns using water extracts from other plant parts crops. Methods. Laboratory, statistical. Results. Biotest: germinating crops in Petri dishes. Biologically active substances winter spring triticale (the seeds/seeds ratio was 1:10) negatively affected seedlings, which seen all parameters under investigation: hypocotyl length (with root included), longest adventitious root, number, true leaf epicotyl included). At a 1:5, triticale-induced inhibition growth enhanced up 38 %, while, on contrary, had neutral effect this parameter. A stimulating (106 %) epicotyl) noted. For 1:1 (compared control – without crops), with by 21 % 10–9 respectively, is observed. germination extract whole Water 1:2 greatest tap first lengths; 1:4 an length. vegetative mass, roots post-harvest residues bean, weakly inhibited main elongation. seed exerted triticale. top negative seeds, indicating self-incompatibility crop. Conclusions. The laboratory tests showed that biologically both at 1:10 were toxic for ssedlings. Combined 1:5 more positive compared ratios combined demonstrated very similar seeds.
