Vitality and healthiness of Lupinus angustifolius L. treated with plant extracts

In experiment, the activity of water extracts on the vitality and healthiness of sweet and bitter variety of Lupinus angustifolius L. was examined. The materials under investigation were: macerations, infusions and decoctions made from different morphological parts of 40 plant species. The experiment was performed using a filter paper test [1] with the purpose of the estimation of the following parameters: the germination viability, the germination capacity and the seeds infestation. The significance of correlation coefficients at P = 95% were designed with a mark "*" and at P = 99% with two marks "**". The response of the examined lupine crops to the plant extracts used was different in general. The plant extracts most strongly stimula-ting a lupine seeds capacity were as follows: bitter lupine: decoctions from S. hortensis, S. nigra, A. sativum, R. canina: infusions from C. oxyacantha, Z. mays, T. officinale and macerations from R. nigrum, C. oxyacantha, R. canina. sweet lupine: macerations from Q. robur, L. officinale, C. sativum, L. vera; infusions from L. officinale, Q. robur, C. sativum and decoctions from S. hortensis, M chamomilla, C. sativum, E. arvense. and respectively the lupine contamination was strongly reduced as follows: bitter lupine: macerations from C. oxyacantha, M chamomilla, bark of A. hippocastanum, R. canina, F. alnus; infusions from C. oxyacantha, R. canina, M chamomilla, I. helenium; decoctions from bark of A. hippocastanum, S. hortensis, H. officinalis, B. verrucosa; sweet lupine: macerations from C. sativum, L. officinale; infusions from L. usitatissimum, C. sativum, L. officinale, P. sylvestris, decoctions from I. helenium, M officinalis, B. verrucosa, C. sativum, M vulgare. It was observed as well, that the more the examined decoctions reduced a cereal seed contamination, the higher vitality occurred
