Plant Introduction| Резюме: | Pollen germination of invasive species Impatiens parviflora DC. is investigated in different mediums separately and together with pollen grains of other plants using method in vitro. The score which characterize direction and intensity of different plants pollen interference – IAS (antagonism–synergism index) – is devised. The inhibition of pollen grains germination of Impatiens parviflora by pollen Rudbeckia hirta L., Rubus serpens Weihe ex Lej. et Court. and stimulation by pollen Lysimachia nummularia L. is observed. The methodology of two-factor experiment is revealed that the presence of antagonist species (biological agent) more severely increased effectiveness of pollen germination Impatiens parviflora than the presence of physiologically active substances (chemical agents). |
