Abstract
Allelopathy is the direct or indirect harmful effec t which one plant produces on another through the production of chemi cal compounds that escape into the environment. In the presence paper allelopathic rel ationships were determined in three cereals - wheat ( Triticum aestivum L.), barley ( Hordeum vulgare L.), oat ( Avena sativa L.) and vegetable crops - spinach ( Spinacia oleracea L.), radish ( Raphanus sativus L.), pepper ( Capsicum annum L.). In addition to the percentage of germination, allelopathic potential was tested measuring root and stem length of tested plant species germinated either alone or in combination with others. The obt ained results showed that seed germination and plant growth of cereals and vegetab les are depended on the presence of other plants in all tested combinations. In this st udy has proven largely inhibitory allelopathic effect on germination and plant growth .
Highlights
Allelopathy is chemical and ecological phenomenon which refers to the fact that competing organisms produce chemicals that inhibit the growth of members of their own or other species (EICHORN et al, 2014).Allelopathy is an interference mechanism in which live or dead plant materials release chemical substances, called allelochemicals, which inhibit or stimulate the associated plant growth (MAY and ASH, 1990)
Because of the extreme importance in recent years which is given to allelopathy in plants important for human consumption, and in order to contribute to a better understanding of allelopathic relationship between certain grains and vegetables, as well as to improving organic production, the aim of present paper was to determine the presence of allelopathic relations during germination of seeds and seedling growth of three cereals and three vegetable species
Cereal seeds are obtained from the Center of Small Grains in Kragujevac and vegetable seeds are bought in agricultural pharmacy
