Abstract

In the article the brought results over of monitoring research of tendencies of changes of parameters of height and indexes of co-ordination of height of organs at monocotyledonous and dicotyledons plants during forming to the plantlet. Attention paid to influence on the indicated processes of quality of watering water. Monitoring of forming of plantlets monocotyledonous and dicotyledons showed similar orientation of processes of height. Quality of Dnepr water influenced on a height of monocotyledonous plants. Her cleaning assisted a growth acceleration. Monitoring of forming to the plantlet at this class of plants witnessed reliable dependence of co-ordination of height of his organs on quality of watering water. This phenomenon was not observed in dicotyledons. Quality of Dnepr water influenced on the orientation of co-ordination of height of organs to the plantlet only in dicotyledons. Comparative analysis of forming to the plantlet of monocotyledonous and dicotyledons were led to by the different degree of expression of differences during co-ordination of height of him leading organs. In research agricultural plants were range on this index.- Zea mays L.< Triticum aestivum L. <Helianthus annuus L. Comparative analysis of forming to the plantlet two monocotyledonous witnessed different orientation of co-ordination of height of his organs. A corn demonstrated reduction at first, and later is an increase of speed of height of main root relatively coleoptiles and return to the initial level. A wheat showed the gradual increase of values of the indicated parameter during all period of supervision. Research proved that at plants, as well as for animals, there are the stable genetically determined trends of change of proportions of body in early ontogenesis. At plants these trends are species-specific and can be kept in the conditions of action of stress factors of environment. Monocotyledonous wheats and corn are for example. The stress terms of environment can change the orientation of ontogenetic trends of coordination of height of organs of plantlets . A dicotyledonous sunflower showed such trend.
