THE STUDY OF THE DEVELOPMENT OF THE ROOT SYSTEM ON FEW CONIFERS AND ON SOME VARIETIES OF SHRUBS
The studying of the growth and development of the root system is a matter of greatÂ interest for all the crops in the country. Observing the development of the root systemÂ suggests the mechanical work that must be applied in order to avoid the damaging of theÂ roots.Â
The role of the root system is to absorb water, nutrients and to fix the soil. In theÂ case of varieties of shrubs studied we can mention that on the same type of soil, theÂ varieties of raspberry and blackberry roots have reached the depth of 25 cm, the redÂ varieties of gooseberries, red currant and black currant to a depth of 15 cm.
Studying the roots taken out of the pots of the varieties of conifer, Thuja occidentalisÂ holmstrup, Thuja Smaragd and Thuja Columnaris we could notice that they reached to aÂ depth of 15-18-20.0 cm. The development and root growth generally depends onÂ environmental factors, on the species, on the variety, on rootstock and also on agricultural
