More sensitive than Mimosa pudica and more beautiful than any adornment detached from nature by man, the azalea (Azaleea
indica) gathers through its shapes a real symphony of colours and enchanting hues, of elegant shapes, having no rival in the flower world.
The azalea can multiply through seeds and vegetatively: seedlings, grafting, lay...ering.
The widest reproduction method remains that through semilignified seedlings, a method that can be used throughout the year
avoiding the months less favourable for propagation by seedlings, with poor light: November and October. The best results are given by the
spring propagations by seedlings (February-March) and the summer propagations by seedlings (July-August). The rooting can last for 12-14
weeks until the seedlings can be transplanted in flower pots without risks.
A wide application in horticultural practice is the use of growth substances, that take part in the faster formation of roots and in a
higher percent for species of plants, that, normally, root with difficulty through seedlings. Under this aspect, many synthetical compounds
have proved to be very active (IAA, NAA, IBA, 2,4,5-T acid etc.) (3,4).

An important problem refers to soil weeds seed bank with special reference to brown luvic soils and relationship between vegetal remains
(roots + stub) and nutrition regime – crop rotation plant. A great number of seeds can be found in first 20 centimeters of soil (plowing
layer). This fact causes a high weeds density, which has a negat...ive effect on the cultivated plants leading to partial or total crop loss.
