Method for the production of seedlings of plant species, which are especially intended for transplanting, such as, for example, of the Solanaceae (tobacco, tomato, pepper, aubergine, petunia, and the like), by "semifloating", that is to say in which the growth substrates containing the seeds or plantlets are placed on a plate which floats on the nutrient solution contained in a tray, the level of which is maintained constant, characterised in that lauryldimethylbenzylammonium bromide (LDBB) is added to the nutrient solution of the tray at a concentration of greater than 0.01% by weight. |
