A method for the production of plants by means of flotation system, in particular for the heat-setting, for example plants of the genus nicotiana

摘要

Process for the production of plants of plant species, in particular intended for the subculturing, such as, for example nicotianées (tobacco, tomato, garden capsicum, aubergine, petunia etc...) by "semi floating ", that is - to - say in which the substrates containing the seeds or the plantlets are placed on a plate, which floats on the nutrient solution contained in a tank whose level is maintained constant, characterized by the fact that there is added to the nutrient solution of the tank of lauryl dimethylbenzylammonium bromide (bldb) at a concentration greater than 0,01% by weight.
