Hairy roots cultures of Paulownia tomentosa produce verbascoside. The effect of elicitors on verbascoside production in hairy roots P.tomentosa was tested. The following elicitors: yeast extract, methyl jasmonate and salicylic acid were used. The best productivity was obtained in cultures with yeast extract (98,7 mg/g s.m.) and methyl jasmonate (96,4 mg/g s.m).
Using physiologically active, complex, polyfunctional, multicomponent (nano) systems – (nano) chips in the pre-sowing soya treatment (nano) technology allows precise seeding; enhancing field seed germination; reducing plant morbidity rate considerably or even deleting disease incidents; increasing plant adaptability to unfavorable environmental conditions; expanding crop yield; improving products quality by not using toxic chemical means of plant protection; intensifying competitive ability of agricultural products as well as assuring environmental safety in crop cultivation regions.
