The Growth Regulators and Micronutrients Role Under the Herbs Introduction in to Culture

Abstract

With the introduction of new species of medicinal plants there is a change in their usual ecological condition. Unstable weather conditions and phytopathogens can have a negative influence on crop yields. In this article discussed some aspects exogeny management of adaptation processes for new introduced medicinal plants: Lycopus europaeus L., Arctium lappa L., Serratula coronata L. Application of plant growth regulator Dvau for rooting cuttings and binary mixtures of growth regulator Zircon and organomineral (Absolute,Ecofus) or silicon fertilizers (Siliplant) in fields on gypsywort promotes resistance to adverse weather conditions and reduced crop losses in low moisture and high temperatures of 16-20%, with high humidity and low temperature – 23-25%. On greater burdock it is shown that insufficient water supply has a negative impact on growth processes: the area of the assimilating surface of plants decreases by 17%, the mass of roots - by 13%. Double treatment of plants with silicon-containing microfertilizer Siliplant eliminates the negative impact of drought and increases the yield of roots (medicinal raw materials) by 17-18%. Abiotic and biotic stresses can have a negative impact on the yield and quality of medicinal raw materials of Serratula coronata. Application of microfertilizer Ferovit in dry weather conditions increases the area of the assimilating surface by 28-30%, the yield of raw materials (grass) by 20-25%. One of the biotic stress on Serratulais is the defeat of plants by powdery mildew (Erysiphe cichoracearum D.C.). Complex application of the growth regulator Zircon and microfertilizer Ferovit provided a more rapid passing of phenological stages, which allowed to begin the harvest before plants defeat by powdery mildew and to exclude from the agrotechnology the use of fungicides.

Exogenous regulation of biological productivity of fenugreek

“…In order to increase productivity, we used a binary mixture of organic fertilizer "EcoFus" (5 ml/L) and "Siliplant" microfertilizers (1 ml/L), which have proven themselves in medicinal plants [15,16].…”

Effect of integrated use of Zircon and Siliplant on productivity of <i>Echinacea purpurea</i> roots in Western Caucasus

“…В литературе вопросу повышения урожайности корней лекарственных культур посвящены лишь единичные работы. Так, при обработке Силиплантом вегетирующих растений синюхи голубой и лопуха большого урожайность корней повышалась на 16% и 18%, соответственно [8,9]. Применение Циркона при вегетативном размножении облепихи, шиповника, белладонны, мелиссы обеспечило высокую приживаемость черенков и активизацию роста корней [10].…”

Increasing the bioproductivity of Ammi majus L. with the use of growth regulators and microfertilizers

“…The use of natural growth regulators is especially important in the cultivation of medicinal crops, since they are characterized by low seed germination energy, a long germination period, and a weak growth response at the initial stages of ontogenesis [5]. As noted by N. I. Sidelnikov et al, the use of growth regulators of organomineral and microfertilizers helps to enhance the growth processes of new introduced medicinal plants, increase adaptation to unstable weather conditions and obtain stable yields with a high content of active substances [14].…”
