Heliotropium kotschyi (Ramram), is a very important plant in relation to environment protection and for its medicinal value in Bahrain. It has been detected as one of the endangered plants in Bahrain. Ex situ conservation of this plant applying tissue culture method was used in the present study. In vitro plant regeneration has been established via shoot organogenesis using nodal meristems. The...

background & aim: dracocephalum genus belongs to the lamiaceae family which has eight species in iran. dracocephalum kotschyi boiss is an important medicinal and aromatic plant that use in pharmaceutical industry. in addition, this species is used in iranian traditional medicine. the aim of current study was to examine the various growth regulations and explants on direct organogenesis of d...

Omega-3 fatty acids containing microalgae are considered a promising feedstock for food and nutraceutical applications. To meet the commercial nutritional demands of essential omega-3 acids, different strategies being implemented, including supplementation plant growth regulators (PGRs). In present study effects selected, PGRs, i.e., gibberellic acid (GA), salicylic (SA), malic (MA; TCA cycle i...

this review article investigates a comprehensive description of the factors, methods, strategies, approaches and prerequisites influencing in vitro micropaopagation and the amount of their use across the world. the findings presented here are the results of the study of several hundred papers published all over the world. tissue culture techniques are routinely used for micropropagation. enhanc...

Lodging is one of the main factors causing yield loss maize under high-density planting conditions. Root lodging as an important type has received little attention. Plant growth regulators (PGRs) and nitrogen fertilizer can coordinate relationship between root yield. This two-year field experiment was conducted with two levels N225 (225 kg ha−1) N300 (300 at a high density (90,000 plants during...

Natural and synthetic plant growth regulators have been used with increasing frequency to modify crop plants by changing the rate or pattern, both, of their responses internal external factors that govern development from germination. The use (PGRs) in modern horticulture is well established, particularly industrially advanced countries, application fast picking up developing nations as well. r...

In cork oak (Quercus suber L.), recurrent embryogenesis is produced in vitro through autoembryony without exogenous plant growth regulators (PGRs); secondary embryos appear on the embryo axis but seldom on cotyledons. Focusing mainly on the histological origin of neoformations, we investigated the influence of the embryo axis and exogenous PGRs on the embryogenic potential of somatic embryo cot...

the present work developed an efficient plant regeneration and propagation system via direct organogenesis for morinda officinalis how., a valuable endangered medicinal plant. the effects of explant types on shoot induction, plant growth regulators on shoot proliferationand elongation and the subsequent rooting ability of shoots were examined. among the various types of explant, direct shoot pr...

Abstract Salinity stress and the absence of light negatively impact growth development plants. Morpho-physiological biochemical attributes maize ( Zea mays L.) get severely affected by salt subdue light. Therefore, a pot experiment was conducted under prevailing environmental conditions Turbat, Balochistan, to explore etiolation de-etiolation response hybrid (SP-17S23) salinity exogenous applic...

Salinity is one of the most important limiting factors in plant growth. It also a predominant constraint that impairs grass growth and quality. Plant hormones play roles capability plants to adapt environmental stresses. Hence, impact two regulators (PGRs) i.e. salicylic acid (SA) progesterone (P4) was studied on biological characteristics Poa pratensis saline conditions greenhouse experimnt. T...
