BACKGROUND AND AIMS The objective of this study was to test whether the mean values of several root morphological variables were related to the ability to develop root-borne shoots and/or shoot-borne roots in a wide range of vascular plants. METHODS A comparative study was carried out on the 123 most common plant species from eroded lands in north-east Spain. After careful excavations in the ...
The Silybium marianum is the dicotyledonous herbs of the Asteraceae family that is important in medical industry. The biological active compound of Silybium marianum is a mixture of several flavonolignals generally known as silymarin. The purpose of current research is root formation induction in hypocotyls explants in medium culture. The young shoots were cultured on MS medium containing diffe...
To evaluate the commercial and local cucumber rootstocks in grafting conditions at different nitrogen (N) levels and temperatures of the rootzone, this research was conducted for a year in the Research Greenhouse of the Department of Horticulture, College of Agriculture, Isfahan University of Technology in 2014. The research was a factorial experiment based on completely randomized design with ...
Seedlings of Betula pendula Roth were grown with their root systems separated between two soil compartments. Four treatments were imposed: (i) adequate irrigation in both compartments (WW, controls); (ii) adequate irrigation in one compartment and drought in the other compartment (WD); (iii) drought in both compartments (DD); and (iv) half of the root system severed and the remainder kept well-...
● Background and aims. The objective of this study was to test whether the mean values of several root morphological variables were related to the ability to develop root-borne shoots and/or shoot-borne roots in a wide range of vascular plants. ● Methods. A comparative study was carried out on the 123 most common plant species from eroded lands in NE Spain. After careful excavations in the fiel...

This study was conducted to evaluate the effect of plant growth regulators on in vitro shoot multiplication, vitrification and rooting of two carnation cultivars (Eskimo Mogr and Innove Orange Bogr). Isolated axillary buds were cultured on MS medium supplemented with different levels of Benzyl amino purine (BAP) or kinetin (Kin) in combination with 0.2 mg/l NAA and shoot multiplication and vitr...
Root hairs, which arise from root epidermal cells, are tubular structures that increase the efficiency of water absorption and nutrient uptake. A low pH (pH 4) medium induced root hair formation in lettuce (Lactuca sativa L.) seedlings, and the decapitation of shoots inhibited root hair formation. The addition of shoot extract to the medium restored root hair formation in the decapitated lettuc...
The phytotoxicity of Se(IV) was determined through root and shoot growth inhibition, biomass (dry (DM), fresh (FM)) production, water content, photosynthetic pigment (chlorophyll a, chlorophyll b and carotenoids) levels and Se accumulation in the roots and shoots. The sensitivities of monocotyledonae (Hordeum vulgare, Triticum aestivum) and dicotyledonae plants (Sinapis alba, Brassica napus) we...
Concern over poisoning as a result of eating cassava roots or shoots has led to these studies to determine factors which lead to high cyanide content in these tissues and how detoxification can be carried out. Plant age or stage of development does not seem to have a clear influence on root or shoot cyanide content. Genetic control on cyanide content seems significant as varieties may be identi...
