Rumex palustris responds to complete submergence with upward movement of the younger petioles. This so-called hyponastic response, in combination with stimulated petiole elongation, brings the leaf blade above the water surface and restores contact with the atmosphere. We made a detailed study of this differential growth process, encompassing the complete range of the known signal transduction ...

background and objectives:  hawthorn is a forest fruit tree which is grown in the temperate regions around the world. this plant is known as the most traditional herbal remedy for heart failure and cardiovascular disease in worldwide. this study has been conducted to investigate the genetic variability and classify hawthorn genotypes based on quantitative and qualitative characteristics of leaf...

Among a French collection of 150 Diaporthe helianthi / Phomopsis helianthi Munt.-Cvet. isolates collected on sunflower since 1995, 4 were chosen for their different characteristics according to their geographic origin and the part of the infected plant where they were sampled (leaf, petiole, capitulum). Phenotypic and molecular characterisation studies were conducted on these isolates. Phenotyp...

Toddalia aculeata (Syn. T. asiatica, T. rubicaulis, T. nitida and Scopolia aculeata) is a climbing shrub of natural order Rutacea. Vernacular, Sanskrit, kauchana; Hindi, kanj; dahan lalian (Rajputana); meinkara (Nepal); saphijirik (Lepclia); melkaranai kandvi (Tamil); konda-kathinda (Telegu); janglikali-mirchi (Bombay); kudur-7niris (Ceylon). It grows in sub-tropical climates of India, Java, Su...

The study aimed to investigate the effects of mycorrhizal inoculation on growth and development; three plant species: Petunia hybrida, Antirrhinum majus, Dianthus chinensis. as well heavy metals in soil. measured various parameters such shoot fresh weight, root flower numbers, length, diameter, leaves number, petiole length. Results showed a significant increase weight 10.74 g, weight1.77g, num...

Castor, (Ricinus communis L.) is one of the most important commercial, non-edible oilseed crop. Tobacco caterpillar, Spodoptera litura (Noctuidae: Lepidoptera), a major defoliator castor. The biophysical factors in castor play role conferring resistance against S.litura. present study was conducted with an objective, to basis S. litura. Feeding preference larvae leaves IVHT-39 followed by Salem...

A new genus and species of myrmeciine ants, also called bulldog is described illustrated from the Palaeocene Menat (France) as Tyrannomecia inopinata gen. et sp. nov. This taxon represents oldest representative subfamily provides calibration point for total clade Myrmeciinae. It shows apomorphic characters used to define Myrmeciinae: mandibles elongate such that their length three-quarters or m...

Plants grown under a canopy recognize changes in light quality and modify their growth patterns; this modification is known as shade avoidance syndrome. In leaves, leaf blade expansion is suppressed, whereas petiole elongation is promoted under the shade. However, the mechanisms that control these responses are largely unclear. Here, we demonstrate that both auxin and brassinosteroid (BR) are r...

Abstract The strawberry growth and fruit yield of five Korean cultivars in the tunnel-type greenhouse predicted using their growth. number leaves, petiole length, leaf length width, crown diameter, ratio red far-red (RFR) were measured during cultivation period. leaves all exhibited a similar trend this period; plant ‘Maehyang’ longest, trends except for ‘Jukhyang’, width ‘Arihyang’, was diamet...

Transport and metabolism of IAA-1-(14)C in Coleus blumei Benth. was studied by means of a combination of liquid scintillation counting, autoradiography and thin-layer chromatography. Transport of IAA in petiole segments of increasing age (No. 2-8) was strictly polar in a basipetal direction. No acropetal movement occurred in either young or old tissues. The greatest amount, expressed as a perce...
