BACKGROUND Bioenergy sorghum accumulates 75% of shoot biomass in stem internodes. Grass stem internodes are formed during vegetative growth and elongate in response to developmental and environmental signals. To identify genes and molecular mechanisms that modulate the extent of internode growth, we conducted microscopic and transcriptomic analyses of four successive sub-apical vegetative inter...

a trial study was set to assess the influence of the plant residue management in conjuction with application of different nitrogen sources on accumulation and translocation of wheat stem reserves, at the agricultural faculty of shahid chamran university of ahvaz during 2011-2012. the experimental design was split plot at randomized completed block design arrangement. the main plot were differen...

stem reserves of barely can be an important contributor to grain filling particularly under condition is limited such as salinity stress. the aim of this research was to study dry matter accumulation and remobilization ability in different internodes of some iranian barley varieties and promising lines under salinity and normal conditions. the research was set up as two randomized complete bloc...

A sensitive, specific enzyme immunoassay (EIA) for trans-zeatin riboside (ZR) and trans-zeatin (Z) in the 0.3 to 30 picomole range has been described. The reliability of the method for measuring ZR + Z in partially purified extracts of Zea mays L. tissues was verified by highperformance liquid chromatography. EIA measurements showed that there was a concentration gradient of ZR + Z along the le...

In the course of field and laboratory research, selection samples spring hexaploid triticale were studied for their selection-valuable traits lodging resistance. The correlation analysis revealed a between individual that determine tolerance. most stable relationship resistance is with length second third internodes breaking strength straw. An additional criterion sum lengths 2nd 3rd internodes...

The cellular mechanisms that regulate the topographic arrangement of myelin internodes along axons remain largely uncharacterized. Recent clonal analysis of oligodendrocyte morphologies in the mouse optic nerve revealed that adjacent oligodendrocytes frequently formed adjacent internodes on one or more axons in common, whereas oligodendrocytes in the optic nerve were never observed to myelinate...

Merremia emarginata plants were treated with different plant growth regulators (PGRs): naphthyl acetic acid (NAA), phenyl acetic acid (PAA) and gibberellic acid (GA 3). To determine the role of wall stiffening enzymes in internode elongation, IAA oxidase and peroxidase in the presence of different hydrogen donors like caffeic acid, chlorogenic acid and guaiacol were assayed. The levels of total...

to investigate the effect of spraying with different concentrations of vermiwash solution on the morphological traits, percentage and yield of essential oil of lemon balm (melissa officinalis l.), this experiment was conducted as randomized complete block design (rcbd) with four replications in experimental field of agricultural faculty of ferdowsi university of mashhad (fum). the treatments we...
