in order to study the effect of nitrogen on competition between wild oat (avena fatua) and wheat (triticum aestivum) at vegetative growth stage, a factorial experiment was conducted based on completely randomized block design with three replications in research greenhouse of faculty of agriculture, at ferdowsi university of mashhad in 2008. first factor was five densities (0, 2, 4, 6 and 8 plan...
Characterization and Genetic Analysis of a Very High Tillering and Dwarf Rice (Oryza sativa L.) Mutant. (August 2008) Dhananjay Mani, B.Sc. (Hons)., Punjab Agricultural University, Ludhiana, India Co-Chairs of Advisory Committee: Dr. Rodante E. Tabien Dr. Scott A. Finlayson This study focused on characterizing and determining the inheritance pattern of very high tillering and dwarf traits of a ...
Like many other plant RNA viruses, Wheat streak mosaic virus (WSMV) sequence diversity within and among infected plants is low given the large number of virions produced. This may be explained by considering aspects of plant virus life history. Intracellular replication of RNA viruses is predominately linear, not exponential, which means that the rate at which mutations accumulate also is linea...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
The invertases of Lolium temulentum have been characterized at the enzyme level. However, studies on the expression of the genes coding for these enzymes have been lacking. To elucidate the role of acid 'invertase-like' genes in sucrose metabolism and carbon partitioning in Gramineae further, three 'invertase-like' homologous clones were isolated from L. temulentum cDNA expression libraries bas...
This study was conducted to analyze the correlation among grain yield, yield components, duration of vegetative and grain filling periods in twelve oat (Avena sativa L.) cultivars at the Research Farm of the College of Agriculture, Isfahan University of Technology, from 2001 to 2003. A randomized complete block design with three replications was used. The correlation coefficients among the grai...
in order to study the effects of foliar application of si (5/1000 ratio), k (2/1000 ratio) and zn (2/1000 ratio) on rice (cv. tarom hashem), an on-farm experiment carried out based on randomized complete block design with three replications in 2012. some traits such as paddy yield and yield components, neck blast disease and stem borer damage were evaluated. results showed that the effect of fo...
Influence of tiller heterogeneity on yield components of rice grown under different nitrogen regimes
Increase in rice yield under excessive nitrogen (N) supply is negligible, hence it is necessaryto analyze the limiting factors via yield components. The present study was carried out during2014 and 2015 growing seasons in order to quantify the yield componenents of different typesof tiller at various N levels. Tillers were divided into three different types (superior, mediumand inferior) based ...
