pistacia atlantica is the most important tree species for the economy of many rural areas in west of iran, but no effort has been made for the genetic improvement of this species. the aim of this investigation was to study the genetic variation and inheritance of early growth traits in p. atlantica. for this purpose, three wild pistachio populations comprising 60 randomly selected adult trees f...

Bacillus subtilis strain LPM1 was previously documented as a plant growth-promoting rhizobacterium under open field conditions. For deeper understanding, the present study established in shade house with three different commercial varieties of bell pepper (Prosperity RZ, Valkiria and Sven RZ) treated prior to transplanting B. LPM1. The trial performed parallel experiments (one per variety) comp...

ABSTRACT Some vegetables have been used as an innovation in the ornamental plant market, such cauliflower, which has well-defined morphological traits. This study aimed to evaluate effect of paclobutrazol, applied via soil, order produce cauliflower for purposes. The design was completely randomized with five treatments and seven replicates. consisted doses growth regulator paclobutrazol (PBZ) ...

in order to reduce consumption of chemical fertilizers and in order to evaluate the effect of biofertilizers on yield and yield components of sunflower nuts (helianthus annuus l.), the research was carried out with using factorial based randomized complete block design with three replications at agriculture and natural resources researches station of khoy in 2011. the first factor was  three su...

Many agriculturally important traits are complex, affected by many genes and the environment. Quantitative trait loci (QTL) mapping is a key tool for studying the genetic structure of complex traits in plants. In the present study QTLs associated with yield and agronomical traits such as leaf number, leaf length, leaf width, plant height, stem and head diameter were identified by using 70 recom...

the present experiment was carried out to assess the general combining ability (gca) and specific combining ability (sca) of six important commercial cultivars of gossypium hirsutum l. of venezuela, viz., ‘deltapine 16’, ‘tamcot-sp-21’, ‘cabuyare’, ‘stoneville’, ‘ospino’ and ‘acala 90-1’ and their 15 f1 hybrids, respectively. the data were analyzed using griffing’s model i method ii. significan...
