The study was made in order to evaluate the response of fifteen wheat genotypes (grown in Pakistan) to sodium chloride salinity at seedling stage keeping two levels of salinity (150 and 200 mM NaCl) along with a control (no application of salt). The effect of varieties on shoot length of wheat was non significant. Maximum shoot length was recorded in MH-97 (15.55cm) while minimum shoot length w...

BACKGROUND AND AIMS It is generally assumed that plants respond to natural enemies by either allocating resources to resistance traits or compensating for damage. This study evaluated how different methods of artificial shoot removal influence two alternative strategies (i.e. tolerance and defence) of Caragana korshinskii in the semi-arid area of China. METHODS Zero per cent (control), 30% (3...

in order to study the effect of soil compaction on root and shoot growth of wheat plants (shahriar variety), a greenhouse pot experiment was conducted in guilan university. the study design was factorial with completely randomized in three replications. treatments included three compaction levels; (normal compaction, compaction of ten percent and twenty percent) and two type of soil texture (cl...

Shoot tips of two fig cultivars (Conadria and Black Mission) proliferated in vitro, were cultured on modified MS medium supplemented with 0.5 mg/l 6-benzylaminopurine (BAP). The present investigation aimed to investigate the effect of different medium salt strengths (Double, full, half and quarter) and different sources of carbon (sucrose and fructose) at different concentrations (0.1 and 0.2 m...

We have identified certain heat-resistant (HR) and heat-sensitive (HS) lettuce (Lactuca sativa) recombinant inbred lines (RILs) from 113 lines under hot ambient temperature by studying the root morphology, shoot and root productivity. Except for temperature, one of the other major determinants of root morphology is nitrate (NO3 ) availability. In this study, total productivity, root morphology,...

Effects of relative shoot height and irradiance on shoot and leaf properties of Quercus serrata Thunb. saplings growing in the understory and in gaps were investigated. Photosynthetic photon flux (PPF) at the location of the shoot relative to that in the open (relative PPF; rPPF) and the height of the shoot base relative to tree height (relative height; rHeight) were measured for all current-ye...

Nursery experiments were conducted to select the suitable biofertilizers combination attain quality seedlings of Neem. The such as Azospirillum, Paenibacillus and AM fungus (Glomus fasciculatum) inoculated by separately various combinations with each other at time seed sowing. Shoot length, root collar diameter, shoot dry weight recorded on 80 days after treatment. Results showed that total len...

in order to evaluate the effect of different irrigation intervals on some morphophysiological traits of sesame (sesamum indicum l.), an experiment was conducted under greenhouse conditions during 2009. the experiment was based on a randomized completely design with three replications. treatments included four irrigation intervals with 4, 8, 12 and16 days intervals and two ecotypes of sesame (ka...

Effects of additional nitrate (20 mol m·3 NO;) on growth of barley (Hordeum vulgare L. cv. Triumph), oat (Avena sativa L. cv. Amuri), rye (Secale cereale L. cv. Rapaki), triticale (x Triticosecale Wittm. cv. Aranui) and wheat (Triticum aestivum L. cv. Otane) prior to emergence from a sowing depth of 70 mm were examined under controlled environment. conditions. For all five cereals, additional N...
