Biocontrol agents isolated outside Africa have performed inconsistently under field conditions in Africa. The development of indigenous phytobeneficial microbial strains that suit local environments may help enhance competitiveness with in situ microorganisms and effectiveness at suppressing local pathogen strains. We isolated bacteria from the rhizosphere of maize growing in southwestern Niger...

Lotus nelumbo (LN) (Nelumbo nucifera Gaertn.) is an aquatic crop that is widely distributed throughout Asia and India, and various parts of this plant are edible and medicinal. It is noteworthy that different organs of this plant are used in traditional herbal medicine or folk recipes to cure different diseases and to relieve their corresponding symptoms. The compounds that are contained in eac...

The relationship between the apical hook and stem nutation in etiolated Alaska pea (Pisum sativum L. cv Alaska) seedlings was explored. The hook and maximum nutational displacement have the same plane of symmetry, and both are affected by light acting through phytochrome. However, the two processes do not appear to be obligatorily coupled. Light effects on nutation involve at least two componen...

Seeds and young seedlings of wheat (Triticum aestivum L.) under exposure to Copper (Cu), lead (Pb) and Zinc (Zn) were studied by employing a hydroponic experiment. Addition of Cu or Pb or Zn to the solution inhibited seed germination, plumule and radicle elongation. The toxic of metals to seed germination parameters can be arranged in the rank order of inhibition as follows: Cu > Pb >> Zn. This...

Environmental stress, especially drought stress, can play an important role in the reduction of the plant growth stage, specifically duringgermination in arid and semi arid regions in Iran.. In order to study the effects of drought stress on germination indices in wheat cultivars, an experiment was conducted in factorial form, using a completely randomized design of four replications. In this e...

Large quantities of oil and gas well brines are produced annually in Ohio. This paper presents chemical parameters measured for a Wayne County, Ohio, oil well brine and reports the effects of several incremental brine concentrations on the germination and seedling development of soft red winter wheat (Triticum aestivum), soybeans (Glycine max), tall fescue (Festuca arundinacea), garden peas (Pi...

In this study, the effect of seed priming using ascorbic acid (ASA) on three commercial wheat cultivars i.e., Punjab-2011, Faisalabad-2008, and Ujala-2016 under salinity stress in both homogenous heterogeneous environments has been investigated. It revealed that different levels have significantly reduced growth attributes like percent germination, germination index, radical & plumule length, v...

An experiment was carried out at the Department of Field Crops laboratory, College Agriculture, University Tikrit, in order to know effect stimulating stored seeds triticale Farah cultivar by α -amylase enzyme using a complete random design (CRD) factorial experiment. The first factor storage periods 6 months, 1.5 years and 2.5 (S1,S2 S3) second concentrations 0 (dry seeds), soaked distilled wa...

Present study was conducted to investigate whether plant growth regulators viz. salicylic acid and ascorbic acid can alleviate the adverse effects of drought stress on germination and seedling growth of two sunflower hybrids (Hysun-33 and Hysun-38). Two (-0.06 MPa and -0.12 MPa) levels of drought stress were created by adding different concentrations of (PEG8000) polyethylene glycol in growth m...
