Effect of sodium azide on growth criteria, some metabolites, mitotic index and chromosomal abnormalities in Pisum sativum and Vicia faba
Seeds of Pisum sativum and Vicia faba were pre-soaked in one of three concentrations (1.0, 2.0 or 4.0 mM) of the mutagenic agent sodium azide (NaN3) for different periods (30 min, 1 h or 2 hs). The impact of these treatments on seed germination, some growth criteria, photosynthetic pigments, some metabolic activities and cytological behavior […]
Allelopathic potential of some essential oils vis-à-vis three noxious weed species invading cereals
This investigation was performed to assess the allelopathic potential of essential oils extracted from seven medicinal and aromatic plants of the Tunisian flora: Artemisia herba-alba Asso., Mentha pulegium L., Rosmarinus officinalis L., Salvia officinalis L., Lavandula officinalis L., Eucalyptus gomphocephala DC. and Foeniculum vulgare Mill.; selected based on ethnobotanical data. To achieve the target, in […]
Role of plant growth promoting rhizobacteria and L-tryptophan on improvement of growth, nutrient availability and yield of wheat (Triticum aestivum) under salt stress
During the present study Pseudomonas sp and Bacillus cereus isolated from rhizospheric soil of halophytic weeds of Khewra salt range were used as bioinoculant on wheat. Aqueous solution of tryptophan was added to the rhizospheric soil @1ug/L after seed germination. Experiment was conducted at Quaid-i-Azam University Islamabad in pots under sterilized condition. Electrical conductivity (EC) […]
Assessment of water quality of drains from irrigation district in a semiarid agricultural zone
Worldwide wastewater is used for agriculture, because of water scarcity. Also, there are increasingly fewer sources of good quality water because of widespread contamination (Ramirez-Fuentes et al., 2002; Rutkowski et al., 2007, Qadir et al., 2010).Agronomic water quality effects on soil, crops and management; major problem with the use of wastewater are salinity, soil permeability […]
Allelopathic inhibitory potential of some crop species (wheat, barley, canola, and safflower) and wild mustard (Sinapis arvensis)
Allelopathic effects of four crops including wheat, barley, canola, and safflower were studied on seed germinations and embryonic growth of wild mustard using different aqueous extract concentrations of the crops. The effects of wild mustard aqueous extracts were also studied on germinations and embryonic growth of the crops. Wild mustard germinations and embryonic growth were […]
Winter wheat (Triticum aestivum L.) allelopathy responses to soil moisture and phosphorus stresses
Field, greenhouse, and laboratory experiments were conducted to evaluate the impact of soil moisture and phosphorus on allelopathic potential of wheat residues, and to study the effect of wheat extract concentrations on the germination and growth of wild mustard (Sinapis arvrnsis L.). The field experimental design was split-plot with 4 replications. The main factor was […]
Use of culture filtrates of Trichoderma strains as a biological control agent against Colletotrichum capsici causing Anthracnose fruit rot disease of chili
Culture filtrates of five Trichoderma strains viz. Trichoderma virens IMI-392430, T. pseudokoningii IMI-392431, T. harzianum IMI-392432, T. harzianum IMI-392433 and T. harzianum IMI-392434 were used as seed treatments aloneand in combination with culture filtrates of Colletotrichum capsici, to assay their efficacy in suppressing Anthracnose fruit rot disease and promoting chili plant growth and yield, under […]
Genetic variability study for yield and associated quantitative characters in mutant genotypes of Dianthus caryophyllus L.
The present study was conducted to evaluate the nine Dianthus genotypes, including normal and mutagen treated, to assess the magnitude of variability and to pick up the heritable component of variation present in the quantitative traits. The analysis of variance revealed highly significant (P< 0.05 or 0.01) differences for all the characters studied, indicating the […]
Understanding growth patterns of mung beans (Vigna radiata) through polynomial interpolation: Implications for cultivation practices
This study aims to explore the germination and growth patterns of mung bean seeds (Vigna radiata) through a polynomial interpolation fitting approach in a controlled environment. Mung beans are also popular in Asian diets, are used in many dishes, and have lots of nutritional value. The study is meant to describe the germination and growth […]
Effects of gibberellic acid on potato (Solanum tuberosum L.) growth and development during off-season cultivation
Solanum tuberosum L. (potato) is a crop in temperate regions, exhibiting exceptional food productivity and adaptability. Plant hormones can be used to increase the yields. Gibberellic Acid 4+7(GA4+7) is a plant growth regulator which can increase germination rate of some seeds and induce leaves. In this study, Potato tubers were treated with different concentration of […]
