Somatic embryogenesis and plantlet regeneration of pummelo ‘Nambangan’ (Citrus maxima (Burm.) Merr.)
Somatic embryogenesis is a method which needs to be mastered to support plant breeding in biotechnology. The induction of somatic embryos from various explants could be regenerated into plantlets. The aim of this study to establish somatic embryogenesis and plantlet regeneration of pummelo ‘Nambangan’, one of the local prime fruit varieties in Indonesia, from various […]
The effect of tetrazolium and rubbing on dormancy breaking in Beans
Seed dormancy is a resting condition of plant seeds that control germination under extreme environmental conditions. True dormancy is due to conditions in the seed that prevent germination in normally ideal conditions. Tatrazolinm is a chemical which has an effect on breaking dormancy, another way of breaking the seed dormancy is a mechanical method like […]
Metabolic response of tomato (Lycopersicon esculentum Mill.) under salt stress combined with hormones
Effect of the combined the phytohormones-salinity (ABA, salicylic acid and GA3) on the total soluble protein and soluble sugars content contained in germinated seeds of two tomato varieties (Lycopersicon esculentum Mill.) is realized to characterize the soluble metabolite involvement in the processes of adaptation to salinity. The research of plant species tolerant to salinity requires […]
Natural plant based solution for industrial wastewater
In developing countries like Pakistan, industries are increasing rapidly and are reluctant to manage industrial wastes and wastewaters. This industrial wastewater (IWW) containing number of toxic chemicals, which join natural water streams to disturb the whole ecosystem. Among physical and chemical methods to treat IWW, nature based systems are gaining popularity being more eco-friendly, less […]
Evaluation of an important flavonoid silymarin in callus cultures of Sylibum marianum (L.) Gaertn
Silybum marianum L. Gaertn is an important medicinal herb due to its active secondary metabolite, silymarin pronounced to be effective in disturbed liver function and ailments. The plant is under harvest pressure for sylimarin production and is being endangered. With the objective to produce silymarin in vitro, seed germination were optimized maintaining aseptic conditions. Seedlings […]
Identification of tomato (Lycopersicon esculentum L.) genotypes for salt tolerance during emergence
Salinity in soil or water is one of the major stresses that affect crop production around the world. In Bangladesh the coastal areas are increasing day by day due to climate change. Therefore it is very important to investigate the mechanisms of salt tolerance. That is why, this study was undertaken to investigate the effect […]
Evaluation of phosphodissolvent IAA producing strains of Trichoderma, spp. through biometric response of Phaseolus vulgaris L
Studies report that in addition to biocontrol effects, Trichoderma spp., exhibit phosphodissolvent and indole acetic acid (IAA) production capacities. In greenhouse laboratory conditions, the effects of four native strains of Trichoderma spp., were evaluated on the germination and growth of beans. Inoculants of each strain were prepared in concentrations of 104, 106, and 108 spores […]
Effectiveness of two diatomaceous earths (FossilShield® and SilicoSec®) against Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae) infesting two maize varieties (CLH103 and SHABA) at storage
Influence of maize varieties CLH103 and SHABA on the effectiveness of FossilShield® and SilicoSec® against Sitophilus zeamais was evaluated in laboratory. Each product was used at 0, 0.5, 1, 1.5 and 2 g/kg and four exposure periods (1, 3, 7 and 14 days) for adult mortality and F1 progeny production. Damaged and germinated seeds were […]
Effects of some environmental factors on annual weed shepherd’s purse (Capsella bursa-pastoris (L.) Medik.)
Shepherd’s purse (Capsella bursa-pastoris (L.) Medik.) is an annual weed species with a wide distribution in cereals of East Azarbaijan, Iran. Tow experiments were carried out based on randomised complete block design with four replications in Tabriz, Iran in 2014 to evaluate the effects of salinity and drought stress on shepherd’s purse germination and early […]
Response of maize (Zea mays L.) to sodium chloride concentrations at early growth stages
The present study was conducted to investigate the effect of NaCl concentrations on seed germination and seedling growth of maize (Zea mays L.). Laboratory and pot experiments were conducted in 2014 using maize seeds obtained from Ministry of Agriculture Central Darfur State, Sudan. Ten seeds were germinated in Petri dishes containing filter paper of 9cm […]
