Induction of Striga hermonthica germination and haustorium initiation by Allelochemicals produced by millet cultivars
Laboratory experiments were conducted to evaluate the allelopathic potential of 16 millet cultivars on early developmental stages of Striga. Millet leaves and roots residue dry matter powder with different level was used for the bioassays on Striga germination and haustorium using Fuji techniques. Result revealed that leaves residue of the cultivar DST displayed the highest […]
Response of germination parameters of some canola cultivars to salinity stress
A laboratory experiment was conducted at Agronomy Department Laboratory of Seed Testing, Faculty of Agriculture, Mansoura University, Egypt, during December 2013 to study the effect of salinity concentrations on germination and seedlings parameters of some canola cultivars. The aim of this experiment was the study performance of three cultivars of canola i.e. Serw 4, Serw […]
Assessment of allelopathic potential of different weeds on germination and early growth of aromatic rice
An experiment was carried out at the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh during the period from July to November 2011 to investigate the allelopathic potential of different weeds on aromatic rice cv. BRRI dhan 50. Six weed species viz., joina (Fimbristylis miliacea), mutha (Cyperus rotundus), khude shama (Echinochloa colonum), sobuj nakful (Cyperus […]
Effect of drought stress on germination in 18 population of thyme (Thymus kotschyanus)
Thyme is an important medicinal plant of Iran that have Thymol and Carvacrol and used for antimicrobial and antibacterial agent. The present study was carried out to determine the effect of drought stress in 18 populations of this species. The environmental stress such as, drought are serious obstacles for medicinal plants and field crops in […]
Quality assessment of yard long bean (Vigna unguiculata) seeds through the controlled deterioration technique
A three-factor experiment was conducted at the Horticulture Laboratory, Hajee Mohammad Danesh Science and Technology University, Dinajpur during April- May 2014 to study the effects of the controlled deterioration (CD) on the yard long bean seed quality at the constant temperature of 350C to assess the physiological seed quality of both the two cvs. The […]
Germination response of endangered medicinal plant, Levisticum officinale, to stratification and some plant growth regulators
Levisticum officinale is an important and endangered wild medicinal plant belongs to Apiaceae family. Pre experiment showed that seeds of this plant have some degree of dormancy and it‘s germination is very low. Therefore, a factorial experiment laid out in completely randomized design with 3 replications to evaluate the effect of different plant growth regulators […]
Germination of the tomato (Lycopersicon esculentum Mill.) in response to salt stress combined with hormones
Salt stress is a major environmental constraint most limiting plant productivity. Seeking salt-tolerant crops requires an examination of the behavior of the plant development including seed germination stage. The effects of NaCl stress (100 mM) combined or not with different solutions of phytohormones ABA (0.005 mM), GA3 (0.005 mM) and SA (0.5 mM) on germination […]
The survey of the effect of the acceleration aging and cold pretreatment on germination and other factors of the plantlet growth in two varieties of canola
One of the most important problems with oily plants like canola is their storage. Because if the storage of the seeds is not suitable the seeds will oxidize as they are oily and they lose their germination ability much faster than the seeds of the other plants. Therefore to assess the effect of cold and […]
Investigating the effect of drought stress induced by mannitol on germination and morphological properties of wheat inbred lines
To investigate the response of inbred lines of M82 and Babax wheat series to drought stress, which induced by mannitol, on growth stage of plant, a factorial experiment with a completely randomized design with 2 replicates in normal and drought stress condition on 169 in board lines, was performed. Ln this research the mannitol with […]
Germination percentage and growing behavior of Salix tetrasperma (Willow) as affected by size of branch cutting and low polythene tunnel
Propagation through branch cuttings is one of the best methods to produced tree nursery the yield of the tree produced from a cutting can be higher then a tree produced from seedlings, the conditions provided to them are important factor for getting good results. The aim of this study was to find the best size […]
