Early growth stages structure and distribution of Pericopsis elata (Harms) van Meeuven in a logging concession of South – East Cameroon
Pericopsis elata (Harms) van Meeuwen is a tropical Africa’s timber of high economic value. In many countries its low natural regeneration rate does not favor the replacement of harvested populations, thus CITES and IUCN recommended a total protection of the species. This survey aimed to characterize the early growth stages and natural regeneration of P. […]
Identification and Study of cis regulatory elements and phylogenetic relationship of TaSRG and other salt response genes
Salt stress is the major limiting factor in agriculture that affects on all developmental stages including germination, seedling and vegetative stages. Under salt stress, induce the expression of many plant genes. These genes encode the defending proteins, and regulatory proteins that regulate the stress signal transduction. The TFs interact with cis-elements in the promoter regions […]
The study of adaptability and results of medicinal plants cultivation in the conditions of Fars province collection
This research was aimed at studying economical and functional considerations, creating live gene bank of medicinal plants (collection) as well as investigation of collective cultivation and breeding of aborigine and exotic species for scientific and investigative considerations to be applied in educational, investigative, and administrative situations. It also was aimed at preventing the genetic extinction […]
Application of biophysical and biochemical methods as priming techniques on Carthamus Tinctorius L.
For disclosing the effects of seed priming with biophysical and biochemical methods on yield and other characteristics on safflower (Carthamus Tinctorius L.), the seeds of one safflower cultivar was treated with 72 mT strength for 10 min, hydro priming for 72 hours and gibberellic acid with 50ppm concentration for 8hours before germination and cultivation. In […]
Effects of fresh leaf materials of Sesbania sesban (L.) Merrill on the growth and photosynthetic pigments of nightshade (Solanum nigrum L. var. popolo)
Solanum nigrum L. is one of the African leafy vegetable consumed in Kenya. High cost of inorganic fertilizers has made it inaccessible by smallholder farmers leading to low yields. A study was conducted at Maseno University, Kenya to investigate the effects of Sesbania sesban fresh leaf materials on the growth of Solanum nigrum L. The […]
Phytoavailability of chromium in Triticum Aestivum in natural and synthetically fertilized soil irrigated with hudiara drain wastewater, Lahore
The present study compares the phytoavailability of chromium (Cr) in the presence of natural (kitchen compost) and synthetic (commercially available urea) fertilizers in Triticum aestivum. To achieve this, the contaminated water was collected from selected sites of Hudiara drain following random sampling technique. The collected water samples were combined to give homogeneous mixture of representative […]
Responses of slenderleaf rattlebox (Crotalaria ochroleuca) to water deficit
Water deficit affects plant growth and development thus affecting crop productivity. It is the major a biotic stress experienced in the vast semi arid and arid regions of Kenya and the world as a whole. Water deficit mainly causes reduction in plant growth and development. Crotalaria ochroleuca is an important indigenous leafy vegetable which is […]
Analysis of the relationship between root morphology and uptake of fertilizer nitrogen in rice (Oryza sativa L.)
Due to the roles of root in water and mineral uptake, it is one of the most important organs for plant growth. In order to analyze the morphological differences of the root in four Iranian cultivars of rice (Tabesh, Fajr, Tarom-e-Mahali and Neamat cultivars) and their relationship with nitrogen uptake, two experiments were conducted in […]
Physiochemical variations in soil and behavioral changes in growth pattern of lentil in response to application of fertilizer factory effluent
Owing to its economic aspect, the trend of using industrial effluent to irrigate agricultural crops is gaining popularity in Pakistan. This study was carried out to gauge the possible effects of fertilizer factory effluent on the chemical properties of soil and growth performance of lentil (lens culinaris) crop. Four different concentrations of fertilizer factory effluent […]
Allelopathic effects of aqueous extracts of different organs of redroot pigweed (Amaranthus retrofelexus L.) on summer savory (Satureja hortensis L.)
In order to demonstrate the allelopathic effects of different organs (root, shoot and whole plant) of redroot pigweed (Amaranthus retrofelexus L.) on germination, emergence, growth and development of summer savory (Satureja hortensis L.) under laboratory and greenhouse conditionan experiment was carried out as CRD design with nine and five replications at laboratory and greenhouse of […]
