Functional-structural plant modeling (FSPM) is a fast and dynamic method to predict plant growth under varying environmental conditions. Temperature is a primary factor affecting the rate of plant development. In the present study, we used three different temperature treatments (10/14°C, 18/22°C, and 26/30°C) to test the effect of temperature on growth and development of rapeseed (Brassica napu...

the species of dioscorea (yam) are regarded as a staple food crop for millions of people in the tropical and subtropical regions of the world. it is regarded as an important food crop next to cereals and grains due to high yield storage of carbohydrates. economically, only few species are recognized for cultivation from agricultural point of view, in spite of its large species diversity. the sp...

Ethiopia is the center of origin for Ethiopian mustard (Brassica carinata). The crop one oldest oil crops and farmers in highlands country grow as a leafy vegetable their gardens. However, no attempt has been made to assess association characters path analysis leaf. This study was conducted traits among yield related determine direct indirect effects traits. A total 36 genotypes were evaluated ...

forty-nine preserved specimens (31 male and 18 female) of trachylepis aurata transcaucsasica were examined with respect to metric and meristic features and dry skull anatomy to assess sexual dimorphism. thirty-one morphological characters and 36 anatomical characters in dry skulls were examined. subdigital lamellae under the forth toe, neck length, neck length/snout vent length, and six skull c...

salinity stress is one of the most important abiotic stresses which threaten plants. in order to study the effect of salinity stress on yield and yield components of sunflower and also genetic analysis of these traits in relation with salt tolerance, a factorial experiment based on a completely randomized design with three replications was conducted. pots were arranged outside the greenhouse in...

to conserve the genetic resources and identify the strong and weak points in sistan watermelon accessions and compare these with improved cultivars of: sugarbaby and fairfax, an experiment was carried out, based on rectangular lattic design of two replications in 2007. the morphological traits studied, included plant length, plant weight, seed weight, fruit number, fruit length, fruit width, su...

The attitude of policymakers and designers of green space is increasing toward to native-ornamental species to plant in the urban space because of their adaptation and resistance against severe weather and ecological conditions which can result in cost minimization and long-term survival in green spaces. Hence, the current study was carried out in the west of Mazandaran Province on three wild a...

ABSTRACT: Leaf area of dried Flue-cured tobacco is a reflection climate and stage growth fresh in field; it also serves as the foundation for calculating number significant physical properties tobacco. So purpose this paper was to establish model estimate leaf China from linear dimensions. Three Hundred eight leaves different growing stalk position were sampled randomly separated selection amon...

ABSTRACT The leaf area is a parameter of fundamental importance in studies on plant growth and physiology. objective this study was to build allometric equations for the accurate fast estimation sapodilla areas. In total, 250 leaves different shapes sizes were collected from matrices trees growing at Universidade Federal Rural do Semi-Árido, Mossoró-RN, Brazil. For each leaf, length, width, pro...
