Tillering (branching) is a major yield component and, therefore, a target for improving the yield of crops. However, tillering is regulated by complex interactions of endogenous and environmental signals, and the knowledge required to achieve optimal tiller number through genetic and agronomic means is still lacking. Regulatory mechanisms may be revealed through physiological and molecular char...
We aim to incorporate deep root traits into future wheat varieties to increase access to stored soil water during grain development, which is twice as valuable for yield as water captured at younger stages. Most root phenotyping efforts have been indirect studies in the laboratory, at young plant stages, or using indirect shoot measures. Here, soil coring to 2 m depth was used across three fiel...
Silicon (Si) has beneficial effects on the growth, yield, and tolerance of some crops against biotic and abiotic stresses. Considering the absence of Si in the nutrient solutions used in hydroponically-grown cucumber, the present study was conducted to investigate the influence of Si on the growth and yield of two cucumber genotypes (Cucumis sativus L. cvs. Dominus GRC and Super Dominus). In a ...
In arid and semi-arid areas of the world, excessive mineral aerosol carried by air parcels is a common climatic incident with well-known environmental side effects. In this study, the role of sand-dust accumulation was investigated on various aspects of photosynthetic yield of Plantago lanceolata including chlorophyll (Chl) a, b, effective quantum yield of PSII photosystem (ФPSII), maximal quan...
Pusa Basmati 1121 (PB1121), an elite Basmati rice cultivar is vulnerable to salinity at seedling stage. A study was undertaken to impart seedling-stage salt tolerance into PB1121 by transferring a quantitative trait locus (QTL), Saltol, using FL478 as donor, through marker assisted backcrossing. Sequence tagged microsatellite site (STMS) marker RM 3412, tightly linked to Saltol was used for for...
This study was conducted to evaluate the effect of sulfur on morphological traits of promising L17 line of canola at Mazandaran Agricultural and Natural Resources Research and Education Center-Baye Kola Research Station based on randomized complete block design with three replications in 1397-1398. In this research, the different traits such as plant height, number of pods in main shoot, total ...
to study the effect of sowing date and supplemental irrigation on grain yield and distribution and remobilization of phosphorus in canola (brassica napus), this experiment was carried out in 2 years (2005-07) in research station of gonbad. the study was carried out in two types of irrigation treatments (rainfed, supplemental). both experiments were carried out in randomized complete block desig...
Potato is a strategic crop in Tunisia but is susceptible to many pests and diseases. Nematodes of the genera Meloidogyne and Globodera are important pests that cause yield losses and depreciation of tuber quality. A trial was carried out in a plot where the soil was naturally infested with M. javanica and G. pallida. Three soil treatments were tested and compared. Soil solarization (SS) and inc...
