Together with water and carbon dioxide plants require 14 essential mineral nutrients to finish their life cycle. The research in plant nutrition can be traced back to Julius Sachs, who was the first to experimentally prove the essentiality of mineral nutrients for plants. Among those elements Sachs showed to be essential is sulfur. Plant sulfur nutrition has been not as extensively studied as t...

Rosa hybrida L. is an important commercial cut flower. Salicylic acid (SA) and calcium chloride (CaCl2) act as endogenous signal molecules responsible for growth parameters in plants. The aim of this study was to evaluate the effects of preharvest SA and CaCl2 treatments in extending the vase life of cut rose flowers. Therefore, a factorial experiment based on completely randomized design with ...

in calcareous soils with high calcium carbonate contents and ph, the growth and development of plant might undergo nutritional disorders. the process of biological nitrogen fixation in legumes cultivated and plant growth in these soils could be limite. the use of acid-producing materials like sulfur and a reduction in soil ph improves plant growth and increase the biological nitrogen fixation. ...

Nitrogen (N) is an essential macronutrient and a key structural component of macromolecules in plants. N nutrients and metabolites can act as signals that impact on many aspects of plant biology. The plant life cycle involves a series of developmental phase transitions that must be tightly coordinated to external and internal cues in order to ensure plant survival and reproduction. N availabili...

background: satureja khuzistanica jamzad, with the common persian name “marzeh khuzestani”, is an endemic medicinal plant, distributed in the southwestern areas of iran. salicylic acid (sa) is a signaling molecule and a hormone-like substance that plays an important role in the plant physiological processes. objective: this study was conducted to determine the influence of foliar sa application...

Rapeseed (Brassica napus L. ssp. oleifera Metzg) is attacked by a wide range of pests. Breeding resistant cultivars one the best methods protecting crops against insects, and non-cultivated species Brassicaceae can be used as resistance donors. In this study, we investigated relationship between nutrient content to two commonly occurring pests (Delia radicum Brevicoryne brassicae) in 12 hybrid ...

Soils in many parts of the world are contaminated with heavy metals, leading to multiple, deleterious effects on plants and threats to world food production efficiency. Cadmium (Cd) is one such metal, being toxic at relatively low concentrations as it is readily absorbed and translocated in plants. Sulfur-rich compounds are critical to the impact of Cd toxicity, enabling plants to increase thei...
