The effects of varying irrigation intervals (I) and foliar application of salicylic acid (M) on morphological and physiological traits of Catharanthus roseus L. were studied in a factorial experiment based on a randomized complete block design with three replications. The experimental treatments consisted of four irrigation intervals [2 days (I1), 4 days (I2), 6 d...

BACKGROUND Global phosphorus (P) reserves are being depleted, with half-depletion predicted to occur between 2040 and 2060. Most of the P applied in fertilizers may be sorbed by soil, and not be available for plants lacking specific adaptations. On the severely P-impoverished soils of south-western Australia and the Cape region in South Africa, non-mycorrhizal species exhibit highly effective a...

Iron (Fe) is an essential micronutrient for plants, as a cofactor in multi-heme cytochromes and within iron-sulfur clusters. However, Fe can be toxic at high concentrations. Free cells disrupt the cell redox balance toward pro-oxidant state, generating oxidative stress. The focuses of this review were to elucidate detoxification strategies used by well describe excess effects on plant body its ...

Many physiological traits consist of two hierarchically related levels: physical structures and the emergent functional properties of those structures. Because selection tends to act on the emergent functional traits, the evolution of structural phenotypes will depend on the nature of the form-function relationship. Complex physiological or biomechanical traits are often characterized by many-t...

introduction lentil (lens culinaris medik.) is a good source of protein, carbohydrates as well as minerals, vitamins and unsaturated fatty acids as such it plays an important role in the human diet and cultivated worldwide. water shortage is one of the most important abiotic factors that can limit morphological, physiological, yield, and plant distribution. legumes such as lentil are highly sen...

sowing date is the most important factor in physiological and morphological characteristics with positive effects on plants. to evaluate the effect of sowing date and weed interference on yield and yield components of red beans cultivars a factorial split plot experiment in randomized complete block design with three replications was carried out in the research field of zanjan university. main ...
