Exogenous brassinolide (BR) application is a feasible measure to alleviate abiotic stresses on crop productivity. The effects of BR at the silking-stage accumulation, translocation, and remobilization dry matter (DM) nutrients (nitrogen, phosphorus, potassium) waxy maize exposed post-silking high temperature (HT) were studied using Jingkenuo2000 (JKN2000, heat-tolerant) Yunuo7 (YN7, heat-sensit...

A paradox is commonly observed in productive sea ice which an accumulation the macro-nutrients nitrate and phosphate coincides with of autotrophic biomass. This requires a new conceptual understanding biogeochemical processes operating ice. In this study, we investigate using three time series Antarctic landfast ice, massive algal blooms are reported (with particulate organic carbon concentrati...

Macrophytes plays important role in balancing Lake Ecosystem. They have capacity to improve the water quality by absorbing nutrients, with their effective root system. At the same time death & decay of the macrophytes increases nutrient concentration, this leads to eutrophication. A rational setup between these two simultaneous activities is required to maintain the water quality of an aquatic ...

Green manure intercropping is an agronomic management practice that effectively increases soil nutrients in understory and reduces weed population. However, the influence of different green manures on properties bacterial community litchi orchards tropical regions China remains largely unknown. Here, we examined effect three leguminous crops Hainan Province. No was used as control. Different in...

The effect of meat peptone type I (Sigma) on the growth of Escherichia coli cells under hyperosmotic stress has been investigated. Peptone is a complex mixture of peptides with a small content of free amino acids, which resembles nutrients found in natural environments. Our data showed that peptone enhances the growth of E. coli cells in high-osmolarity medium to levels higher than those achiev...

When plants encounter nutrient-limiting conditions in the soil, the root architecture is redesigned to generate numerous lateral roots (LRs) that increase the surface area of roots, promoting efficient uptake of these deficient nutrients. Of the many essential nutrients, reduced availability of inorganic phosphate has a major impact on plant growth because of the requirement of inorganic phosph...

Grazing livestock create localized nutrient patches that increase soil ionic strength (IS) and influence plant productivity. The ability of plant root systems to control ion absorption and flux to xylem, and to sequester ions reaching leaf tissue in bound, nontoxic forms are means of minimizing IS. A greenhouse experiment was conducted to determine the growth and mineral acquisition responses o...
