Few teleost fishes incubate embryos out of water, but the oxygen-rich terrestrial environment could provide advantages for early growth and development. We tested the hypothesis that embryonic oxygen uptake is limited in aquatic environments relative to air using the self-fertilizing amphibious mangrove rivulus, Kryptolebias marmoratus, which typically inhabits hypoxic, water-filled crab burrow...

background and objectives: availability and uptake of mineral by explants are recognized as being important in tissue culture. the limiting factor for maximum mineral uptake and optimum growth is that minerals are not enough available to the explants. there are the inter-relationships between plant growth, mineral uptake, medium water potential, and mineral movement through the medium. plantlet...

Ammonium sulfate, ammonium carbonate or ammonia gas inhibited water uptake in sugar beet roots whenever the pH was sufficiently high to cause the production of ammonia. When ammonia was removed by aeration, inhibition of the water uptake by roots was rapidly reversed. ATP at 0.2 mm appeared to either wholly or partially prevent the ammonia-induced inhibition of water uptake by roots. ATP may be...

Vegetative buffer strips are vegetated areas (usually strips) between fields and waterbodies that can mitigate the effects of agricultural activities by acting as a physical barrier to sediment and nutrients being carried to streams, and thereby have been widely used as a best management practice (BMP). Buffers can slow surface water flow and allow greater water infiltration, trapping the sedim...

succinate, while ?Ig+, AMP, and DPN+ were required for the oxidation of citrate. 2. Pyruvate-2-C14 and acetate-2-C14 were metabolized by the mitochondria. 3. The absorption of water by the endosperm tissue was accompanied by the activation of the Krebs cycle enzyme system. 4. The capacity of mitochondrial particles to oxidize succinate decreased as the embryos germinated; their ability to oxidi...

cadmium is a heavy metal with a strong adverse effect on crop quality. moreover, it is a mobile element in environment and plants can easily uptake and transfer it to their organs. cadmium can easily enter human and animals food chains and threatens their health. to study the effects of a water soluble polymer and inoculation with mycorrhizal fungi on cadmium uptake of clover grown on contamina...

In this study, we investigated the effects of balanced deep-sea water (BDSW) on hyperglycemia and glucose intolerance in high-fat diet (HFD)-induced diabetic C57BL/6J mice. BDSW was prepared by mixing deep-sea water (DSW) mineral extracts and desalinated water to give a final hardness of 500-2000. Mice given an HFD with BDSW showed lowered fasting plasma glucose levels compared to HFD-fed mice....

Water, salinity and nitrogen are the major factors affecting maize production in arid and semi-arid areas. The objectives of this study were to investigate the effects of different water, salinity and nitrogen levels on yield-water relationships, water use, water productivity (WP), water use efficiency (WUE) and water uptake reduction function by maize hybrid SC-704 in a semi-arid area and ...

Water deficits severely affect growth, particularly for the plants in arid and semiarid regions of the world. In addition to precipitation, other subsidiary water, such as dew, fog, clouds and small rain showers, may also be absorbed by leaves in a process known as foliar water uptake. With the severe scarcity of water in desert regions, this process is increasingly becoming a necessity. Studie...
