A comparative review of the elementary chemical composition of aquatic vascular plants is presented together with the author’s own results. Attention
In the biosphere plants are exposed to different forms of N, which comprise mineral and organic N forms in soils as well as gaseous NH3, NOx, and molecular
Multiphasic Uptake in Plants II. Mineral Cations, Chloride, and Boric AcidUptake of alkali cations, metal ions, chloride, and boric acid is shown by reanalysis of available data to be mediated by single, multiphasic mechanisms which may be fundamentally similar in a variety of plants and tissues...
The nutrient ions taken into the cell are transported through the protoplasmic connection (symplastic transport). As a result of these processes, plants can selectively and positively take in a specific ion. The nutrients move upward with water through the xylem to reach the whole plant body. ...
Nutrient uptake by two cultivars of tomato plants The nutrient consumption by two tomato plant cultivars (Vemone and Marglobe) was calculated from measurements of the concentration of individual ions in th... O Carpena,A Masaguer,MJ Sarro - 《Plant & Soil》 被引量: 17发表: 1988年 Amino ...
Plants were grown at different nitrate concentrations (0.8 and 4 mM), with mineral composition of growth and uptake solutions identical. Nitrate influx, efflux and net nitrate uptake rate (NNUR) were independent of the external nitrate concentration, despite differences in internal nitrate ...
Zinc (Zn) is an essential micronutrient with numerous cellular functions in plants, and its deficiency represents one of the most serious problems in human nutrition worldwide. Zn deficiency causes a decrease in plant growth and yield. On the other hand,
Strong interactions were observed between photoperiod and root-zone temperature on the concentration of numerous mineral elements in maize tops and roots. Someone proposed that photoperiod could affect the concentration of some plant-growth regulators. These plant-growth regulators could change the nutrient...
Copper (Cu) is an essential mineral nutrient for the proper growth and development of plants; it is involved in myriad morphological, physiological, and biochemical processes. Copper acts as a cofactor in various enzymes and performs essential roles in photosynthesis, respiration and the electron tran...
In addition, the study demonstrated that the exogenous supply of nitrates helps compensate for nitrogen deficiency caused by lead action and supports the mineral balance. The reduction in lead toxicity to plants after foliar application of nitrates may be due to the stimulation of the biosynthesis ...
