Uptake Of Nutrients

Wheat (Triticum aestivum L) is the most important food grain crop among cereals and stands next only to rice in our country. It is an exhaustive crop which requires the major and micronutrients in adequate amounts for higher production. Wheat is quite responsive to phosphorus (Singh at al. 2020) and manganese (Singh and Patra, 2017) which plays important role in growth and development. Phosphorus is an important nutrient needed for normal growth and development of the plants. It plays an important role in energy transformation and metabolic processes in plants. Manganese plays a role in the synthesis of chlorophyll. Manganese deficiency occurs in well drained light textured soils with neutral or alkaline in reaction. Studies have indicated both synergistic and antagonisticrelationship between P and Mn but their relationship depends on their rate of application and crop species. Hence, an attempt was made to study the response of wheat to P and Mn nutrition in an alluvial soil.

Membrane lipid remodelling is one of the strategies that plants have developed to combat abiotic stress. In this study, physiological, lipidomic and proteome analyses were conducted to investigate the changes in glycerolipid and phospholipid concentrations in the wheat (Triticum aestivum L.) cultivars CIGM90.863 and Seri M82 under hypoxia treatment. The growth of CIGM90.863 remained unaffected, whereas Seri M82 was significantly stunted after 8 days of hypoxia treatment. The concentrations of all lipids except lysophosphatidylglycerol were significantly higher in the leaves of Seri M82 than in CIGM90.863 under normal growth conditions. The lipid profile changed significantly under hypoxia stress and varied between genotypes for some of the lipids. Phosphatidic acids remained unchanged in Seri M82 but they were gradually induced in CIGM90.863 in response to hypoxia stress because of the higher phospholipase D expression and lower expression of diglycerol kinase and phosphatidate phosphatases. In contrast, digalactosyldiacylglycerol content was highly stable in CIGM90.863 following hypoxia treatment, although it decreased significantly in Seri M82. Phosphatidylglycerol and lipoxygenase showed a stronger and faster response in CIGM90.863 than in Seri M82 under hypoxia stress. Different membrane lipid adjustments in wheat under oxygen deficiency conditions could be partly responsible for the differing tolerance of Seri M82 and CIGM90.863. This study will help us to better understand how wheat tolerates hypoxia stress by regulating lipid remodelling.

The growth and development of Wheat (Triticum aestivum Linn.) plant has been studied using self-prepared kitchen waste biofertilizer. The experimental plants which were grown using the biofertilizer prepared using the kitchen biodegradable wastes excelled on all the parameters tested (rate of seed germination, root – shoot ratio, chlorophyll contents in leaves and Nitrate Reductase activity) in comparison to traditional chemical fertilizers and therefore, the prepared biofertilizer has been found to be more effective nutrient supplier than the traditional chemical fertilizers.

A comparative study was made of the growth and development of the shoot apex/inflorescence in two contrasting spring wheat (Triticum aestivum L.) cultivars: Marquis—a standard height, day-length-sensitive type; and Pitic 62—a semidwarf, Norin 10 derivative with relatively low day-length sensitivity. The effects of 8-, 12-, 16-, 20-, and 24-h photoperiods and of two nitrogen levels in 12 and 20 h on both cultivars were determined, as well as those of two phosphorus levels on Marquis in 20 h.Apical primordium production continued for a longer duration in Pitic than in Marquis, and the initiation of spikelet primordia was delayed. Spikelet development was more synchronous in Pitic than in Marquis in all treatments. Apical spikelet formation always coincided in both cultivars with the initiation of rachis internode extension. Inflorescence development after termination of spikelet primordia formation was as fast in Pitic as in Marquis (or faster in short photoperiods).In general, increasing N increased the rate and duration of primordium production (apical spikelet formation occurring later at high N), and delayed inflorescence development and extension. These effects were more pronounced in Pitic, resulting in much greater N responses for spikelet and grain numbers per spike, and for grain yields per spike. Effects of high P were similar to those of high N. Increasing photoperiod increased the rate, but decreased the duration of primordium production, and accelerated the development and the extension growth of the inflorescence.The results are discussed in relation to a postulated involvement of endogenous gibberellins and inhibitors in the regulation of inflorescence growth and development.
