Hydroponic Screening of Rice Genotypes for Salinity Tolerance at Seedling Stage| Chapter 3 | Research Highlights in Agricultural Sciences Vol. 8

 The present aims to judge the physiological action of eight rice genotypes resistance to salt stress at seedling stage under hydroponic method. Salinity is a major abiotic determinant that affects edible grain cultivation in the globe along the coastal districts. The salt touched areas in India is supposed to be about 8 to 10 million hectares that causes significant decline in rice progress and yield. In order to improve the edible grain cultivars for salt fortitude, selection of the suitable genotypes is made necessary. The Hydroponics experiment was conducted at Glass apartment, Department of crop physiology, Tamil Nadu land university, Coimbatore.  Study was transported to screen eight rice genotypes (CO 51, ADT 53, ADT 37, IR 64, CO 43, ASD 16, Pokkali; TRY 3) for salinity fortitude at early seedling stage. Results from this study emanated that that seedling limits were reduced under salty conditions, Na+ ion Concentration and Na+/ k+ percentage was higher in salty treatments compared to control. However, K+ ion incorporation decreased accompanying increasing salinity level. Electrolyte outflow and osmotic potential had increasing style with increasing salinity. The edible grain genotypes Pokkali, TRY 3, CO 43 were performed as open-minded; CO 51, ADT 53, ASD 16 were performed as slightly tolerant; ADT 37 was acted as susceptible and IR 64 was performed as well susceptible. Salt persuaded osmotic stress leads to physiological dryness, causes many disorders and injuries in plant. Ion aggregation also causes change in osmotic potential of plant; for fear that such osmotic imbalance and confine the entry of sodium and chloride ions into plants. To found genotypes that are tolerant to seasoning stress during the large plant enclosed in bark and shedding leaves stage and to increase rice growth and yield in consideration of meet national necessities, this kind of research should.

Aquaponics: A Way of Green Technology| Chapter 9 | Cutting Edge Research in Biology Vol. 1

 Green electronics (GT) is a broad term and a field of new innovative habits to make environmentally-companionable changes in daily history. It is created and used in a habit that conserves natural resources and the atmosphere. Aquaponics is the combination of two together agricultural practices, growing plants in liquid and hydroponics. In aquaponics, water from the growing plants in liquid is supplied to the raising animals system. At the same time, the by-products are shabby by nitrifying bacteria, making the outgrowth to be exploited as nutrients by plants. The growing plants in liquid system following receives the water by recirculation. If fishes are working in an aquaponics system, the fishes are given their fare, the fishes work to feed the plants, and the plants clean the water for the fishes. Aquaponics has many advantages like allure sustainable, exhaustive food result system, needs 1/6th water to evolve eight times more cooking per acre, and soil is not required, so no soil-carried diseases, fertilizers or synthetic pesticides not required, Aquaponics maybe used on non-farmable lands such as chastisement, degraded soil or pungent, sandy islands, builds little waste and provides occupation. Some disadvantages further exist, aforementioned that start-up costs, demand expertise, day-to-day management needed, and extricate feed and electric supply add ornament to the input costs. Considering the benefits and disadvantages of aquaponics, it is individual of the best patterns available in green electronics, and it will help in the conservation of natural resources.

Investigating the Effect of Lead on Marsilea minuta Linn. Under Hydroponic Conditions| Chapter 12 | New Perspectives in Agriculture and Crop Science Vol. 3

 

The degree of the concentration of lead (Pb) that induces toxicity in the pteridophytes of lower vascular plants remains unknown. The present study was therefore intended to investigate the degree of Pb accumulation in Marsilea minuta Linn, with its effect on the physiological and biochemical basis of heavy metal tolerance. Mining and smelting operations, Pb2+ containing paints, fuel and explosives, as well as the disposal of urban sewage sludge enriched in Pb and emissions from motor vehicles & industrial plants are the product of lead contamination. Plants were permitted to absorb lead salt at lower concentrations (0 μM, 0.1 μM, 0.3 μM, 0.5 μM and 1.0 μM) during hydroponic culture for 12 days, and significant degradation of plant biomass was recorded. T T However more metals than leaves were consumed by the roots. Changes in leaf area, allocation of biomass, leaf chlorophyll content, total carbohydrate content and protein content have been monitored. Higher concentrations of up to 1.0 μM decreased the quality of biomass and chlorophyll. In the early days of treatment, a significant decrease in total protein content was observed, accompanied by a sharp rise in treatment of 0.3 μM, 0.5 μM and 1.0 μM. The overall carbohydrate content was reduced by 1.0 μM and increased by 0.5 μM compared to control conditions.
