Silicon Nutrition and Arbuscular Mycorrhizal Fungi

Neera Garg Purnima Bhandari Lakita Kashyap Sandeep Singh

Abiotic stresses, like salinity and heavy metal toxicity, pose a serious threat to plant growth and productivity. Agricultural soils become unsuitable for cultivation, owing to deleterious effects of these stresses on soil fertility. In recent years, supplementation of soils with silicon (Si) as a nutrient has been shown to exhibit beneficial effects on plants' health, especially under stressed conditions. The protective roles of Si could be due to precipitation of toxic ions with silica, formation of mechanical barrier through deposition of amorphous Si in the subcuticular layer of leaf, maintenance of leaf structures, and light receptiveness so as to increase photosynthetic efficiency of the plants. In addition to this, Si has also been reported to protect plants either by sequestration of toxic ions or by increasing the protein activity to counteract salt and heavy metals' mediated toxic effects. Plant species vary in their capacity to accumulate Si in their tissues, with monocots having higher tendency to take up Si than dicots. Among dicots, legumes are considered moderate to low accumulators and therefore unable to get Si-induced benefits. Arbuscular mycorrhizal fungi (AMF) have also been recognized as a safe, cost-effective, and environment-friendly approach in alleviating these stresses in crop plants. The mechanisms employed by AMF to enhance stress tolerance include reduced toxic ion uptake, increased root rhizosphere, nutrient uptake, and upregulation of plant metabolic processes. Interestingly, AMF have been reported to acquire Si in their spores and hyphae. Therefore, recent studies have been directed toward use of AMF as an external agent to enhance Si uptake and the resultant stress tolerance in crop plants. This article deals with the relative roles of AMF and Si in mitigating salinity and heavy metal stresses and the impact of their dual applications in stress management in crop plants.

Standardization of the Corn silk (Zea mays Linn.)

Research Journal of Pharmacognosy and Phytochemistry (2012)

Hayat M. Mukhtar Sandeep Singh Harjas Kaur Manwinder Singh

Corn silk is collection of the stigmas of corn (Zea Mays). Zea Mays is a monotypic genus of short or tall, generally robust, monoecious, annual grasses belonging to family Poaceae. The plant is reported to possess antifungal, antiviral, diuretic, and antitumour activity. The plant material was collected from Punjab and authenticated by taxonomist of GNDU, Amritsar. In present study, various standardization parameters of corn silk like macroscopical, microscopical characters, physicochemical parameters like total ash (6.5%), water soluble ash (3.6%), acid insoluble ash (1.65%), sulphated ash (1%), foreign organic matter, loss on drying (9.8%), swelling index (2.5%), foaming index (less than 100), successive extractive values in various solvents like petroleum ether (2.1%), benzene (2.4%), chloroform (2.9%), ethyl acetate (3.4%), methanol (28.5%). Cold Maceration values, petroleum ether (2%), benzene (2.3%), chloroform (2%), ethyl acetate (3%), methanol (30%). Behaviour on treatment with different chemical reagents of the dried corn silk, fluorescence characters under visible and ultralviolet light at 254 nm and 366 nm were studied to fix some pharmacognostic parameters that vary from region to region. Preliminary phytochemical studies on different extracts were also reported.

MODULATION OF ANTIOXIDANT ENZYMES SYSTEM BY KINETIN IN SALT STRESSED SHOOTS OF ZEA MAYS

International Research Journal of Pharmacy (2017)

Govinda Asha Sharma Sandeep Singh Jyoti Jyoti

The antioxidant enzymes system in the shoot of the Zea mays was checked in the laboratory.The seeds Soil culture of Zea mays (cv.African Tall-09) were purchased from the local market and sterilized properly.The growth was done for five days and treated by two NaCl (100mM and 200mM) levels, two kinetin (2µM and 5µM) levels and their respective combinations.The enzymatic assays of key antioxidant enzymes i.e. catalase, guaiacol peroxidase (GPX), ascorbate peroxidase, superoxide dismutase and glutathione reductase (GR) in maize leaves were done.The assessment of important metabolic parameters i.e. lipid peroxidation, non-protein thiol levels and proline content in maize leaves was also performed.The activity of catalase was very strongly responsive for kinetin and increased its activity at both the levels.The activity of GR was also inhibited in case of salt and kinetin grouping of lower concentration level.The GPX activity was inhibited by 100 and 200mM of NaCl levels in external medium but stimulated by 5µM Kinetin level alone as well as in high amount salt combination levels while superoxide dismutase of Zea mays shoots was stimulated and showed noteworthy gain were shown in response to 200mM NaCl level as well as kinetin levels.The lower combina tion of both salt and kinetin suppressed the activity of ascorbate peroxidise while the lipid peroxidation and proline content were increased by both the salt treatments.

Effect of integrated nutrient management on indian mustard and soil fertility

Annals of Agricultural Research (2013)

Sandeep Singh Vinay Singh Bandana Singh Chandel

A field experiment was conducted during rabi season of 2008-09 and 2009-10 at Bichpuri (Agra) to study the effect of integrated nutrient management on productivity, quality and uptake of nutrient by Indian mustard and soil fertility. Application of 75% NPK and 5 t FYM ha-1 produced significantly higher seed (2.09 t ha-1) and stover (6.00 t ha-1) yield over either only 100% inorganic fertilizer (4%) or FYM (50%). On an average, seed and stover yields of Indian mustard increased by 37.4 and 45.8, 62.8 and 70.6 and 74.0 and 83.5 % with application of 50, 75 and 100% over control, respectively. Application of FYM (5 t ha-1) alone enhanced the seed and stover yield by 20.6 and 24.1 % over control. The maximum protein (429.3 kg ha-1) and oil (869.0 kg ha-1) yields were also recorded with 75% NPK + 5 t FYM ha-1. The highest uptake of N, P, K and S was also associated with the conjunctive use of 75% NPK and FYM treatment. The maximum values of available N (175 kg ha-1), P (12.0 kg ha-1) and K (155.0 kg ha-1) were noted under 100% NPK alone. On the other hand, maximum value of availableS (17.1 kg ha-1) was noted with 75% NPK + 5 t FYM ha-1.
