The pot experiments were conducted in the Department of Life Science and Bioinformatics of Assam University, Silchar. The aim of the present study was to investigate the effect of dual inoculation of Arbuscular mycorrhiza (AM) (Glomus fasciculatum) and Rhizobium on the chlorophyll, nitrogen and phosphorus contents of pigeon pea (Cajanus cajan L.). The results revealed an overall increase in chl...

Chlorophyll content, the most important pigment related to photosynthesis, is the key parameter for vegetation growth. The continuous spectrum characteristics of ground objects can be captured through hyperspectral remotely sensed data. In this study, based on the coniferous forest radiative transfer model, chlorophyll contents were inverted by use of hyperspectral CHRIS data in the coniferous ...

A field and laboratory based experiment conducted to assess the effects of different pH ranges of simulated acid rain (2.5, 3.5, 4.5 and 5.5) was studied on chlorophyll and ascorbic acid contents in two cultivars (cv. Himalaya and cv.Kaushik) of a medicinal herb Mentha piperita. Chlorophyll and ascorbic acid contents of leaves were adversely affected at pH 2.5 and 3.5. The effects of simulated ...

UV-B radiation induced alterations in the contents of photosynthetic pigments, antioxidants (phenolics and ascorbic acid) and chlorophyll fluorescence in two tropical variants of Trichosanthes cucumerina L. – Cucurbitaceae. The Green (Variant A) and Light Green (Variant B) variants of T. cucumerina, which had earlier been shown to differ in their total phenolics contents, were used for the stud...

For over 100 years it has been known that iron is essential for the growth of higher plants and that it is involved in some manner with chlorophyll metabolism. Jljin (17, 18, 19) demonstrated that iron deficiency in plants resulted in decreased dry weight, salt, and protein nitrogen contents and increased contents of amino and organic acids. Extensive studies (8, 9, 25, 33) have confirmled Ilj ...

Leaf and canopy nitrogen (N) status relates strongly to leaf and canopy chlorophyll (Chl) content. Remote sensing is a tool that has the potential to assess N content at leaf, plant, field, regional and global scales. In this study, remote sensing techniques were applied to estimate N and Chl contents of irrigated maize (Zea mays L.) fertilized at five N rates. Leaf N and Chl contents were dete...

cold stress is considered as a restricting factor in plant production. recently, many different compounds were applied to minimize the harmful effects of stress. in this study, the effects of foliar application of salicylic acid was studied on some biochemical properties of two different cold resistant canola cultivars. salicylic acid was sprayed at four concentrations (0, 100, 200 and 400 µm) ...

Few studies have investigated the alkali-based salt resistance aspect of plants. Here, we used 2 pumpkin cultivars (‘Cucurbita ficifolia Bouch.’ and ‘Chuandilong’) to study the growth and physiological response mechanisms of pumpkin to different levels of NaHCO3 stress. After second true leaf development, pumpkin seedlings were treated with varying levels of NaHCO3 stress (0, 30, 60 and 90 mmol...

iron deficiency in soil reduces the quality of durum wheat leading to fe deficiency in human. thus, this experiment investigated the effects of foliar application of nano-iron oxide (2 and 4 g l-1), iron chelate (edta), (4 and 8 g l-1), iron sulfate (4 and 8 g l-1), and the control on grain yield and quality, yield components, chlorophyll and carotenoids contents, peroxidase (pox), catalase (ca...
