“…We consider area measurements from plant images as a proxy for biomass measurements as these traits have been shown to be correlated for a number of plant species, including sorghum (Fahlgren et al, 2015; Neilson et al, 2015). Additionally, the effect of low nitrogen on plant color is well established and RGB image-based methods have been described to estimate chlorophyll content of leaves (Hu et al, 2010; Shibghatallah et al, 2013; Wang et al, 2014; Cendrero-Mateo et al, 2016; Junker and Ensminger, 2016; Mishra et al, 2016). In contrast to shape, PCA of color (hue and intensity) attributes at the end of the experiment only separated the high nitrogen treatment group away from the two lower nitrogen treatment groups (Figure 2B).…”

“…The variation of leaf colour, photosynthetic activity in most of the plants dependent on chlorophyll concentration. (Shibghatallah, 2013) Chlorophyll content determines the photosynthetic capacity of the plant per unit area of leaf, stress and nutritional deficiencies. (Vimala and Poonghuzhali, 2015) Secondary metabolites are synthesized by the plants as part of the defence system of the plant (Indira et al, 2015).…”

Different species of Cassia found in Jharkhand are consumed as daily vegetables have high nutritional value. Most of them are underutilized and display varied ethenomedicinal values. The work was carried out with an aim to document three ethno medicinal properties of three different species of Cassia, Cassia fistula, Cassia siamea and Cassia tora. The documentation was done among 100 tribal people residing in the area near Morabadi, Ranchi. The knowledge revealed that the three plants were used in almost every tribal houses as a dietary supplement and various medicinal uses. According to the Munda Vaidya’s the plant Cassia is of pitta nature and its different part have different uses. The root is used against tuberculosis glands, diabetes, as a tonic, the root and bark paste mixed in equal amount is used against snake bite. traditionally it is used as laxative, for the treatment of leprosy and various skin disorders. the present study aimed to screen and quantify primary and secondary metabolite by quantitative and qualitative method. The pigments (chlorophyll and carotenoid) were characterised by UV visible spectroscopy. Concentration of chlorophyll-a, chlorophyll-b and carotenoid was calculated by Arnon method (80% acetone extract). The spectrophotometric study of the different pigment of the three species of Cassia, Cassia fistula (chl-a 254.516, chl-b 305.741, total chl 533.7 carotenoid 10.6), Cassia siamea (chl-a 257.88, chl-b 393.16, total chl 630.2 carotenoid 9.395), Cassia tora (chl-a 266.36, chl-b 271.96, total chl 538.32 carotenoid 16.3). The result revealed that chl-a was highest in Cassia tora followed by Cassia siamea and Cassia fistula. Chl-b pigment followed C. siamea> C. fistula>C. tora pattern, total chl C. siemea>C. tora>C. fistula and the carotenoid amount C. tora > C. fistula > C. siamea. In screening of secondary metabolites tannin, saponins alkaloids, terpenoids, resin Phyto-sterols were carried out on the aqueous extract showed +ve test for all except phyto-sterols and on the powdered specimen gave –ve result in aqueous, ethanol as well as acetone extract.

“…Grains configurations are recorder using computer scanner, office equipment which are not so common in use for educational or research purposes. Scanner has been used for simulating roots [8], automatic counting of chemically etched tracks [9], recording color of leaves related to chlorophyll content [10], or as office equipment supporting education process [11][12].…”

-Grains configuration snapshots of Brazil-nut effect (BNE) in two-dimension are physically modeled using disk-formed objects, e.g., buttons and magnetic pin. These BNE configurations are artificially designed to mimic the real ones observed in experiments. A computer scanner is used to capture the configurations. Obtained images are then digitized using web browser running an HTML equipped with a JavaScript code, which is built mainly only for this work. From digitization process all grains positions (granular bed and intruder) are obtained, which is later analyzed using the simplest model, i.e., potential energy. Since the minimum energy principle (MEP) suggests that a closed system should go to its state with minimum internal energy, our BNE system must also obey it. Evolution of only the intruder seems to violate MEP but not for the whole system. Grains compaction plays an important role, so that the system can achieve its configuration with minimum potential energy.Index Terms -Brazil-nut effect, computerscanner, JavaScript, principle of minimum energy.
