Enhancing Mango Productivity through Sustainable Resource Management

Mango the “King of fruits” is the most important fruit crop in India and the area under mango is the largest among fruit crops (2,516 thousand ha) with a production of around 19.69 million tonnes. India ranks first in mango production in the world contributing 41% of the total world production of mango. Among Indian states, with a total output of 4.3 million MT, Uttar Pradesh stands first as mango producing state. (Fig.1).This is followed by Telangana (2.73 million MT), Karnataka (1.75 million MT) and Bihar (1.36 million MT). Particularly in India all stages of mango fruit are used starting from immature to over ripe stages. Mango has specific problem of alternate bearing leading many times to low yields or no yield

Nucleic acid distribution pattern as a possible biomarker for metabolic activities of neoplastic cells: a digitally-aided fluorescence microscopy study on normal and neoplastic lymphocytes of acute and chronic canine lymphocytic leukemia

<p>Abstract</p> <p>Background</p> <p>Metabolic states of neoplastic cells are increasingly being relied upon for diagnostic and prognostic assessment of neoplastic conditions. The nucleic acid distribution pattern of cells in general, in terms of degree of condensation of the nuclear chromatin and overall spread of the nucleic acid within the nuclear and cytoplasmic compartments, can reflect the metabolic state of the cell. This simple but logical concept appears not be put into consideration to date as numerous attempts are being made towards formulating reliable biomarkers for rapid diagnosis, prognosis and subsequent therapeutic interventions for neoplastic conditions. We comparatively evaluated nucleic acid distribution patterns of normal lymphocytes and neoplastic cells of lymphocytic lineage, employing light and fluorescence microscopy procedures, as well as digital imaging analytical methods.</p> <p>Results</p> <p>The results demonstrate distinctiveness in the pattern of nucleic acid distribution for the normal lymphocytes and three lymphocytic neoplastic cell-types of canine lymphocytic leukemia that are categorized as small, intermediate and large neoplastic lymphocytes. Variably-shaped cytoplasmic processes laden with single-stranded nucleic acids (SSNA) were observed for the small and intermediate-sized neoplastic lymphocytes, compared with large neoplastic lymphocytes and the normal lymphocytes; the latter two categories of cells being virtually devoid of similar processes. Prominent cytoplasmic and nuclear clumps of SSNA, indicative of a higher rate of metabolic activity, were also observed within the neoplastic cells compared with fewer and narrower SSNA of the normal cells.</p> <p>Conclusion</p> <p>The comparative relative increases of SSNA in cytoplasmic processes and other cellular areas of small and intermediate-sized neoplastic lymphocytes is reflective of greater metabolic activity in neoplastic cells in general compared with their normal cellular counterparts.</p

Effect of Planting Density on Growth Parameters and Fruit Yield in Guava (Psidium guajava L.) cv. Allahabad Safeda Cultivated under Mild Humid Conditions of Coorg

A study was carried out in 'Allahabad Safeda' guava (Psidium guajava L.) to standardize the effect of planting densities on growth parameters viz., scion girth, plant height, and spread (East - West and North - South), canopy area, canopy volume and fruit yield over a ten years period. The trial was laid out with five planting densities viz., 6x3, 6x4, 6x6, 8x4, 8x3m accommodating 555, 416, 277, 312 and 416 plants/ha respectively with four replications having sixteen plants per treatment in a randomized block design during 1988-89 season. The grafted plants on seedling rootstock were planted and the yield data were recorded from 1992 to 1997. The results indicated that the scion girth was significantly higher in 8x3 or 8x4m configurations. There were no significant differences among treatments for plant height. The plant spread across East-West direction was however significant in 8x3m. The fruit yield in Mrig bahar was significantly higher as compared to that of Hasth bahar in terms of fruit number and weight. Land Use Index (LUI) values exceeding 50% had bearing on the productivity of different configurations. The productivity was nearly double in 6x3m where, the planting density was twice as much in recommended spacing (6x6m) by sixth year of planting after which, yield levels declined. Thus, it was concluded that a spacing of 6x3m having 555 plants/ha, gives the highest productivity in 'Allahabad Safeda' guava by sixth year of planting under North Coorg conditions

Factors Governing Pasting Properties of Waxy Wheat Flours

Cereal Chemistry, 92(5), 529-535. doi:10.1094/cchem-10-14-0209-rWaxy wheat (Triticum aestivum L.) contains endosperm starch lacking in amylose. To realize the full potential of waxy wheat, the pasting properties of hard waxy wheat flours as well as factors governing the pasting properties were investigated and compared with normal and partial waxy wheat flours. Starches isolated from six hard waxy wheat flours had similar pasting properties, yet their corresponding flours had very different pasting properties. The differences in pasting properties were narrowed after endogenous alpha-amylase activity in waxy wheat flours was inhibited by silver nitrate. Upon treatment with protease, the extent of protein digestibility influenced the viscosity profile in waxy wheat flours. Waxy wheat starch granules swelled extensively when heated in water and exhibited a high peak viscosity, but they fragmented at high temperatures, resulting in more rapid breakdown in viscosity. The extensively swelled and fragmented waxy wheat starch granules were more susceptible to a-amylase degradation than normal wheat starch. A combination of endogenous a-amylase activity and protein matrix contributed to a large variation in pasting properties of waxy wheat flours

N-(5-Bromo­pyridin-2-yl)acetamide

The asymmetric unit of the title compound, C7H7BrN2O, contains two mol­ecules, in one of which the methyl H atoms are disorderd over two orientations in a 0.57 (3):0.43 (3) ratio. The dihedral angles between the pyridine rings and the acetamide groups are 7.27 (11) and 8.46 (11)°. In the crystal, mol­ecules are linked by N—H⋯O and C—H⋯O hydrogen bonds generating bifurcated R 2 1(5) ring motifs, which in turn lead to [110] chains

(2E)-2-(4-Fluoro­benzyl­idene)hydrazinecarboxamide

In the title compound, C8H8FN3O, the semicarbazide group is close to being planar, with a maximum deviation of 0.020 (1) Å, and subtends a dihedral angle of 16.63 (9)° with its attached fluoro­benzene ring.

The trifluoro­methyl group is disordered over two orientations with a refined occupancy ratio of 0.549 (16):0.451 (16). The morpholine ring adopts a chair conformation. The benzene ring and mean plane of the morpholine ring make a dihedral angle of 58.04 (10)° with each other. In the crystal, mol­ecules are connected by inter­molecular C—H⋯F and C—H⋯O inter­actions to form R 2 2(8) ring motifs.

EFFECTS OF SUPPLEMENTATION OF MARIGOLD (TAGETES ERECTA) OLEORESIN ON GROWTH, SURVIVAL AND PIGMENTATION OF ROSY BARB, PUNTIUS CONCHONIUS (HAMILTON)

The study was carried out for a period of 45 days to elucidate the effect of marigold oleoresin on growth, survival and pigmentation of rosy barb, Puntius conchonius. Fish with initial weights ranging from 0.44 g to 0.47 g were fed with test diets T0, T1, T2 and T3 supplemented with marigold oleoresin at levels 0, 60, 120 and 180 ppm respectively. At the end of the feeding trial the total carotenoid concentration in fish muscle found significantly higher (p &lt; 0.05) in both male (3.92±0.01 μgg-1) and female (3.35±0.02 μgg-1) fishes fed diet incorporated with 120 ppm marigold oleoresin. Survival rate of fish significantly increased (p &lt; 0.05) with the supplementation of marigold oleoresin in the diet, highest being in 120 ppm level (96.66±3.33 %). However, there was no significant effect observed in growth, feed conversion ratio and specific growth rate of the fishes. Carotenoid content analysis from whole fish revealed that incorporation of dietary carotenoid resulted in a significant increase in total carotenoid concentration. The study concluded that cheaper and natural colour enhancer diets for rosy barb can be prepared using marigold oleoresin at 120 ppm level
