Sorting sugarbeets by specific gravity to obtain more uniform samples for post-harvest studies

An experiment was done to assess the effect of various post -harvest treatments of ethrel on ripening behaviour and post -harvest quality of mango cv. Amrapali (Mangiferaindica L.) during storage at Punjab Agricultural University, Regional Research Station, Gurdaspur during the years 2013-14 and 2014-15. The experiment was planned under completely randomized design (CRD) with three replications. The treatment units was six fruits per replication. Total five treatments and control were applied. The objective of this work was to evaluate the effects of various concentrations of ethrel (500 ppm, 750 ppm, 1000 ppm,1250 ppm, 1500 ppm and control ) on shelf life of mango fruits when stored under ambient conditions. The treated fruits were assessed for physiological changes fruit colour, flavour/aroma, organoleptic taste, marketability, ripening, specific gravity, moisture loss, decay, physiological loss in weight (PLW), total soluble solids (TSS), acidity and sugars. The observations were recorded at 5, 8 and 11 days after storage. At 11th day of storage these mangoes exhibited deep yellow fruit colour with excellent flavour, organoleptic taste and highly acceptable marketability at 1000 ppm ethrel treatment as compared to other ethrel doses. Fruit ripening (100%), specific gravity (0.84), TSS(23°Brix) and sugars(20.65%) were highest in the fruits treated with 1000ppm ethrel as compared to rest of treatments at 11th day of storage. Lowest moisture loss (8.5%), decay (1%), PLW(12.50%) and acidity(0.12%) were observed in the fruits treated with 1000ppm of ethrel as compared to rest of treatments at 11th day of storage. The beneficial effect of the present study is to overcome the problem of uneven and late ripening of Amrapali mango by postharvest treatment of ethrel at 1000 ppm at their mature green stage to develop typical fruit flavour with excellent fruit quality.

Post Harvest

The highland of Bale is known with potato production, but post harvest quality of the crop is not emphasized yet. Therefore, this study was conducted to evaluate six potato varieties with the objective of assessing the effect of varieties and growing on tuber nutritional and process quality of potato grown in Sinana and Dinsho highlands of Bale. The experiment was laid out in randomized complete block design with three replications. The varieties showed highly significant (P<0.05) differences for all the parameters studied across the locations. The highest specific gravity, dry matter content and starch content (1.107, 26.61 and 19.19) were recorded from Dinsho location for Guddene variety while the lowest specific gravity, dry matter content and starch content (1.084, 19.41 and 14.61) were recorded from Sinana location for Ararsa variety. Most of the varieties were recorded as the highest values of specific gravity, dry matter and starch content at Dinsho indicating that it is an ideal location for potato production to be used for processing while Sinana is suitable for the production for home consumption. However, it is necessary to evaluate these varieties for a number of seasons and locations to recommend with high post harvest quality parameters required by the processors.Int. J. Agril. Res.

The bulk loss function Im(-l/ε (ω)), a well established tool for the interpretation of valence loss spectra, is being progressively adapted to the wide variety of inhomogeneous samples of interest to the electron microscopist. Proportionality between n, the local valence electron density, and ε-1 (Sellmeyer's equation) has sometimes been assumed but may not be valid even in homogeneous samples. Figs. 1 and 2 show the experimentally measured bulk loss functions for three pure silicates of different specific gravity ρ - quartz (ρ = 2.66), coesite (ρ = 2.93) and a zeolite (ρ = 1.79). Clearly, despite the substantial differences in density, the shift of the prominent loss peak is very small and far less than that predicted by scaling e for quartz with Sellmeyer's equation or even the somewhat smaller shift given by the Clausius-Mossotti (CM) relation which assumes proportionality between n (or ρ in this case) and (ε - 1)/(ε + 2). Both theories overestimate the rise in the peak height for coesite and underestimate the increase at high energies.
