“…Such a lot selection will help in effective understanding of the beneficial effects of hydropriming on seed quality attributes of pea seeds. This was reported in another study conducted by the author 10 . To attain the required seed lots for the experiment, initially two lots of pea seed (cv.…”

“…D p = 0.694 ln(M C ) + 6.624 (R 2 = 0.973). (10) The absorption of moisture by seeds while being subjected to accelerated ageing is the possible reason for this positive relation. Similar increase in axial dimensions of seeds as a result of moisture uptake was reported for different granular agro-materials such as rapeseed 22 , dried pomegranate seeds 23 , paddy rice 24 , guar seeds 25 and kenaf seeds 26 .…”

The present study was carried out to determine the physical as well as physiological properties of three fresh pea seed lots (cv. Arkel) with moisture content and germination percentage varying from 14.94% to 28.04% dry basis and 80% to 60% respectively. This variation in moisture content and physiological parameters was obtained using accelerated aging (40C and 100% RH). The geometric (spatial dimensions, sphericity and surface area), gravimetric (terminal velocity, true density, test weight, bulk density and porosity), frictional (angle of repose, coefficient of static friction), mechanical (compressive strength) and physiological parameters (seedling dry weight, seedling length, vigour indices, electrical conductivity and root growth parameters) were determined for the selected seed lots. The effect of moisture content on seed lots was significant (R 2  0.947) on physical and physiological properties of seed lots. This study may help in designing seed priming prototype suitable for pea seeds.

“…Also, the p-values were used as a tool to check the significance of each of the coefficients, which in turn indicate the pattern of interactions between the variables. The insignificant terms from full second order polynomial equation were excluded to get the best-fitted simple predictive equation (Mahawar et al, 2016, Bibwe et al, 2017. pH: The predicted model indicated (Table 2) that the linear effect of dragon fruit juice (P<0.01), grape juice (P<0.05) and quadratic effect of sugar syrup (P<0.1) were the determining factors for pH of the RTS.…”

Abstract:Dragon fruit based ready to serve drink (RTS) was formulated using dragon fruit (60-80% v/v), grape juice (0-10% v/v) and sugar syrup (2-6% v/v). The juice concentrations were optimized using response surface methodology (RSM) following box-behnken design (BBD) for obtaining blended RTS drink with higher functional and nutritional characteristics like total soluble solid (TSS), titratable acidity, ascorbic acid content, total phenol content, colour and sensory evaluation. Results showed that there was significant (P<0.01) effect of incorporating grape juice and sugar syrup which further improved the organoleptic properties of the blended RTS.Optimum juice percentages obtained for the best blend formulation were,dragon fruit (70%), grape juice (5%) and sugar syrup (3%), respectively. The beverage was observed to be acceptable in terms of its nutritional value and overall acceptability.

“…1) also depicted that seeds with higher initial germination tend to absorb less moisture during hydropriming, while the increase in SD and temperature increases the moisture of exposed seeds. It might be due to the fact that seed lots exposed to longer duration of accelerated ageing tend to increase the permeability of seed's cellular membrane and thereby allowing for more moisture absorption while undergoing priming [19]. The inherent moisture content of the seed has substantial effect on its hardness [5], and hence, the seeds subjected to longer duration of hydropriming tend to become softer.…”

“…Hydropriming, as proposed by Harris [11], is a low-cost method with advantageous effects for wheat [9], maize [2] and pea [19]. Factors such as crop species, water potential, priming method, priming duration, temperature, air flow rate and light will determine the success of priming in any crop [29].…”

This research study was envisaged to evaluate the effect of parameters, viz. initial germination percentage (IGP), soaking duration (SD), temperature, rotation speed (rpm) and air flow rate (AFR) for hydropriming of Okra (Abelmoschus esculentus L.) seeds. Three different seed lots based on their moisture content and germination percentage were chosen in this study. Moisture content and germination percentage of the selected lots varied from 11.33 to 16.89% (d.b.) and 50 to 80%, respectively. Accelerated ageing was performed at 40 ± 1°C, 100% relative humidity to obtain required lots from available seed sample. Response surface methodology was adopted using a five factor three-level Box-Behnken design with soaking duration (4, 5 and 6 h), temperature (20, 25, 30°C), rotation speed, (320, 340, 360 rpm), air flow rate, (2.192, 2.740, 3.288 m 3 /min) as the main process parameters. The effect of process affecting parameters was observed on responses, viz. moisture content, germination percentage, seedling length, seedling dry weight, vigour index-I, vigour index-II, electrical conductivity and radiography. Models were found to be significant for all the process responses with the optimal solution as 73% (IGP), 6 h (SD), 23°C temperature, 330 (rpm) and 2.50 m 3 /min (AFR).
