“…4a, the glucose content of M 2 was higher than the control (P \ 0.05), while glucose content of M 1 was lower, and there was no significant difference between them. The change in glucose was similar earlier report (Frazier et al 2006). Compared to M 0 , fructose content of M 2 was declined significantly (P \ 0.05), and M 1 was lower than M 0 (P \ 0.05) (Fig.…”

The aim of this study was to investigate the role of ethylene to control sprouting of potatoes by observing the effect of exogenous ethylene on carbohydrate metabolism and key enzymes. The initial time of potato tuber sprouting and sprouting index were recorded, and rate of respiration, total sugar, total reducing sugar, starch, fructose, glucose, sucrose and the activities of acid invertase (AI), neutral invertase (NI), sucrose synthase (SS), sucrose phosphate synthase (SPS), starch phosphorylase and amylase during sprouting were measured. Exogenous ethylene inhibited sprouting of potato tubers. Moreover, exogenous ethylene increased respiration total sugar, AI activity, SPS activity, SS activity, and reduced sugar and assay activity. Nevertheless, starch, glucose, fructose, NI activity and starch phosphorylase activity showed lower variation. Lower sprouting resulted into potatoes with higher levels of total sugar, total reducing sugar and glucose, and lower level of fructose and sucrose. And sprouting could be inhibited by increasing the activities of SS, SPS and AI by treatment with 199.3 ll L -1 exogenous ethylene. Overall, exogenous ethylene inhibited sprouting of potato tubers by influencing its carbohydrate metabolism.

“…The critical problem, however, is to find the optimum radiation level that can fulfill the preservation requirements without causing serious chemical alteration of the food, which would affect its organic acceptability and wholesomeness, Farkas (1985). As Frazier et al (2006) showed successful sprout suppression was achieved with doses of 40-50 Gy while higher doses caused undesirable increase in reducing sugars in the tubers. On the other hand Umeda et al (1969) showed that higher storage temperature required higher dose of radiation.…”

The effects of gamma radiation treatment (50 and 100 Gy) on potato tubers irradiated at different days (10th, 30th and 50th) after harvest were studied during 5 months of storage at 10°C using Agria and Marfona varieties. A factorial experiment was done, based on a Randomized Complete Block Design with four replications. The 100 Gy radiation treatments on 10th and 30th days after harvest completely prevented sprouting at both varieties studied but on 50th day only Agria tubers not sprouted. This study indicated that early irradiation and absorbed radiation doses significantly decreased sprouting, percent weight loss and specific gravity of tubers. Reducing sugar content significantly increased by delay in irradiation and lower dose of radiation while non-reducing sugars did not decrease significantly by delay in irradiation and higher dose of radiation. The least increase in reducing sugars (10.2%) and most decrease in non-reducing sugar (-12.75%) were observed in tubers that irradiated on 10th day after harvest. The content of ascorbic acid was decreased by irradiation with higher dose. Although delay in irradiation caused less loss of ascorbic acid (8.5%) but showed greater metabolic changes as sprouting, weight loss, firmness, and sugars contents. Also, more increased delay in irradiation needed higher radiation doses for sprout inhibition.

“…Since bud tissues in eyes are meristematic and are least tolerant to gamma irradiation, their blackening occurs at 500 Gy [46]. Tuber lots with high rot potential may not be suitable for gamma irradiation treatment at all [43].…”

“…Apparently, sugar molecules are a product of starch glycoside bonds breakage by gamma-rays [54]. Frazier et al [43] demonstrated that a dramatic raise in sugar content occurs after irradiation at 20 ... 40 Gy and storage at +7.2 °С; then the sugar content is normalized to the untreated control level in 210 days if stored at +7.2 °С or in a month if stored at +15 °С. The content of reducing sugars in tubers exposed to 1 kGy was 1.3 fold lower than at 80 Gy when stored at +22 °С for 120 days [50]; glucose content in tubers at 2 kGy was 1.8 fold higher than at 150 Gy when stored at +24 °С for 35 days.…”

Potato is an important staple food crop. Potato tubers require proper treatment before planting and after harvest to produce high yields and avoid storage losses. Among different techniques of potato treatment physical methods are of special interest: thermal treatment using hot water and steam, ultraviolet (including continuous-wave UV using pulsed Xe-lamps) and gamma-irradiation, treatment with magnetic and electromagnetic fields (including microwaves). The majority of physical methods is environmentally friendly and can be applied without special registration and in the developing countries. In the present paper, for the first time, the scientific papers on physical methods of potato treatment for the last 35 years are comprehensively reviewed. The review demonstrates that such an approach is perspective both for pre-planting and postharvest treatment of potato. Physical treatment affects biochemical, cellular and physiological status of potato. Methods of physical treatment enable to control phytopathogens, and some methods (ultraviolet and gamma-radiation) even are capable of improving immunity of plants. The main traits of potato tubers that can be influenced by physical treatment are sprouting (stimulation or inhibition), susceptibility to rot and black leg diseases, and starch, reducing sugars and ascorbic acid contents. The tuber response to physical treatment depends on dosage and date of treatment, duration and temperature of storage, agricultural technology and cultivar. Low doses of treatment may be inefficient while too high dosage may result in cell deterioration or death and poor immunity, and eventually to disease development. Too early treatment may damage a tuber since it should pass through suberization (wound healing) after harvest; too late treatment requires higher doses. The proper adjustment of treatment is necessary for cultivar and individual storage conditions.
