Polyethylene Bags

Winter dug strawberry runners of the cultivar Red Gauntlet were stored in sealed or ventilated polyethylene bags at -2.2�C for 63 months. After storage and before planting, runners received post storage treatments at 256�C. Crown and root growth occurred where treatment duration at 25.6�C exceeded two days. This did not adversely affect vigour in the field after planting, but did reduce fruit yield in the autumn crop. Pre-storage benomyl dusting reduced mould infection after cool storage and before planting. Crown and root growth and weight loss was reduced where runners were contained in sealed polyethylene bags, and significantly higher fruit yield was subsequently obtained from these treatments.

Secondary Effect

Treatment of topped radishes (Raphanus sativus L., cv. Cherry Belle) with methyl jasmonate was effective in inhibiting postharvest sprouting of new leaves and the growth of roots. Radishes were trimmed to 10-mm tops and dipped in various methyl jasmonate suspensions for 3 min. After storage at 15 °C for 7 days, the growths of new leaves were 26, 22, 7, 3, and 1 mm in 0, 10–5, 10–4, 10–3, or 2 × 10–3 M methyl jasmonate-treated radishes, respectively. The lengths of root growth were also reduced by methyl jasmonate particularly at higher concentrations. These treatments also substantially reduced weight loss possibly as a secondary effect. Fumigation with methyl jasmonate vapor in enclosed containers was also effective in inhibiting the sprouting of leaves and root growth, but to a lesser extent than dipping treatments. Radishes stored at 0 °C did not show any new growth of leaves or roots, and therefore were not affected by the methyl jasmonate treatments.

Important Disease

Botrytis blight caused by Botrytis cinerea is an important disease of rose (Rosa hybrida) grown in greenhouses in Brazil. As little is known regarding the disease epidemiology under greenhouse conditions, pathogen survival in crop debris and as sclerotia was evaluated. Polyethylene bags with petals, leaves, or stem sections artificially infected with B. cinerea were mixed with crop debris in rose beds, in a commercial plastic greenhouse. High percentage of plant parts with sporulation was detected until 60 days, then sporulation decreased on petals after 120 days, and sharply decreased on stems or leaves after 90 days. Sporulation on petals continued for 360 days, but was not observed on stems after 150 days or leaves after 240 days. Although the fungus survived longer on petals, stems and leaves are also important inoculum sources because high amounts of both are deposited on beds during cultivation. Survival of sclerotia produced on PDA was also quantified. Sclerotia germination was greater than 75% in the initial 210 days and 50% until 360 days. Sclerotia weight gradually declined but they remained viable for 360 days. Sclerotia were produced on the buried petals, mainly after 90 days of burial, but not on leaves or stems. Germination of these sclerotia gradually decreased after 120 days, but lasted until 360 days. Higher weight loss and lower viability were observed on sclerotia produced on petals than on sclerotia produced in vitro

Storage Disorders

Wax coatings containing diphenylamine (DPA) reduced weight loss from apples and pears in storage, kept the fruit firmer and greener, improved its external appearance and significantly reduced rates of respiration and ethylene production. In addition they reduced the incidence of superficial scald and other storage disorders. The preferred wax concentration for practical application to apples was 8 per cent total solids (ca. 6 per cent wax) as higher concentrations tended to produce off-flavours, particularly during holding at 20�C after cool storage. Waxing of pears prevented normal ripening at 20�C, and so cannot be recommended as a storage aid for this fruit.

Effective Treatments

A number of treatments known to affect low temperature breakdown of apples or low temperature injury of peaches were applied to Starking Delicious peaches. Within each treatment, low temperature injury increased as the weight loss of the fruit increased, but there were also differences between treatments that were not due to differences in weight loss. Warming during storage, stepwise cooling, and delayed storage were the most effective treatments in reducing low temperature injury.

Peaches (Prunus persica) were evaluated for storability after dipping in a 2% calcium chloride (CaCl2) solution at 20 °C for 30 min and storing them at 4 °C for 2 weeks in boxes uncovered or covered with polyethylene bags. Generally, there were significant improvements in storability resulting from the CaCl2 and the polyethylene barrier. The CaCl2 treatment improved firmness, largely maintained the soluble solids content, and increased the ratio of soluble solids-to-titratable acid ratio. Polyethylene bags minimized weight loss, and two out of three times, bagged fruit had lower acids after storage than did the control.

A field experiment was conducted during 2006-07 and 2007-08 at Precision Farming Development Centre, Horticulture Farm, Indira Gandhi Agricultural University, Raipur, Chhattisgarh, India to evaluate the weed dynamics, yield, quality, organoleptic parameters and root growth of Capsicum as influenced by drip irrigation and mulches. The black polythene mulch being at par with paddy straw mulch gave the least weed population, dry weight and highest weed control efficiency over other mulches. Drip irrigation at 0.6 Epan obtained the least value of weed growth and highest weed control efficiency. Drip irrigation at 1.0 Epan showed highest fruit yield (32.02 t ha-1), total soluble solid (5.72), ascorbic acid (120.25 mg 100g-1) and organoleptic parameters but root growth registered maximum in flood irrigation at 1.0 IW/CPE. Black polythene followed by paddy straw mulch showed maximum fruit yield and other parameters. Pungent test scored maximum with flood irrigation at 1.0 IW/CPE and no mulch. Drip irrigation at 1.0 Epan along with black polythene as well as paddy straw mulch restrict weed growth, harvested quality fruit with higher fruit yield of capsicum.

In the spring of 2001 and 2002, different combinations of media (coarse perlite, medium perlite, and pine bark) and containers (polyethylene bags and plastic pots) were used for hydroponic production of `Galia' muskmelons (Cucumis melo L.) to determine their effect on fruit yield and quality, and their influence on costs of production. Marketable yields obtained for `Gal-152' in the spring 2001 and 2002 were 25.5 kg·m–2 and 39.0 kg·m–2 respectively. When data were combined for 2001 and 2002, fruit yield and fruit quality were unaffected by any combination of media and container. Average soluble solids content was generally greater than 10° Brix. It was determined that the use of pine bark media and plastic pots instead of perlite and bags would save $18,200 per year (two crops)—a feasible option for reducing costs of producing `Galia' muskmelons in greenhouses using soilless culture without loss of yield and fruit quality.

Cool Storage

The incidence of breakdown in Jonathan and Delicious apples stored in the presence of calcium chloride was studied. Jonathans from two orchards and Delicious from one orchard were stored at 32�F in 1963, and Jonathan and Delicious from one orchard were stored at 30�, 32�, and 36�F in 1964. On four occasions in 1963, and on three in 1964, samples were transferred from cool storage to storage at 68�F and inspected for breakdown seven days later. In each of the thirty orchard-variety-season-storage period classes the decrease in incidence of breakdown with increased weight loss was always very highly significant (P<0.001), and varied from 2.1 to 8.7 degrees for each per cent of weight loss.

The storage of sweet potato tuberous roots in tropical countries is a major challenge to farmers and retailers due to unfavourable climatic conditions. In this study, the storage performance of sweet potato roots in an ambient condition was investigated over a 12-week duration. The three different pre-storage treatments used were ash, alkaline solution (1.5 mol dm-3) and Siam weed (Chromolaena odorata) extract – to evaluate their effects on weight loss, shrinkage, weevil damage and sprouting. The control comprised tubers with no pre-treatment. It was observed that weight loss increased linearly from the inception of storage while shrinkage became apparent only after two (2) weeks. The percentage shrinkage of the tuber pre-treated with Siam weed increased at decreasing rate from 8 WAP. Treatment of tuber with Siam weed extract provided significantly higher protection against weevil damage (p > 0.05). After this, sprouting was initiated. By the 12th week, the Siam weed (Chromolaena odorata) extract treatment yielded better results. The Siam weed (Chromolaena odorata) treatment also recorded the lowest weight loss of 28% and lowest shrinkage of 2.8%. It also sustained less weevil damage at 33.5% compared with the other treatments. Sprouting was higher in the tuber without pre-storage treatment. The alkaline solution and ash treatments had varied degree of performance for all the indicators. Keywords: Sweet potato storability, Ambient condition, Pre-storage treatment, Chromolaena odorata
