Effects of the Pretreatment and Length of Low-Temperature Storage Period of Runner on Plantlet Growth in the Shoot Apex Culture of Strawberry (Fragaria*ananassa Duchesne).

Tubers from 7 potato varieties were analyzed for their rates of glycoalkaloid accumulation in response to stresses of three types of mechanical injury and low temperature storage. Mechanical injuries were found to greatly stimulate glycoalkaloid accumulation in both peel and flesh of tubers. The extent of glycoalkaloid accumulation appears to depend on variety, type of mechanical injury, and storage period. Most of the injury-stimulated glycoalkaloid accumulation occurred within 7 and 14 days after treatment. Cutting the tubers resulted in the highest content of glycoalkaloids both in flesh and peel up to levels that exceeded the upper safety limit of 200 mg/kg FW. Injury stimulated α-solanine accumulation in stored potato tubers is more than α-chaconine, resulting in a decrease in the α-chaconine: α-solanine ratio. When tubers were stored at low temperature, the rate of glycoalkaloid accumulation was found to be independent of the glycoalkaloid level at harvest. The greatest increase in total glycoalkaloid content of the seven varieties was found after two weeks of storage at both 4 ºC and 10 ºC. Further storage at these temperatures resulted in a decrease in the rate of glycoalkaloid accumulation in most of them. At 10 ºC glycoalkaloid content tended to increase more rapidly than at 4 ºC. The α-solanine content of the tubers showed an increase following low temperature storage.

This research aimed to know the shelf life of mullet fillet with basil leaves extract treatment in different concentration based on the amount of bacteria contained on mullet fillet during low temperature storage. The research was conducted at The Central Laboratory and The Laboratory of Fishery Product Processing, Padjadjaran University, Jatinangor. The method used in this research was experimental with four treatments by duplo. Basil leaves extract treatment concentrations were given in 0%, 1.5%, 3% and 4.5% concentrations, soaked for 30 minutes and stored at low temperature (5-10℃). The observations for grey mullet fillet with 0% concentration (without soaking on basil leaf extract treatment) were made on the 1st, 3td, 5th, 6th, 7th, 8th and 9th day of research. The observations for 1.5%, 3% and 4.5 concentrations were made on the 1st, 3rd, 5th, 6th, 7th, 8th, 9th, 10th, 11th and 12th day of storage period. The parameters observed in this research was the amount of bacteria. The result of research showed that the use of basil leaf extract in concentration of 3% on mullet fillet during low temperature storage has the longest shelf life, that was until 11 days with total amount of bacteria about 4.55 x cfu/g.

This research was conducted in the Laboratory of Fishery Products Processing, Faculty of Fisheries and Marine Science, University of Padjadjaran, Jatinangor. The purpose of this research is to obtain the optimal concentration of chitosan as an antibacterial material wich had the longest of storage period of pangasius fillet at low temperature storage (5-10oC). The method used is an experimental method with a completely randomized design, four treatments and three replications. Pangasius fillet was soaked with chitosan 0%, 1%, 2% and 3% for 3 minutes, then packed with styrofoam and plastic wrap and stored at low teperature. The observation were made on day 1st, 3rd, 5th, 6th ,7th, 9th,10th, 11th and 12th. The parameters observed total bacterial colonies, the degree of acidity (pH), weight loss, and antibacterial activity of chitosan using disc diffusion methods. The final conclusion is that the 2% chitosan is optimal concentration for pangasius fillet storage at a low temperature until day 11th, with a total 6.7 X105 cfu/g of bacterial colonies, pH 6.67 and total 6,78 % of weight loss.Chitosan also has a higher antibacterial capability against Escherichia coli (Gram negative bacteria) than Staphylococcus aureus and Bacillus subtilis (Gram positive bacteria).

Demand for mangosteen fruits (Garciana mangostana L) is currently increasing both for local and export markets. Quality of mangosteen fruit has been kept until now, even increased by efforts of post-harvest handling. The problem on postharvest of mangosteen is mainly on storage process. The quality of mangosteen is affected by the temperature condition during storage period. Waxing is usually used for fruits to extend their shelf life. In this study, combination of waxing and low temperature storage were studied to obtain the optimum storage condition for mangosteen. The objectives of this study were to determine the effect of combination of waxing and low temperature storage on the quality changes of mangosteen. It was shown that storage of mangosteen with waxing treatment of 5% and temperature storage of 8oC resulted the longest period of storage, i.e., 39 days. At this condition, the firmness was 2.00 kgf, total soluble solid was 16.10oBrix, and respiration rate of CO2 was 1.67ml/kg hr. In this study, prediction of storage life of mangosteen was carried out based on the firmness which accepted by panelist from organoleptic test. It is shown that waxing concentration 0% and temperature storage 8oC effectiveness to storage life until 16 days.

The oxygen uptake of flower buds from Van der Cruyssen azaleas was measured while and after plants were treated with 45 days of 2 °C storage or with 7-weekly sprays of 500 p.p.m. gibberellic acid (GA). Respiration of the flower buds decreased during the cold-storage period. In contrast, respiration of the buds from both GA and cold storage treated plants was greater than that of control plants for the 2- to S-week posttreatment period. This increase reached a peak at the 3-week point.
