Abstract

Research on prolonging vase life of chrysanthemum aimed to recognize some concentration of sucrose andcitric acid applied on solution to prolong vase life of chrysanthemum. Randomized Block Design was applied onthis research with two factors. First factor was concentration of sucrose, consisted of four levels which were 0, 2,4, and 6 percent of sucrose. Second factor was concentration of citric acid, consisted of four levels which were0, 200, 400, and 600 ppm of citric acid. All combination treatments were replicate two times. Variables whichwere observed in this experiment i.e.: vaselife, percentage of full bloom, percentage of flower wilting, and totalof absorbed solution. The results showed that the longest vase life of chrysanthemum cut flower was found onsample treated by 2.70% of sucrose combined with 400 ppm of citric acid. The longest vase life was 13.02 daysor 6.02 days longer than control.

Abstract

Tomato (Lycopersicum esculentum Mill.) is a fruit with many benefits. Plant growth regulators (PGRs) prove effective in improving the quality and production of tomatoes. Gibberellic Acid/GA is a PGR that stimulates the process of flowering, parthenocarpy, and carbohydrate mobilization during germination and influences other plant physiological aspects. However, because synthetic GA is costly, numerous natural ingredients have been proposed as its source, for example, bamboo shoots, vegetable ferns, corns, and shallots that can improve the quality of tomatoes. This study aimed to determine the role of natural GA from various plant extracts on the quality of tomatoes, providing recommendations for the best extract to improve the quality of tomatoes. It was conducted in the experimental garden at the Agronomy and Horticulture Laboratory, Physiology Laboratory of the Faculty of Agriculture, and Food Analysis Laboratory of the Faculty of Agricultural Technology, Udayana University. This research was compiled using a Randomized Group Design consisting of one factor, i.e., the type of natural extract with five settings and four repetitions. The tomato plant treatments were E0 = no extract sprayed, BE = sprayed with bamboo shoot extract, VE = vegetable fern extract, OE = onion extract, and CE = corn extract. The results showed that gibberellins from natural ingredients significantly affected fruit diameter, fruit thickness, and total sugar content of tomatoes. The best tomatoes were obtained by applying onion extract as a source of natural gibberellins.

Abstract

The effect of using various packaging treatments on extend the shelf life of strawberry fruit and their physico-chemical changes Strawberry is one among horticultural commodities that has a significant potential being developed commercially in Bali. Strawberry fruit commonly has a relatively sweet taste and a strikingly bright red color. Strawberry fruit is easily damaged and has a short shelf life, so it is necessary to inhibit the damage, among others by the use of various packaging treatments. This study aims to extend the shelf life of strawberry fruit and the effect of using various packaging treatments on their physico-chemical changes. The experimental design used was completely randomized design with one packing type factor consisting of 3 treatment levels, ie without packaging, use of mica package, and use of styrofoam package.The results showed that strawberry fruits treated with mica and styrofoam pacgages had a longer shelf life than strawberry fruit stored without any packaging (control). The storage period of strawberries both treated with mica and styrofoam packeges were last up to the 4th day. The use of mica package showed the best results with the lowest shrinkage value, lowest softness, low respiration rate and high organoleptic value. Eventhough strawberry fruit packed with styrofoam package showed a high vitamin C content, but the strawberry fruit packed with mica package has a better visual appearance with good fruit quality and mostly accepted by the panelist.
