. Setyorini, D., D. Indradewa, and E. Sulistyaningsih. 2009. Fruit Quality of Tomato Planted inDifferent Plastic Mulch. Environment conditions is one of important factor that may affect plant growth. Modificationof environment conditions will not only affect plant growth, but also fruit quality. This study was carried out in TheExperimental Garden and Horticultural Laboratory of College of Agriculture, Gadjah Mada University. The experimentwas set up in a randomize block design with 5 levels of treatments (plastic mulch color) and 4 replications. Parameterobserved were fruit number per plant, damaged fruit per plot, fruit weight, diameter and length of fruit, fruit firmness,coefficient of fruit ripening, total soluble solid, vitamin C, and dominant acid. The results showed that the color ofplastic mulch had a specific effect on tomatoes fruit quality parameter. The use of red plastic mulch reduce thepercentage of damage fruits but decreased the coefficient of fruit ripening. The blue plastic mulch had a significanteffect on increase fruit firmnes. Meanwhile, the silvery black plastic mulch could increase the dominant acid contentthat was suitable for growing processing tomatoes
