ABSTRACT

The Romanian eggplant growers get important productions in protected spaces, besides optimum natural periods. The average yields obtained from crops of grafted eggplants are with approx. 25% higher compared with productions of ungrafted culture. The experience was conducted at the Horting Institute Bucharest, Romania. The grafted and ungrafted eggplant plants were obtained and maintained during vegetation period according to the classic technologies, in some specialized greenhouses: a greenhouse specialized in producing of vegetable seedlings, it has a 1450 square meters surface, it is protected against condense by a double layers cover with an under pressure air layer as thermal insulator and it is equipped with a system for shadowing, ventilation and cooling of the grafting room and a greenhouse for vegetable cultures (glass greenhouse of block type). The paper objective was to identify the impact of Romanian rootstocks on short time storage at some Dutch eggplants. The experiences regarding the eggplant storage were organized concerning the maintaining duration of the quality by losses analyzing (weight and impairment) and the main biochemical changes (soluble dry matter, total sugar) during storage. For experimentation, were used eggplants from ungrafted plant culture, composed with the hybrid Black Pearl F1 and eggplants from grafted plant culture composed with some combinations scion x rootstock, Black Pearl F1 x L11, Black Pearl F1 x L23B, Black Pearl F1 x L1S, Black Pearl F1 x L5S. The eggplant storage was made in 3 variants: unpacked, temperature of 23-250C and relative humidity to 40%; unpacked, temperature of 40C and relative humidity of 90%; packed in plastic boxes and temperature of 40C. Best results were obtained at eggplants stored packed in boxes and 40C. The experience was insured statistically. The eggplant quality is affected during prolonged storage.
