The study has been conducted in a professional greenhouse where grafted seedlings and grafted eggplants have been produced. Two eggplant hybrids, 'Classic F1' and 'Black Pear F1' were used as scion and one of the Lycopersicon genus, 'Kaiser F1' and three Solanum genus, 'L1S', 'L23B' and 'Torpedo' were used as rootstocks, resulting in eight grafted combinations. It has been observed that for all grafting combinations the grafting percentage was ranging from 95% to 98%. The rootstocks utilized have influenced the vigour of the grafted plants. They influenced plant height which reached values of roughly 1.0 m and number of leaves resulting in values of 2.5-3.0 times higher in comparison to the ungrafted plants. Comparative to the ungrafted plants the grafting combinations also influenced the productivity of plants. The highest fructification potential has been observed at 'Classic F1' grafted on all eggplant rootstocks. Compared to ungrafted plants, which has yielded 2.46 kg per plant, the highest yield obtained from 'Classic F1' grafted on 'L23B' has been of 4.27 kg per plant, followed by 'Torpedo' rootstock with 4.1 kg per plant. 'Black Pearl F1' have been produced 4.15 kg per plant when grafted on the 'Kaiser F1' rootstock and 4 kg per plant when grafted on the 'Torpedo' rootstock. Regarding the production per hectare, the largest production augmentation, of 30%, was noted at 'Classic F1' grafted on the eggplant rootstock 'L23B'. The 'Black Pearl F1' grafted on the tomato rootstock 'Kaiser F1' registered a 20% increment in production. The rootstocks utilized have slightly influenced the content of the soluble dry substance on both hybrids grafted on 'Kaiser F1'. The result has been a 6% dry substance in comparison to the 5.3% at the ungrafted hybrids. The grafting has had an insignificant influence of the total amount of carbohydrates at all grafting combinations.

The main purpose of the present research was the study of the behaviour of some headed Chinese cabbage varieties in the Transylvanian Tableland late spring specific conditions. The present research took place in the experimental field which belongs to the Vegetable Growing Department from the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, in the spring of 2011. The results showed that Chinese cabbage can be cultivated with success in Transylvanian Tableland specific conditions even in late autumn, even if previous studies have shown that very good results can be obtained in spring and summer, but it is necessary to choose the right variety or hybrid, because of the high bolting tendency of this vegetable.

Cauli lower is grown for its hypertrophied in lorescences that are used in the preparation of various fresh cooked dishes as well as in pickling or canning industry. The in lorescences are rich in water (90%). The energy value of cauli lower in lorescences is low (118.5 kJ / 100) due to low content of energetic substances. Cauli lower culture is practiced in the ield and in protected areas. Climatic conditions are favorable for growing cauli lower in Transylvania. Cultures are mainly started with seedlings leading to additional costs for their production. The experience was carried out in 2011-2012 in the Reghin area, Mures County. Experimental factors were planting date and culture method. Experimental culture was established at different dates (April, May, June) by two methods (by planting seedlings and direct seeding). The aim of the experiment was to demonstrate the feasibility of growing cauli lower crops by direct seeding, in Reghin area, and if the obtained results, are comparable to those achieved by seedling cultures. In the experiment it was found that direct sowing method can be best practiced if the culture is established in June.

Sweet corn (Zea mays L.) belongs to the Gramineae family, var. rugosa (Bonof) convar. Saccharate (Sturt.) and can be distinguished from normal corn by presence of one or more mutant genes that affect carbohydrate metabolism in endosperm. Purpose of this research is to compare behavior of sweet corn hybrids created at SCDA Turda, but also foreign hybrids, in terms of quality elements and chemical composition, in conditions of Transylvania plateau, in two localities: Turda and Viişoara. As biological material following domestic sweet corn hybrids were chosen: ‘Prima’, ‘Estival’, ‘Deliciul verii’, ‘Dulcin’, ‘Delicios’, ‘Estival M’ and foreign hybrid ‘Jubilee’. These hybrids were also analyzed in terms of chemical composition. Weight of ‘Estival’ hybrid has the best behavior in both localities; as regards to cobs length, ‘Delicios’ hybrid has registered increases very significant positive, differences between plant height in the two localities confirm significant influence of environment on formation of this important typical qualitative characteristics, highest performances in terms of β-cryptoxanthin and zeaxanthin content, are recorded by ‘Jubilee’ in both localities, ‘Deliciul Verii’ hybrid records significant value for lutein content, also recording an important addition of carbohydrates in Turda, ‘Prima’ and ‘Estival’ hybrids recorded highest values of sucrose in both localities.
