Experimental results concerning the effect of photoperiod andcallus culture duration on anthocyanin synthesisLazăr A. 1* , Petolescu Cerasela 11 Banat‟s University of Agricultural Sciences and Veterinary Medicine Timisoara, Faculty of Horticulture andForestry*Corresponding author. Email: alexlazar2002@yahoo.comAbstract Light has a stimulating effect on callus biosynthetic potential, thegenotype is the main factor that controls the productive potential of cultures.In photoperiod conditions, the highest biosynthetic potential have beenobserved for calli of Negru Tinctorial (12,04 mg/g) and Burgund Mare (5,88mg/g) varieties, while the lowest for calli rising from Cabernet Sauvignon (1,14mg/g), Pinot Noir (2,76 mg/g) and Merlot (3,17 mg/g) varieties.Key wordscallus culture, cell biomass,anthocyanin, Vitis vinifera L.Impact of biostimulators and of rooting substratum on saplinggrowth in Ficus carica L.Poşta Daniela Sabina 1*1 Banat‟s University of Agricultural Sciences and Veterinary Medicine from Timisoara, Faculty of Horticultureand Forestry*Corresponding author. Email: posta.daniela@gmail.comAbstract The biological material is represented by saplings of Ficuscarica L. obtained vegetatively through cuttings using lignified cuts.The rooting substratum used in the experiment was made up withwell-washed river sand.The rooting biostimulators we used were: a solution of Atonik,1:4,000, i.e. 0.25 ml solution per 1 l of water, and Radistim 2 powder.We made morphological feature biometric measurements in eachsapling: sapling height, diameter of the collar, diameter of root system,number of roots, and root lengthKey wordsFicus carica L., cuttings,biostimulators, rootingsubstrate nutrient
