STUDIES REGARDING THE INFLUENCE OF IRRIGATION ON FRUIT YIELD AT APPLE TREES IN IARA - TURDA, TRANSYLVANIA CONDITIONS

The paper presents the results of the experiments that were carried out during 2012-2014 period, in the Iara-Turda depressionary area conditions. The research`s general objective is the study of agroproductivity at Jonagold, Florina, Generos, Idared, Jonathan, Granny Smith and Golden Delicious apple varieties, all grafted on to a semi-vigourous M106 rootstock. The influence of the irrigation and fertilization regime was studied in an polifactorial experiment that aimed the study of the interactions of three factors and the specific and cumulative effects on growth and fructification parameters of the apple tree varieties in the pedoclimatic context of the studied area. The present paper refers only to the interaction and effect of the irrigation regime in relation to the studied factors

THE INFLUENCE OF GENOTYPE, TREATMENT AND STORAGE PERIOD ON AGEING PROCESS OF HYBRID CORN SEEDS

The ageing process of corn seeds is an important economical and quality factor in corn growing, therefore the study of the impact of factors that influence the quality of the seeds during the storage period as well as their interaction has to be carried out in order to improve the process of storing seeds. Different types of methods can limit the ageing process and expand the storing period, such as treatments applied to seeds in order to reduce the fungal, bacterial and other infestations as well as monitorig and creating a constant environment in the storage facilities, but a great influence in the storage capacity of corn seeds is due to the bilogical material, the corn hybrids
