during summer. In order to obtain some decorative plants its absolutelynecessary to pay special attention to the vegetal material used for breeding:seeds, logs, and also of the method characteristic to the cultivation of suchplants.Moreover, plants culture state of health must represent a majorconcern, because diseases and pests attack may lead to the considerabledepreciation of the plants quality.Research have been performed within Floriculture subject in 2011 at theDidactic Basis of Banat University of Agricultural Science and VeterinaryMedicine, and had as main analysis object 3 genera (hybrids) of zonalPelargonium flowers.sublayers,height,inflorescence , CycoganComparative studies on some late ripening pear hybridsDoltu Madalina 1 , Alexe Constanta 1* , Lamureanu Gh 2 ., Sora D. 21 Research and Development Institute for Processing and Marketing of the Horticultural Products Bucharest;2 Research Station for Fruit Growing Constanta;*Corresponding author. Email: tantialexe@yahoo.comAbstract The breading of the pear cultivars is a basic activity in fruitgrowingresearch taking into account the great importance of this specie innourishment, but witch has only 4,3% from the total fruit production in ourcountry. Taking into account the necessity of the perpetual renewal andimprovement of the pear cultivars, both for consumers and farmers, weproposed to study three late pear hybrids (H4-15/18, H5-12/15, H6-9/12)from the point of view of the trees vigour, their phonology, production capacityand fruit quality. The researches took place between 2006-2008, in a pearorchard set up in 1999, with trees of one year old, planted at 4/2 m distance(1250 trees/ha). The pear trees were grafted on the quince tree rootstock,with a small vigour of growing. Observations were made regarding thepermanent structure of the late pear hybrids, the ramified and formation cropcapacity, the phonology of floral organs, binding capacity of fruit, productiveefficiency, the relationship between the leaf‟ surface and growing level of thesprouts, fruit quality. The obtained results show the high productive potentialof late pear hybrids studied, grown in Bucharest area, an zone which assuresthe development of physiological and biochemical process at a sustainedlevel, giving a strong long life and a corresponding vegetation state to thisspecies. From the three hybrids, a remarkable evolution has the hybrid H6-9/12, with a superior potential above the other two.Key wordsbiological potential,phonology, productivecapacity, fruit quality
