Effect of 'Gutingen V' as an intensive training system on agromorphological characters of some apple cultivars in Karaj region of Iran

V-shape systems represent an efficient and popular option to increase yields and fruit quality in fruit trees. Hence, this paper attempts to compare some vegetative and yield characteristics of five apple cultivars grown at horticultural research station in Karaj, Iran. The selected apple cultivars were included: 'Golab-kohans' (Iranian cultivar), 'Fuji', 'Gala', 'Starking' and 'Delbar estival' (commercial foreign cultivars) that were grafted on M.9 rootstock which were trained in a V system. All of these trees were planted in winter 2005. The time of irrigation started from the second experimental year after planting and the method of irrigation was drip irrigation system. Results showed that the 'Golab-kohans' had the most tree height (278.63 cm), trunk cross sectional area (7.308 cm2) and mean shoot length (100.58 cm). Also 'Delbar estival' had the most yield (0.98 kg), yield efficiency (0.550 kg/cm2). Consistently, Results revealed that among the investigated cultivars, 'Delbar estival' can be introduced as a prone and productive cultivar for V system in Karaj's climatic conditions

Drought Responses in Six Hazelnut (Corylus avellana L.) Cultivars

[EN] Drought is one of the major causes of reduction of crop yields worldwide, a problem that will increase in the next decades due to climate change. We describe here an initial attempt to define biochemical markers associated to water stress in several hazelnut cultivars, by measuring the levels of common osmolytes and the generation of secondary oxidative stress, in plants subjected to water stress, and after recovery from the stress treatment. Proline (Pro) appears to be a reliable marker in this species, as its accumulation in leaves correlates well with the degree of stress affecting the plants. Differences between cultivars in relative Pro accumulation and oxidative stress suggested that some cultivars are more tolerant than others and could be selected for cultivation in drought-affected areas.Shahi-Gharahlar, A.; Fatahi, MR.; Zamani, Z.; Al Hassan, M.; Boscaiu Neagu, MT.; Vicente Meana, Ó.
