a factorial experiment based on completely randomized design (crd) was performed with three replications to investigate the interaction between salinity and nh+4 / no-3 ratio on olive saplings. four levels of salinity (0, 50, 100,150 mm) and different ratios of nh+4/ no-3 (0:14, 2:12, 4:10, 6:8) were applied on one-year old olive saplings grown in perlite: sand media (1:1). results indicated th...

Using two lowland rice (Oryza sativa L.) cultivars we found that in both cases submerged-induced elongation early after germination depends on gibberellins (GAs). Submergence increases the content of the active GA 1 by enhancing the expression of GA biosynthesis genes, thus facilitating the seedlings to escape from the water and preventing asphyxiation. However, the two cultivars differ in thei...

olive is a perennial evergreen tree which has good adaptability to poor environmental conditions such as salt and drought resistance. in recent years, there is a tendency to plant olive trees in green spaces. therefore, this study was carried out to evaluate 15 olive cultivars regarding growth habit, form, and texture to recommend for landscape. six-year-old trees of 15 olive cultivars, which h...

A reliable DNA extraction method for use on extra virgin olive oil based on a commercial kit was defined, and the possibility of using this DNA for fingerprinting the original cultivar was demonstrated. The genetic traceability of single-cultivar virgin olive oil from two cultivars (Carolea and Frantoio) was achieved by identifying the varieties from which they were produced. This involved the ...

Various products are used to mitigate the negative effects of abiotic stress in olive trees. The aim research was examine an anti-transpirant product (Vapor Gard®, V) and a kaolin- based (Manisol, K) effect on growth two-year-old tree seedlings under high temperature. study conducted greenhouse trees native cultivar Campania (cv. Salella) grown pot during growing season from May September 2020....

olive (olea europaea l.) consumption and production are socially and economically important in iran. the aim of this experiment was to evaluate the vegetative characteristics, floral biology, fruit characteristics, oil percentage, and yield of eleven olive cvs. (‘arbequina’, ‘amygdalolia’, ‘bledy’, ‘roghani’, ‘zard’, ‘sevillana’, ‘koroneiki’, ‘conservalia’, ‘gordal sevillana’, ‘manzanilla’, and...
