In vitro regeneration in olive (Olea europaea L.) cv, 'Frontio' from nodal segments.
An efficient and reproducible protocol for plantlet regeneration from nodal segments of Olive cv 'Frontio' has been developed. Media and explants browning due to exudation of phenolics from the explants were controlled by fortification of the medium with 100 mg/L ascorbic acid. Best establishment of olive explants was observed on half-strength MS salts fortified with 2.0 mg/L 6-benzylaminopurin...
متن کاملPhenolic Compounds from Olea europaea L. Possess Antioxidant Activity and Inhibit Carbohydrate Metabolizing Enzymes In Vitro
Phenolic composition and biological activities of fruit extracts from Italian and Algerian Olea europaea L. cultivars were studied. Total phenolic and tannin contents were quantified in the extracts. Moreover 14 different phenolic compounds were identified, and their profiles showed remarkable quantitative differences among analysed extracts. Moreover antioxidant and enzymatic inhibition activi...
متن کاملIdentification and localization of a caleosin in olive (Olea europaea L.) pollen during in vitro germination
In plant organs and tissues, the neutral storage lipids are confined to discrete spherical organelles called oil bodies. Oil bodies from plant seeds contain 0.6-3% proteins, including oleosins, steroleosins, and caleosins. In this study, a caleosin isoform of approximately 30 kDa was identified in the olive pollen grain. The protein was mainly located at the boundaries of the oil bodies in the ...
متن کاملریزازدیادی زیتون .Olea europaea L
در این بررسی جوانه های انتهایی و جانبی (قطعات گره دارای دو جوانه) از پایه های برتر موجود در رویشگاه طبیعی زیتون از جمله طارم، منجیل، رودبار و گرگان و نیز پایه های موجود در موسسه محل تحقیق در فصول مختلف سال برداشت شد و پساز اعمال تیمارهای ضدعفونی کننده با دو عامل کلرور مرکوریک و هیپوکلریت سدیم و نیز تلفیقی از آنها، روی دو محیط کشت پایه MS و OM استقرار یافتند. نمونه های مستقر شده جهت تحریک شاخه ...
متن کاملIn vitro olive (Olea europaea L.) cvs Frantoio and Moraiolo microshoot tolerance to NaCl
In vitro culture of rooted and unrooted olive microshoots, established from seed lines of free-pollinated ‘‘Frantoio’’ and ‘‘Moraiolo’’ cultivars, were evaluated for NaCl tolerance. The aim was to use growth and physiological parameters in order to identify salt-adapted genotypes. Leaf tissue elemental distribution of Na, Cl and K was also investigated in unrooted plantlets by cryo-scanning ele...
