In grafted seedling production, in addition to the compatibility and performance of rootstock, correct selection grafting method treatments rootstocks nd scion are effective on success graft. A three-stage trial was conducted determine appropriate method, effect root cutting, some cucumber (Cucumis sativus L.). Experiment I, it aimed most technique for by using single cotyledon, hole insertion,...

Pelargonium quercetorum Agnew grows naturally in the Hakkari province of Türkiye. Although P. has potential use as a medicine and ornamental plant, it is especially used medicinal plant for cure various diseases by local people. In vitro tissue culture methods are favorable propagation, conservation, breeding plants. We aimed this study to achieve regeneration from different explant types. Seed...

BACKGROUND Interleukins (IL) play an important role in angiogenesis. Tocopherol possesses immunomodulating effect in addition to antioxidant property. The objective of this study was to determine whether gamma tocopherol's (gT) angiogenic activity in placental network is enhanced via promoting interleukins. METHODS Pregnant ewes (N=18) were supplemented, orally, with 500 mg of alpha tocophero...

The effect of pre and post-anthesis shading (20% of incident radiation) on pericarp development, cotyledon cell number and seed growth dynamic of fruits from three positions in the capitulum (peripheral, mid and central) of two sunflower (Helianthus annuus L.) genotypes were studied at two locations. Both shading treatments reduced pericarp weight, fruit volume and total yield per plant. Plants...

Phototropic and gravitropic curvature by hypocotyls of Arabidopsis thaliana is minimal when the side of the hook with the cotyledons attached is positioned toward the direction of tropistic curvature, and maximal when that side of the hook is positioned away from the direction of tropistic curvature. Based on these data, it is proposed that the position of the hook with attached cotyledons aff...

Organogenesis and neoformant plantlet production were studied by culturing the different parts of mature embryo including radicle and proximal and distal parts of cotyledon of Mission and Kroneiki cultivars. Different parts of embryos were cultures in OMc medium containing growth regulators, such as indole butyric acid (IBA) and 2-isopentenyl adenine (2-ip) or IBA and naphthalene acetic acid (N...

Growth of an auxin-requiring soybean cotyledon callus tissue (Glycine max L., Merr. var. Acme) was promoted by tryptophan, tryptamine, indole, indoleacetamide and, to a very slight degree, anthranilic acid. When tryptophan-3-(14)C was supplied in the growth medium, labeled indoleacetic acid (IAA) was found in both the tissue and the medium. Medium, from which the cells had been removed, was als...

Carbamoyl phosphate synthetase activity was measured in partially purified extracts from cotyledons of developing and germinating seeds of Pisum sativum L. Some properties of the enzyme were established. During cotyledon development, the activity initially increased sharply but decreased during further development. The activity from germinating seeds was only one-tenth of the maximum activity a...
