The current investigation concluded an anatomical study of the cultivated species Pelargonium graveolens L. 'Hér belong to Geraniaceae family and which as ornamental plant, fresh specimen were collected from different region in Baghdad ,the vegetative parts (leaf, stem petiole) details upper lower epidermis leaf also studied, ordinary epidermal cells stomatal complexes studied term shapes dimen...

This research was carried out in order to compare among three different fertilizers: bio, chemical, and organic. on two plants selected conduct this were (Narcissus Hyacinths), which cultivated shaded non-shaded locations from Autumn 2020 Spring 2021 Gerdarash field at the college campus. The vegetative traits of plants, as well production bulblets, measured properly. Regarding Narcissus, bio-f...

This study investigated the effects of different PGRs on in vitro plant regeneration Anthurium scherzerianum Schott and acclimatization ex stage. Depending objective each experiment, shoots were induced from callus cultured a modified Murashige Skoog (MS) medium containing cytokinins auxins. Results showed that 90% leaf explants 48% petiole produced callus. A half-strength MS supplemented with ...

The variety of types otnogenetic tactics is shown on the example structural features leaf Betula pendula Roth growing under conditions technogenic soil transformation in Tagil zone Middle Urals (Sverdlovsk oblast). It has been established that structure this species contains are characterized by various ontogenetic tactics, both pure and combined. most represented convergent-divergent convergen...

A study has been made of the temperature control of translocation localized to regions of the stem, petiole and hypocotyl of Cucurbita melopepo. The basipetal and acropetal movement of translocated (14)C-labeled compounds in the phloem tissue, measured over a 45-minute period, was almost completely inhibited at 0 degrees . At 10 degrees a partial inhibition occurred while an extremely variable ...

Autoradiography was used to determine the distribution of labeled sugar in conducting elements of the blade and petiole of sugar beet leaves at intervals ranging from 5 sec to 24 hr. The processes of assimilation by the green cells, collection of sugar in the minor veins and export in phloem elements were demonstrated visually. It appears that in minor veins sugar is translocated in companion c...
