Histological Distribution of Anthocyanins in Anthurium Spathes

Leuco-anthocyanins. 2. Systematic distribution of leuco-anthocyanins in leaves.

In Part 1 (preceding paper) a method of demonstrating the presence of leuco-anthocyanins in plant tissues has been described. A modified version of this method, in which paper chromatographic separation of the anthocyanidins is not carried out, has been applied to the leaves of several hundred species of plants. As a confirmatory test, in the great majority of instances the vanillin reaction ha...

coordination of protective schemes in distribution and subtransmission systems including distributed generation

نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...

Differentiated Microelement Content in Anthurium (anthurium Cultorum Birdsey) Leaves*

The main objective of the study was to determine the nutritional status in terms of the content of microelements, such as iron, manganese, zinc, copper and boron in several standard cultivars of anthurium (Anthurium cultorum Birdsey) called Baron, Choco, Midori, Pistache, President and Tropical. The plants were grown in expanded clay (ř 8-18 mm) using drip fertigation with standard nutrient for...

Somatic embryogenesis in anthurium (Anthurium andraeanum cv. Eidibel) as affected by different explants

This study establishes a protocol for the induction of somatic embryogenesis in Anthurium andraeanum cv. Eidibel. The experiment was arranged in a completely randomized 5 x 5 x 5 factorial design using five explant types (whole leaves, half leaves; petiole; nodal segments and root segments) from in vitro plantlets; five auxins: indole-3-acetic acid (IAA), α-naphthaleneacetic acid (NAA), indole-...
