Development in Norway Spruce, Picea abies'
A pulse-treatment of embryos of Picea abies (L.) Karst with cytokinin efficiently and reproducibly induces the coordinate de novo formation of bud primordia from subepidermal cells. The cytokinin treatment also affects the germinative development of the embryo; chloroplast maturation is delayed, and cell elongation is completely suppressed. We have analyzed the protein patterns in developing sp...

Umbelliferone, Quantitative Estimation, Picea abies, Genetic Families A compound showing blue fluorescence under UV-light was isolated from spruce needles and identified as umbelliferone. Structure analysis was based on UV and mass spectroscopy as well as chromatographic comparison with authentic material. Quantitative evaluation by direct measure ment of the fluorescence of the umbelliferone ...
متن کاملبررسی میزان موفقیت Picea abies در جنگلکاری‌های استان گیلان
گونه نوئل Picea abies (L) Karst قلمرو نسبتاً وسیعی را در جهان به‌خود اختصاص داده و در برنامه‌های جنگل‌کاری بسیاری از کشورهای جهان قرار گرفته است. ریشه‌دوانی متراکم و سطحی و حساسیت به باد و برف از ویژگی‌های این گونه می‌باشد و در رویشگاه‌های طبیعی خود با رشد قابل توجه (40 متر ارتفاع و 1 تا 1/5 متر قطر) گزارش شده است. این گونه در دهه 1340 وارد ایران شد و در دهه 1350 در برنامه جنگل‌کاری گیلان قرار گ...
متن کاملCell Wall-Bound Phenolics from Norway Spruce (Picea abies) Needles
Secondary products, such as phenolics, accumulate predominantly in the form of hydrophilic conjugates in the vacuoles (intraprotoplasmic storage) of plants [1—3]. Also there are many reports on their extraprotoplasmic location, e.g. as exudates [4] or cell wall components. The latter include the polymer lignin [5], as well as monomeric hydrolyzable phenolics, which are mainly hydroxycinnamic ac...
متن کاملAn acetylated galactoglucomannan from Picea abies L. Karst.
A water-soluble galactoglucomannan composed of D-galactose, D-glucose, and D-mannose in 1:3:17 mole proportion has been isolated from the secondary cell walls of Picea abies L. Karst. About 33% of the polysaccharide units were substituted by acetyl groups. Structural studies of the polymer indicated a beta-(1-->4)-linked glucomannopyranosyl backbone with a low content of branch points at O-6 of...
