In a conifer tree, such as Nordmann fir, Abies nordmanniana Spach, the leader bud and its immediate surroundings play a decisive role in crown architecture. As subapical branch buds are segregated from the leader meristem, resource allocation between

Flowers of tulips (17 species and 25 cultivars) were subjected to qualitative and relative quantitative examination for anthocyanins. Altogether five anthocyanins were identified as the 3- O -(6″- O -α-rhamnopyranosyl-β-glucopyranoside) of delphi

From the flower extracts of Crocus speciosus and C. antalyensis nine flavonol glycosides have been isolated. One of these products is a new flavonol glycoside identified as kaempferol 3-O-alpha-(2,3-di-O-beta-D-glucopyranosyl)rhamnopyranoside by UV,

The perianth segments of 10 cultivars including Asiatic and Oriental hybrids and one species of Lilium, were investigated by HPLC for their content of anthocyanins. The investigation revealed the presence of one new and one known anthocyanin. The nov

Involvement of cytokinins (CKs) in axillary bud growth of miniature rose was studied. Variation in root formation and axillary bud growth was induced by two indole 3-butyric acid (IBA) pretreatments in two cutting sizes. At six physiological developm
