The odoriferous compounds produced at the time of flowering by the inflorescences of 5 arum lily species were condensed in dry ice traps. The components of the condensates were separated by paper chromatography and identified on the basis of position and color reactions in comparison with known compounds. The concentration of free amino acids in the appendix of Sauromatum guttatum Schott increa...

Sex allocation models predict that cosexuality is stabilized by high allocation to attractive structures in pollen-limited species or by high allocation to shared structures that contribute to both genders. High investment in unilateral fixed costs favor the evolution of dioecy or gender change. With these predictions in mind, I studied sexual mass allocation at flowering in the monoecious Arum...

The leaves of Arum conophalloides (Araceae) were used in some west areas of Iran as a dessert. The aerial parts of the herb were collected from Sahneh Mountains, Kermanshah Province, West of Iran and was hydrodistilled by Klevenger-type apparatus. Composition of the essential oil was determined by GC and GC/MS. Totally, 18 components (92% of total essential oil) were identified. The oil contain...

The effects of temperature upon the respiratory pathways of Arum maculatum mitochondria have been studied. The alternate oxidase sustained a greater proportion of the total respiration at low temperatures than at higher temperatures. Arrhenius plots of respiratory activities show two discontinuities, one at 14 degrees C and one at 21 degrees C. The lower temperature discontinuity was associated...
