Three species of Eremurus M. Bieb. grown at UASVM Iasi, Romania, were studied: E. himalaicus Baker, robustus Regel and stenophyllus (BOISS. & BUHSE) Bak. Some ornamental (morphologic phenologic) features analyzed also the anatomic structure leaf, content photosynthetic pigments enzymatic activity leaves. The biometrical phenological determinations indicate a good ecological adaptability pla...

L-glycine and L-cysteine, exhibit strong inhibition of partial purified PPO of wild pear. The concentration of L-glycine inhibiting PPO activity by 50% (IC ) was 0.8 and 0.5 mM for catechol oxidation and 50 0.75 and 0.5 mM for pyrogallol oxidation at pH 5 and 7, respectively. IC for L-cysteine calculated, 0.6 and 0.35 50 for catechol oxidation and 0.55 and 0.75 mM for pyrogallol oxidation at pH...

First report of 'Candidatus Phytoplasma trifolii' associated with leaf reddening and upright growth in pears (Pyrus communis L.) | Mustafa Usta, Abdullah Güller, Hikmet Murat Sipahioğlu Agricultural Journals

Aging cylinders excised from ;Golden Delicious' apple (Pyrus malus L.) pulp, like the intact fruit, exhibit some characteristic phenomena such as rise in respiration (climacteric), ethylene synthesis, enzymic changes, and increase in ribosomes and mRNA. Aging of cylinders of pulp tissues may offer a useful physiological tool for the study of maturation and senescence.

Background: Nepeta menthoides Boiss & Buhse is a species from Lamiaceae family. It is used as a herbal medicine with common name “Ostokhodus” in Iranian traditional and folk medicine but there is not enough information about its quality and quantity control methods. Objective: In this study we use micromorphological and phytochemical evaluations for qualitative and quantitative control of N. me...

Plastid genomes exhibit different levels of variability in their sequences, depending on the respective kinds of genomic regions. Genes are usually more conserved while noncoding introns and spacers evolve at a faster pace. While a set of about thirty maximum variable noncoding genomic regions has been suggested to provide universally promising phylogenetic markers throughout angiosperms, appli...

The flowers of Hyaloseris salicifolia afforded known ivasperin, while the leaves afforded ivasperin and 2-O-(6'-O-acetyl-beta-D-glucopyranosyl)-ivasperin, whose structure was determined by spectroscopic methods.

d'Anjou cv. pear fruit (Pyrus communis L.) exposed at harvest to 0, 0.42, 4.2, or 42 micromol m(-)(3) 1-methylcyclopropene (1-MCP) for 12 h at 20 degrees C were stored at 1 degrees C for up to 8 months. After storage, half of the fruit was continuously exposed to ethylene (0.45 or 4-18 mmol m(-)(3)) for 7 days at 20 degrees C. All fruit treated with 1-MCP had lower respiration and ethylene prod...
