In this experiment the effect of inoculation with Azospirillum on the flag leaf and spike rachis anatomical features and also on grain yield and grain weight was investigated for the first time in bread and durum wheats during 2015-2016 growing season under semi-arid condition. The crop yield increased due to the inoculation with Azospirillum with a maximum yield increase of about 8.0 per cent ...

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...

Pimpinella anisum L. belongs to Apiaceae family. The samples of vegetative and reproductive organs at different stages of development were gathered and investigated by cell-histology methods. The investigation of the anatomical structure of vegetative organs showed that the secretory ducts are arranged between the parenchymal tissues of the leaf. Section of flower buds revealed that anthers had...

Leaf hydraulic conductance (KLeaf) is a measure of the efficiency water transport through leaf, which determines physiological parameters such as stomatal conductance, photosynthesis and transpiration rates. One key anatomical structure that supports KLeaf leaf venation, could be subject to evolutionary pressure in dry environments. In this context, it useful assess these traits species from ar...

The anatomical structure of mesophyll tissue in the leaf is tightly connected with many physiological processes in plants. One of the most important mesophyll parameters related to photosynthesis is the internal leaf surface area, i.e. the surface area of mesophyll cell walls exposed to intercellular spaces. An efficient design-based stereological method can be applied for estimation of this pa...

BACKGROUND Biomass recalcitrance is affected by a number of chemical, physical and biological factors. In this study we looked into the differences in recalcitrance between two major anatomical fractions of wheat straw biomass, leaf and stem. A set of twenty-one wheat cultivars was fractionated and illustrated the substantial variation in leaf-to-stem ratio between cultivars. The two fractions ...

The genus Astrantia L. is a perennial plant which belongs to the Umbelliferae family and is represented by only A. maxima Pallas which has two subspecies (subsp. maxima and subsp. haradjianii (Grintz.) Rech. fil.) in Turkey. Subsp. haradjianii is endemic and very common. In this study, Astrantia specimens were collected from different localities and investigated for morphological and anatomical...
