In a five-year (2015-2019) study, some vegetative and generative peculiarities of two resistant apple cultivars (‘Galiwa’ ‘Story Inored’) were assessed in young orchard with multi-row training system. Based on our research, cv. ‘Galiwa’ showed significantly weaker growth, than Inored’, which was manifested lower trunk cross sectional area (TCSA) tree height. Cultivar Inored’ reached the optimal...

†Background and Aims The underlying evolutionary processes of pollinator-driven floral diversification are still poorly understood. According to the Grant–Stebbins model speciation begins with adaptive local differentiation in the response to spatial heterogeneity in pollinators. Although this crucial process links the microand macroevolution of floral adaptation, it has received little attenti...

abstract. information on forage quality in phenological stage could help range managers to choose suitable grazing method to achieve higher animal performance without detriment to vegetation. vetiver grass (vetiveria zizanioides) is a non-native perennial grass that was introduced to the iran in 2008. this plant is a multi use species that could be considered from different viewpoints. thus, it...

Mimicry has evolved in plants for a number of traits, both floral and vegetative. The discovery of a vine that mimics the leaf shape of different hosts poses new questions about the function of leaf mimicry, interplant signalling and leaf development.

Pollen formation, while critical for the success of plant reproduction, also represents an important paradigm for differential cellular development within small groups of cells. In Arabidopsis thaliana pollen, the male meiotic product first divides asymmetrically to form a vegetative and a generative (germ) cell, the latter then dividing to generate two sperm cells. Here we have used artificial...

this research was conducted to study some vegetative and reproductive traits as well as qualitative andquantitative characteristics and their correlation in 80 almond genotypes. qualitative traits were studiedaccording to gulcan descriptor. quantitative traits were analyzed as completely randomized design(crd), with 12 replications. the results showed that genotypes had significant difference i...

this research was conducted to compare plant functional types (pft) and traits in an old-field (abandoned for 28 years) and a control site, in the baharkish rangelands, quchan, iran. in the both sites, 40 randomized quadrates were established. floristic list, frequency, canopy cover and 20 vegetative, phenological and morphological plant traits were measured for all plant species, within each q...
