Abstract The paper presents the results of a study decorativeness pines, which are actively grown on territory European part Russia. Decorativeness is based visual perception plant habitus. state habitus depends genotype and adaptive characteristics in certain growing conditions. examined 25 decorative features 56 species. 24 traits were related to vegetative generative organs. 1 trait was asse...

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...

Drought stress, as the most important environmental stress, severely disrupts plant growth and limits production and yield more than any other environmental factor. Investigation of the role of drought stress conditions on plant morphological, physiological and photosynthesis characteristics may provide a tool to understand the basic drought resistance. To investigate the drought tolerance of I...

The cultivation of dry-season sorghum on residual moisture in West and Central Africa is highly affected by sowing dates ecotypes used. Fifty-five collected from three zones southern Chadian were sown two dates, early late, 2013 2014, an α-Lattice, replicated five times to evaluate the effect date potential yield, flowering time, other agro-morphological traits determine their photoperiod sensi...

Winter oilseed rape (WOSR) is Europe’s prime crop and grown for biofuel edible oil production. To investigate the effects of climate change on yield winter rape, two models (HERMES HUME-OSR) were used. This study investigated sensitivity model parameters (as a proxy plant traits) under change. For both models, global analysis was performed current temperatures, an increase 2 4 °C, in combinatio...

This investigation was carried out to determine the effects of gamma radiation on germination characteristics gladiolus corms. experiment conducted through a factorial design in randomized complete block with three replications. Two factors included cultivars (Red Advance, White Prosperity, Amsterdam, and Rose Supreme) doses (0, 15, 25, 35, 45, 55, 65, 75 Gy). The results showed that corm weigh...

A stay-green phenotype enables crops to retain green leaves longer after anthesis compared with senescent types, potentially improving yield. Measuring the normalized difference vegetative index (NDVI) during the whole senescence period allows quantification of component stay-green traits contributing to a stay-green phenotype. These objective and standardized traits can be compared across geno...

Alopecurus myosuroides Huds. (black-grass) has always been a major concern for cereal growers, and the development of herbicide resistance does not improve the situation. This review article summarizes the different traits involved in the dispersal pattern of herbicide resistant black-grass individuals within a susceptible field population. Therefore, the whole life cycle of black-grass is depi...

Leaf ecophysiological traits related to carbon gain and resource use are expected to be under strong selection in desert annuals. We used comparative and phenotypic selection approaches to investigate the importance of leaf ecophysiological traits for Helianthus anomalus, a diploid annual sunflower species of hybrid origin that is endemic to active desert dunes. Comparisons were made within and...
