this study performed to evaluate genetic diversity of some wild and domesticated (unknown foreign cultivars) blackberries in sanru collection based on morphological traits. results showed high diversity for flowering, ripening time and fruit juice. wild genotypes showed significant differences in leaf, flower, thorn number, fruits and seed fresh weight compared to domesticated cultivars. based ...

Plants use their roots to forage for nutrients in heterogeneous soil environments, but different plant species vastly differ in the intensity of foraging they perform. This diversity suggests the existence of constraints on foraging at the species level. We therefore examined the relationships between the intensity of root foraging and plant body traits across species in order to estimate the d...

Phenology and time of flowering are crucial determinants of rice adaptation to climate variation. A previous study characterized flowering responses of 203 diverse indica rices (the ORYTAGE panel) to ten environments in Senegal (six sowing dates) and Madagascar (two years and two altitudes) under irrigation in the field. This study used the physiological phenology model RIDEV V2 to heuristicall...

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...

Obtaining high seed and oil yields of sunflower requires coincidence of vegetative and reproductive stages of growth of the plant with suitable environmental conditions via selecting appropriate planting date. Since the suitable date of planting for sunflower cultivars under Isfahan environmental conditions was not determined, this experiment was conducted in 1996 at the Agricultural Research S...

Large and diverse genera, such as Silene need more reliable morphological traits for the credible identification and delimitation of the species. Despite the fact that the type of indumentum among the species of Silene had been addressed in most available revisions, monographs and floristic studies, the trichome-based features and their adaptational importance have not been investigated explici...

Oil palm propagation techniques are juvenile pot plants derived from germinated seeds and tissue culture, because it doesn’t produce sucker. In the nursery stage, monitoring the conditions of irrigation and nutrition are important to ensure phenotypic quality. During the nursery stage, optimal fertilization in development of more vigorous and productive plants. This research was carried out to ...
