in order to assess the effect of salinity constraint on some agro-physiological and biochemical traits in medicago sativa l., four alfalfa populations (tafilalet 1, tafilalet 2, demnate and tata), originated from mountains and oasis of morocco, were tested. the plants were grown under greenhouse conditions in pots filled with sand and peat under three salt treatments (0, 100 and 200 mm nacl). t...

In a free viewing learning condition, participants were allowed to move their eyes naturally as they learned a set of new faces. In a restricted viewing learning condition, participants remained fixated in a single central location as they learned the new faces. Recognition of the learned faces was then tested following the two learning conditions. Eye movements were recorded during the free vi...

Abstract Lettuce is a crop sensitive to water availability as it needs more in cultivation. Kaolin has been reported reduce the impact of drought stress plants. However, use kaolin increase lettuce growth under condition not yet. In this study, effect suboptimal watering was investigated. foliar application (3%, 5%, and 6%) tested on group consisting 5 plants grown reduced greenhouse. height, n...

background & aim: medicinal plants can be a good replacement for common cancer treatment including chemotherapy, radiation therapy and surgery because they don’t have many side effects. the aim of this study was to investigate the effect of temperature on the free radical scavenging in the presence of medicinal plants. experimental: for determination of free radical scavenging activity was...

During servicing operations, free-flying robots equipped with robotic arms are required to operate without disturbing the nearby environment through unwanted base oscillations. We present underlying theory, kinematic control software, and experimental results of a three-dimensional free-flying robot prototype able to follow a given trajectory with its end-effector while base movements are minim...

The castor bean is an important industrial and ornamental crop. In the industry, it used as a source of oil. Moreover, has large potential feed crop, because seeds contain high amount protein. A main problem with use presence toxins in plants. Today, detoxification carried out using various approaches, including biotechnological methods such CRISPR/Cas9 technology. successful application these ...

Chemical preservatives have been used in the food industry for many years. However, with increased health concerns, consumers prefer additive-free products or food preservatives based on natural products. This study evaluated antimicrobial activities of extracts from Emilia sonchifolia L. (Common name: lilac tassel flower), Tridax procumbens L. (Common name: tridax daisy) and Vernonia cinerea L...

The antifungal activity of eight different medicinal plants namely Aloe vera, Ocimum sanctum, Cenetella asiatica, Piper betle, Calotropis gigantea, Vitex negundo, Ocimum basilicum and Azadirachta indica were tested against plant pathogenic fungus (red rot disease causing agent) Colletotrichum falcatum by agar well –diffusion method. The plants leaves were extracted with various solvents like ch...
