Kinetin induces formation of red pigment in seedlings of Amaranthus retroflexus in the dark. This effect is similar to the light-induced formation of pigment. Light and kinetin do not act in a simple additive way. The pigment is not an anthocyanin, and its formation is not affected by inhibitors of anthocyanin formation.
The sponge Phorbas amaranthus from Florida contains the new ring A-contracted steroids, phorbasterones A-D, and the known anthosterones A and B. The structures of phorbasterones A-D were determined by interpretation of their spectroscopic data. Phorbasterones show moderate cytotoxicity against HCT-116 tumor cells.
بیماریهای قلبی عروقی همواره موجب مرگ انسانهای زیادی در جهان می شود وخسارتهای جانی و مالی زیادی را به دنبال دارد. فاکتورهای التهابی و انعقادی از ریسک فاکتورهای مهم بیماریهای قلبی عروقی می باشند. در این مطالعه، اثر ترکیب عصاره های دو گیاه گل راعی (hypericum perforatum l.) و تاج خروس (amaranthus caudates l.) بر روی برخی از فاکتورهای التهابی و انعقادی در بیماری قلبی و عروقی در خرگوشهای هایپرکلسترول...
Consumption of food contaminated with heavy metals is a major source of health problems for man and animals. Vegetable cropping along major highways with heavy vehicular movement has been a serious concern to food safety experts in large cities. A study was, therefore, carried out in two major highways in Lagos, Nigeria to determine the extent of lead (Pb) and cadmium (Cd) contamination in vege...
The traditional study of infant locomotion focuses on what movements look like at various points in development, and how infants acquire sufficient strength and balance to move. We describe a new view of locomotor development that focuses on infants' ability to adapt their locomotor decisions to variations in the environment and changes in their bodily propensities. In the first section of the ...
Hairy vetch is a leguminous winter annual cover crop that provides a significant contribution toward meeting the nitrogen requirement of succeeding crops. Hairy vetch residue is capable of suppressing weeds, but low levels of residue can intermittently stimulate the emergence of weeds, particularly smooth pigweed. This research was conducted to assess the inhibitory and stimulatory effects of h...
Consumption rates, development times, and life table parameters of the beet armyworm, Spodoptera exigua (Hübner), were determined on Þve host plants: cabbage, Brassica oleracea capitata L; cotton, Gossypium hirsutum L.; bell pepper, Capsicum annuum L.; pigweed, Amaranthus retroflexus L.; and sunßower, Helianthus annuus L. Mean total leaf weight consumed by larvae was highest in cabbage (2.7 g) ...
This study found that 7-, 9-, and 11-year-old children and young adults identified prosocial lies as lies less frequently and evaluated them less negatively than selfish lies (liar intention effect); lies about opinions were identified as lies less frequently and evaluated less negatively than those about reality (lie content effect). The lie content effect was more pronounced in the prosocial ...
Grain Amaranth is a very versatile pseudo-cereal crop and grown in a wide range of agro-climatic conditions (temperature 20-40oC, elevation 500-2500m amsl and rainfall 800 mm to 1500 mm). The genus Amaranthus consists of approximately 60 species out of which about 18 species are occurring in India. There are three major grain producing Amaranthus species, A. caudatus, A. cruentus and A. hypocho...
Conservation tillage reduces the physical movement of soil to the minimum required for crop establishment and production. When consistently practiced as a soil and crop management system, it greatly reduces soil erosion and is recognized for the potential to improve soil quality and water conservation and plant available water. Adoption of conservation tillage increased dramatically with the ad...
