Introduction: In May 2008 the Phoenix Lander descended into the north polar region of Mars. It landed at 68.22 N, 234.25 E in a shallow valley about 20 km west of a 10 km crater named Heimdall. Phoenix imaged local geomorphology, determined local ice table depth and analyzed 19 soil samples from within a ~15 m 2 work volume. Important to

This paper described the extraction procedure and determination method for the total flavonoids in ethanol extract from the leaves of Abutilon theophrasti Medic., and evaluated antibacterial and antioxidant activity. Maximum extraction yield was achieved using 60% ethanol, 1 : 30 (g/mL) of a ratio of material to solvent, 20 min of extraction time, 40 kHz of ultrasonic frequency, 100 W of ultras...

We grew velvetleaf (Abutilon theophrasti Medic.) and cotton (Gossypium hirsutum L. var. Stoneville 213) at three irradiances and determined the photosynthetic responses of single leaves to a range of six irradiances from 90 to 2000 mueinsteins m(-2)sec(-1). In air containing 21% O(2), velvetleaf and cotton grown at 750 mueinsteins m(-2)sec(-1) had maximum photosynthetic rates of 18.4 and 21.9 m...

( )-Cryptocaryalactone (6-[2-acetoxY-4-phenyl-3-butenyl}5,6-dihydro-2-pyranone) and ()-deacetylcryptocaryalactone (6-[2-hydroxy-4-phenyl-3-butenyIJ-5,6-dihydro-2-pyranone) isolated from Cryptocarya moschata seeds are natural germination inhibitors. Applied at 0.004 M, the second compound completely arrested germination of velvetleaf (Abulilolllheophrasli) and decreased the germination rate of s...

date bunch fading disorder (dbfd) has been one of the major issues facing date palm growers in recent decades. this order has caused high and non-compensable losses to date palm product. despite numerous studies, predominantly focusing on the causes and mitigation methods of this disorder, no precise influencing factors have been established and practices which can completely control it are not...

Greenhouse studies were conducted to evaluate the effects of soil organic matter content and pH on initial residual weed control with flumioxazin by planting selected species in various lab-made field soils. Initial was determined seeds into soils treated (71 g ha−1). Seeds Echinochloa crus-galli (barnyard grass), Setaria faberi (giant foxtail), Amaranthus retroflexus (redroot pigweed), Abutilo...

A crude acetone extract of the pit of date palm (Phoenix dactylifera L.) was prepared and its antiviral activity evaluated against lytic Pseudomonas phage ATCC 14209-B1, using Pseudomonas aeruginosa ATCC 25668 as the host cell. The antiviral activity of date pits was found to be mediated by binding to the phage, with minimum inhibitory concentration (MIC) of <10 μg ml(-1). The decimal reduction...
