Purple nutsedge [Cyperus rotundas L.) has been recognized as one of the
most troublesome perennial weeds of agricultural lands in tropical and some
temperate regions. This research sought to determine the effects of timing of
herbicides, shading, and soil moisture on plant population growth and tuber
production of purple nutsedge...
Most of the presently grown cultivars of rice (Oryza sativa L.) have poor
competitive ability against weeds if compared with traditional cultivars. Therefore,
effective weed control is an important but often costly and difficult management
practice in rice crop production. If weed competitive ability of rice cultivars could be
improved...
Green bean flavor has been studied since the 1960’s to better understand Blue Lake flavor in processed green beans in Oregon. Research by Stevens and colleagues showed that Blue Lake flavor could be reconstituted in a bland bean by adding 0.4ppm of 1-octen-3-ol and 1.6ppm of 3-hexen-1-ol. These two volatile...
Penetration of ¹⁴C-labeled plant growth regulators into the surface of apple
(Malus pumila M.) leaves pre-soaked in 10 ml I⁻¹ solutions of surfactant was
measured by detecting changes in radioactivity of the solution in glass cylinders
sealed to the astomatal, adaxial surface of the leaf discs. Penetration of 2,4-D
[(2,4-dichlorophenoxy)acetic...
