Weed control is one of the most important technological operations to ensure crop yield and quality in ecological sugar beet production. However, conventional mechanical weed labor- time-intensive has adverse effects on soil environment. The aim this study was experimentally investigate influence robotic systems properties assess effectiveness these different methods This examines two systems: ...

A procedure to remove vibrato from singing voice was proposed to enable auditory morphing between musical performances played under different conditions. Analyses of singing samples in the RWC music database using a speech analysis, modification and synthesis system STRAIGHT provided necessary information to implement “senza vibrato,” the procedure that removes vibrato. A preliminary subjective...

Limited data are available on the sulfur (S)-mediated-alleviation of aluminum (Al)-toxicity in higher plants. Citrus grandis seedlings were irrigated for 18 weeks with 0.5 mM MgSO₄ or 0.5 mM MgSO₄ + 0.5 mM Na₂SO₄, and 0 (-Al) or 1 mM AlCl₃·6H₂O (+Al, Al-toxicity). Under Al-toxicity, S decreased the level of Al in leaves; increased the relative water content (RWC) of roots and leaves, the conten...

Water relations of Engelmann spruce (Picea engelmannii Parry) and subalpine fir (Abies lasiocarpa (Hook.) Nutt.) trees growing at an elevation of 3230 m on Mt. Evans, Colorado, USA, were studied during the winters of 1995-1996 and 1996-1997. During both winters, current-year and 1-year-old shoots were collected weekly and their relative water contents (RWC) determined. Measured meteorological p...

Water retaining agent (WRA) is widely used for soil erosion control and agricultural water saving. Here, we evaluated the effects of the combination of beneficial soil bacterium Bacillus amyloliquefaciens strain GB03 and WRA (the compound is super absorbent hydrogels) on drought tolerance of perennial ryegrass (Lolium perenne L.). Seedlings were subjected to natural drought for maximum 20 days ...

Frequent monitoring of stress levels in turfgrass is key to maintaining healthy turfgrass stands. Current methods used to monitor turfgrass for drought and salinity stress can be time consuming and expensive. This study was conducted to determine if data obtained from digital image analysis and spectroradiometry could accurately detect drought and salinity stress in hybrid bluegrass. Furthermor...

Dehydration affects the photosynthetic apparatus. The impact of dehydration on photosynthesis was assessed in twelve Mediterranean species representing different growth forms. Rapid and slow experiments were conducted to (1) compare water stress among forms, (2) rank according their drought tolerance. reduced electron transport up PSI, reduction being linearly related leaf relative content (RWC...

One of the most significant abiotic factors that has a negative impact on wheat productivity globally is drought. To comprehend impacts drought and propose remedies, numerous studies are carried out various varieties. In this study, 50 µM methyl jasmonate (MeJA) was applied to tolerant Gün 91 sensitive Bezostaja cultivars they were exposed stress for 15 days. The responses MeJA application deve...

Water distribution systems (WDSs) are becoming equipped with advanced feedback loops, which require specialized methods and software tools to model such systems. The aim of this work is demonstrate the usefulness rigid water column (RWC) analyze dynamic interactions between these loops system stability. Our fills gap extended period simulation, used for steady state analysis, transient surge an...

drought stress is a major factor limiting crop production. investigation of physiological characteristics related to drought tolerance and crop production may be useful in selecting drought tolerant cultivars as well as in improving crop yield. two drought tolerant (azar2 & back cross roshan) and two drought susceptible (marvdast & shiraz) cultivars were investigated in both greenhouse and fiel...
