Phytotoxicity of Thiocyanate to Rice Seedlings

Bulletin of Environmental Contamination and Toxicology, 2012
The acute toxicity of potassium thiocyanate (KSCN) and ammonium thiocyanate (NH(4)SCN) to rice seedlings was tested. Hydroponically-grown plants showed different responses to the two species of thiocyanate. NH(4)SCN caused more severe stress to rice seedlings than KSCN.

Puddled Soil and Rice Seedling Characteristics Affecting Rice Seedling Withdrawal Force

Transactions of the ASAE, 1989
ABSTRACT THE effect of puddled soil and rice seedling characteristics on the rice seedling withdrawal force was determined in a laboratory study. Rice seedling withdrawal force is a good index of seedling anchorage in puddled soil. The goal of this study was to obtain fundamental information on rice seedling and puddled soil characteristics needed for ...

Morphogenesis of Rice and Arabidopsis Seedlings in Space

Journal of Plant Research, 1999
Seedlings of rice (Oryza saliva L.) and Arabidopsis (A. thaliana L.) were cultivated for 68.5 hr in the RICE experiment on board during Space Shuttle STS 95 mission, and changes in their growth and morphology were analyzed. Microgravity in space stimulated elongation growth of both rice coleoptiles and Arabidopsis hypocotyls by making their cell walls ...

Regulation of growth in rice seedlings

Journal of Plant Growth Regulation, 1983
Etiolated rice seedlings (Oryza sativa L.) exhibited marked morphological differences when grown in sealed containers or in containers through which air was passed continuously. Enhancement of coleoptile and mesocotyl growth and inhibition of leaf and root growth in the sealed containers (“enclosure syndrome”) were accompanied by accumulation of CO2 ...

Agmatine deiminase in rice seedlings

Phytochemistry, 1985
Abstract Agmatine deiminase activity in rice embryos increased gradually upto 24 hr during germination and then decreased. Gibberellic acid and kinetin inhibited the activity when added to the germination medium. The enzyme was purified 717 fold with specific activity 788.5 nkat/mg protein and yield 8.8%.

Variation in the nitrate reductase of rice seedlings

Planta, 1972
Nitrate reductase was induced in rice seedlings by nitrate and by chloramphenicol. During the induction period the different enzyme activities associated with nitrate reductase increased to different degrees. Nitrate induced high NADH-nitrate reductase activity and a great increase in the NADH-cytochrome c reductase activity which was associated with ...

Dissemination of weeds with rice seedlings

Tropical Pest Management, 1988
Abstract Dissemination of weed seeds, weed seedlings, and shoots of perennial weeds along with transplanted rice (Oryza sativa L.) seedlings was observed in farmers’ fields in Guimba, Nueva Ecija, Philippines. The percentage of weed seedlings and shoots in bundles of rice seedlings to be transplanted into the field ranged from 4–5 to 14.2% in the wet ...

Phasic Development of Rice Seedlings

Agronomy Journal, 1997
AbstractA better understanding of growth and developmental processes of rice (Oryza sativa L.) seedlings is necessary for crop management and modeling perspectives. This experiment was conducted to identify preautotrophic phases of rice seedlings, quantify seed dry matter mobilization and utilization, characterize dry matter partitioning during early ...
