Spectral reflectance curves to distinguish soybean from common cocklebur (Xanthium strumarium) and sicklepod (Cassia obtusifolia) grown with varying soil moisture
Lori M. Bruce Hrishikesh D. Tamhankar Department of Electrical and Computer Engineering, Mississippi State University, Mississippi State, MS 39762 Experiments were conducted to examine the use of spectral reflectance curves for discriminating between plant species across moisture levels. Weed species and soybean were grown at three moisture levels, and spectral reflectance data and leaf water p...
متن کاملdormancy breaking of cocklebur (xanthium strumarium l.) seeds
in order to investigate the environmental factors including temperature, moisture, and plant hormones on dormancy breaking of seeds of xanthium strumarium l. a number of experiments were conducted. x. strumarium seeds were dormant soon after being harvested. seed germination of cocklebur increased through a combination of cooling, temperature fluctuations following ripening. most seed germinati...
متن کاملEthnobotanical, phytochemical and toxicological studies of Xanthium strumarium L.
The present study describes the ethnobotanical, phytochemical, and toxicological evaluations of Xanthium strumarium L. growing in Bangladesh. In toxicity evaluation on rats, the methanol extract of seedlings showed mortality, while both seedling and mature plant extracts raised the serum alanine transaminase and aspartate transaminase values and produced significant abnormalities in the histopa...
متن کاملBiological activities of xanthatin from Xanthium strumarium leaves.
The objective of the present work was to evaluate the biological activities of the major bioactive compound, xanthatin, and other compounds from Xanthium strumarium (Asteraceae) leaves. Inhibition of bloodstream forms of Trypanosoma brucei brucei and leukaemia HL-60 cell proliferation was assessed using resazurin as a vital stain. Xanthatin was found to be the major and most active compound aga...
متن کاملAnalytical confirmation of Xanthium strumarium poisoning in cattle.
Xanthium strumarium, commonly referred to as "cocklebur," rarely causes poisoning in cattle. When mature, this robust, annual weed bears numerous oval, brownish, spiny burs. Only the seeds in the burs and young seedlings (cotyledonary leaves) contain the toxic principle, carboxyatractyloside. In the Frankfort district of the Free State Province of South Africa, a herd of 150 Bonsmara cows were ...
