Sugar transport in conducting elements of sugar beet leaves.
Autoradiography was used to determine the distribution of labeled sugar in conducting elements of the blade and petiole of sugar beet leaves at intervals ranging from 5 sec to 24 hr. The processes of assimilation by the green cells, collection of sugar in the minor veins and export in phloem elements were demonstrated visually. It appears that in minor veins sugar is translocated in companion c...
متن کاملRhizoctonia stem canker and black scurf of potato
Rhizoctonia stem canker and black scurf diseases of potato are caused by the fungus Rhizoctonia solani Kühn (teleomorph Thanatephorus cucumeris [A. B. Frank] Donk) and can be found on all underground parts of the plant at various times during the growing season. Rhizoctonia solani (Deuteromycetes, Mycelia Sterilia) is a species complex of 13 anastomosis groups (AGs), which are categorized accor...
متن کاملEarly iron deficiency stress response in leaves of sugar beet.
Iron nutrient deficiency was investigated in leaves of hydroponically grown sugar beets (Beta vulgaris) to determine how ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) gene expression is affected when thylakoid components of photosynthesis are diminished. Rubisco polypeptide content was reduced by 60% in severely iron-stressed leaves, and the reduction was directly correlated to chlo...
متن کاملEffects of potassium deficiency on the photosynthesis and respiration of leaves of sugar beet.
Sugar beet plants (Beta vulgaris L. var. F5855441) were germinated and cultured under standardized environmental conditions for 28 days. Potassium deficiency was then induced by withholding K from the culture solution. Changes in CO(2) and water vapor exchange rates and surface temperatures of individual attached leaves were measured with time after K cut-off, along with changes in the concentr...
متن کاملEffects of phosphorus deficiency on the photosynthesis and respiration of leaves of sugar beet.
Phosphorus deficiency was induced in sugar beet plants (Beta vulgaris L. var. F5855441), cultured hydroponically under standardized environmental conditions, by removal of phosphorus from the nutrient supply at the ten leaf stage 28 days after germination. CO(2) and water vapor exchange rates of individual attached leaves were determined at intervals after P cutoff. Leaves grown with an adequat...
