The objectives of this study were to evaluate the tolerance to low temperatures and tuber soft rot in hybrids between Solanum com! mersonii and Solanum tuberosum[ The experimental materials consisted of F0 triploid\ BC0 pentaploidÐnear pentaploid and BC1 tetraploidÐ near tetraploid hybrids[ The F0 triploids had a freezing tolerance and acclimatization capacity closest to S[ commersonii[ This in...

Rhizomes of Acorus calamus L. were able to maintain a functional alpha-amylase under anoxia, whereas a steep decrease in the enzyme protein content and activity took place in potato tubers. The stress-induced control in tubers occurred on the translational level. It is suggested that this decrease is one of the key factors with regard to anoxia intolerance.

Individual leaves of potato (Solanum tuberosum L. W729R), a C(3) plant, were subjected to various irradiances (400-700 nm), CO(2) levels, and temperatures in a controlled-environment chamber. As irradiance increased, stomatal and mesophyll resistance exerted a strong and some-what paralleled regulation of photosynthesis as both showed a similar decrease reaching a minimum at about 85 neinsteins...

The major cultivated potato, Solanum tuberosum, and six other related cultivated species, are hypothesized to have arisen from a group of weedy relatives indigenous to the central Andes of central Peru, Bolivia, and northern Argentina. A major problem hindering investigations of the origins of the cultivated species has been a continuing debate over the species boundaries of their putative prog...

In this study, field experiment was conducted to assess the effect of different doses NPK on tuber yield potato (Solanum tuberosum L.) varieties such as Inovator, Gala, Aladin and Tyanshansky in foothill zone southeast Kazakhstan. Five combinations with control were studied. Results revealed that fertilizer application increased total yield, longest plant, number main stem, leaves plant average...

This work describes the development of a fast and efficient methodology for Agrobacterium tumefaciens-mediated genetic transformation of internodal stem segments from potato (Solanum tuberosum L.), cultivar Désirée, using phosphinothricin (PPT, glufosinate ammonium) as a selection agent. This methodology has a transformation efficiency of 68%, inducing shoots after 4 to 5 weeks in the presence ...

Glutathione S-transferases (GST) form a large family of non-photosynthetic enzymes known to function in detoxification of xenobiotics. We have cloned and characterized a novel, low temperature regulated GST, Solanum commersonii glutathione S-transferase (Scgst1), from a cold acclimated wild potato species S. commersonii and studied the level of its transcription in freezing tolerant and sensiti...

Las variedades de papa (Solanum tuberosum L.) producidas en México son susceptibles a Candidatus Liberibacter solanacearum (CaLso), causante la enfermedad conocida como ‘manchado interno pulpa’, por lo que se requiere conocer respuesta genotipos experimentales bacteria. El presente estudio tuvo objetivo evaluar el efecto infección los haplotipos LsoA + LsoB CaLso follaje, biomasa seca y calidad...

The hypoglycemic effect of feeding normal and alloxan-induced diabetic rats with Sweet Potato (Ipomoea batatas)and Irish (Solanum tuberosum)flour fortified vitamin for 21 days was studied. Forty-five white albino were divided into groups five each. are Normal control, control + diet, positive negative test 1 2. Fasting blood glucose 2 hours post-prandial measured at 7 days, 14 days. It found th...
