Microtuberization of Potato (Solanum tuberosum) under Saline Stress

In vitro microtuberization in potato (Solanum tuberosum L.) cultivars.

Mechanism of microtuberization in three elite cultivars kufri badhsha (KB), kufri chandramukhi (KCM) and kufri jawahar (KJ) of potato was studied. Sprouts of all the three cultivars were used to obtain in vitro shoot cultures. MS medium supplemented with chlorocholine chloride was found to be most suitable for all the cultivars. Maximum tuberization was obtained under incubation conditions of c...

Effects of Nitrogen and Potasium on in vitro Microtuberization of Potato (Solanum tuberosum L. var Agria)

Optimum concentrations of nitrogen and potassium on in vitro microtuberization of Agria, a popular variety of Potato, Solanum tuberosum L., were evaluated. The concentrations of 0, 0.5, 1, 1.5, and 2 folds of standard concentrations of NH4NO3 (1650 mgl) and KNO3 (1900 mgl) were used in Murashige and Skoog (MS) medium, and their effects were studied on cell number, cell sizes, and number of amid...

Ultrastructural and physiological responses of potato (Solanum tuberosum L.) plantlets to gradient saline stress

Salinity is one of the major abiotic stresses that impacts plant growth and reduces the productivity of field crops. Compared to field plants, test tube plantlets offer a direct and fast approach to investigate the mechanism of salt tolerance. Here we examined the ultrastructural and physiological responses of potato (Solanum tuberosum L. c.v. "Longshu No. 3") plantlets to gradient saline stres...

Transcriptome Profiling of the Potato (Solanum tuberosum L.) Plant under Drought Stress and Water-Stimulus Conditions

Drought stress can seriously affect tuberization, yield and quality of potato plant. However, the precise molecular mechanisms governing potato stolon's response to drought stress and water supply are not very well understood. In this work, a potato (Solanum tuberosum L.) variant, Ningshu 4, was subjected to severe drought stress treatment (DT) and re-watering treatment (RWT) at tuber bulking s...
