Salinity and potassium fertilizer on growth and proline of the medicinal plant Pereskia bleo

There is strong observational evidence that climate change patterns impact the salinization of agricultural land in some countries. It suspected a significant increase soil salinity root zone occurs due to prolonged drought conditions. Rainfall Indonesia strongly influenced by EL NINO and LA NINA/Southern Oscillation (ENSO) events, global warming will cause ENSO events occur more frequently. Salinity provide adverse effects, such as plant growth, decreasing leaf water potential, morphological physiological changes, increased osmotic stress, changes biochemical processes. Potassium has role plants, including medium nutrient transportation, resistance drought, expanding enzyme activation. This study aims find out tolerance Pereskia bleo effect applying growth with proline indicators. The used Completely Randomized Design 2 factors (NaCl 0 ppm; 4 8 ppm/plant KCl g; 1.5 3 g/plant). results showed on there an interaction between potassium fertilizer proline. In general, application increases ability plants salinity.
