From: Response of potato (Solanum tuberosum L.) cultivars to drought stress under in vitro and field conditions

Fig. 2

Two-way hierarchal clusters associated with the morphological, physiological traits and tuber yield measured per plantlet/plant of combined data on 21 cultivars under different drought stress treatments in vitro and field conditions. Both in vitro and field experiments were conducted, and traits were recorded under drought conditions; 0.0, 0.1, 0.2 or 0.3 mol L−1 sorbitol for in vitro and 60%, 40% or 20% of moisture content for field studies. PFW plantlet fresh weight, SFW shoots fresh weight, RFW roots fresh weight, R/PFW roots/plantlet fresh weight, S/PFW shoots/plantlet fresh weight, RL root length, SAR surface area of root, NR no. of roots, NL no. of leaves, LAP leaf area/plantlet, PWC plantlet water content%, K+ potassium content in roots, SFW-F shoot fresh weight under field trial, SDW-F shoot dry weight under field trial, NT no. of tubers/plant, WT weight of tubers/plant
