Effects of different potassium chloride supplies on net photosynthetic rate (Pn), intercellular CO₂ concentration (C_i), transpiration rate (Tr) and stomatal conductance (Cond) in the leaves of <i>P. vulgaris</i>.

<p>Note: Each value is presented as the mean ± SE (n = 6). Values that are followed by a different letter in the same line are significantly different according to Duncan's multiple range test (<i>P</i><0.05). K0, K1, K2 and K3 indicate 0, 1.00, 6.00 and 40.00 mM KCl, respectively.</p

Effects of different potassium chloride concentrations on the contents of rosmarinic acid (RA), ursolic acid (UA), oleanolic acid (OA) and total flavonoids in the spicas of <i>P. vulgaris</i>.

<p>Note: Each value represents the mean ± SE (n = 3). Values that are followed by a different letter in the same line are significantly different according to Duncan's multiple range test (<i>P</i><0.05). K0, K1, K2 and K3 indicate 0, 1.00, 6.00 and 40.00 mM KCl, respectively.</p

Effects of different potassium chloride supplies on yields of rosmarinic acid (RA), ursolic acid (UA), oleanolic acid (OA) and total flavonoids in the spicas of <i>P. vulgaris</i>.

<p>Note: Each value is equal to the mean ± SE (n = 3). Values that are followed by a different letter in the same line are significantly different according to Duncan's multiple range test (<i>P</i><0.05). K0, K1, K2 and K3 indicate 0, 1.00, 6.00 and 40.00 mM KCl, respectively.</p

Effects of different potassium chloride supplies on foliar K, water and chlorophyll contents and growth parameters of <i>P. vulgaris</i>.

<p>Note: Each value represents the mean ± SE (n = 10). The values that are followed by the different letter in the same lines are significantly different according to Duncan's multiple range test (<i>P</i><0.05). K0, K1, K2 and K3 indicate 0, 1.00, 6.00 and 40.00 mM KCl, respectively.</p
