Opis:
There is a rising demand for salt-tolerant species for landscaping. Purpletop vervain is an excellent landscape plant for gardens and parks, with fragrant lavender to rose-purple flowers. However, little is known concerning the effect of sodium chloride on morphological characteristics, flowering and mineral uptake of purpletop vervain. In this study, carried out in 2013–2014, the plants of purpletop vervain were grown in pots in an unheated plastic tunnel. The plants were watered with 200 mM NaCl solution four times, every seven days. Salinity-exposed plants were characterized by slightly reduced plant height, weight of the aboveground part and visual score. Salt stress caused also an increase in leaf content sodium, chlorine and manganese. Salinity had no effect on earliness of flowering and content in leaves of phosphorus, potassium, magnesium, copper, zinc and iron. Purpletop vervain seems to be plant species able to tolerate salt stress under controlled conditions.

Opis:
One of the limitations to using ornamental plants in green areas is too high salinity and alkalization of the soil. The adverse effect of salinity on plant growth and de-velopment may be effectively reduced by application of salicylic acid. Plectranthus ciliatus is an attractive bed plant with ornamental leaves, recommended for growing in containers, hanging baskets, or sunny borders. The aim of this study was to investi-gate the response of P. ciliatus to salicylic acid and calcium chloride. The plants were grown in pots in a glasshouse and were sprayed with solution of 0.5 mM salicylic acid and watered with 200 mM calcium chloride. The application of salicylic acid resulted in an increased weight of the aboveground parts, higher stomatal conductance and leaf greenness index and enhanced leaf content of nitrogen, potassium, iron and zinc. Salinity-exposed plants were characterized by reduced weight, stomatal conductance and leaf greenness index. Salt stress caused also a drop in leaf content of nitrogen, po-tassium and iron, and an increase in calcium, sodium, chlorine, copper and manganese concentration. Salicylic acid seemed to relieve salinity-mediated plant stress.
