Germination promotion of rhazya stricta decne

ABSTRACT

Rhazya stricta Decne is a medicinally important plant of sub-montane tracts in Pakistan. Laboratory studies revealed that non-treated seeds had 66%, 64% and 40% germination after 25 days incubation at 20 °C, 25 °C, and 30 °C respectively. Mechanically scarified seeds treated with 0.50 ppm GA3 and IAA gave 90% and 70% germination at 25 °C after 14 days. Mechanical scarification followed by 1- and 2-minutes treatment with acetone gave 78-80% germination at 20 °C and 65-70% at 25% on the 16 th day
