Influencing Stock Production of Mojave Sage and Cape Daisy with the Application of Plant Growth Regulators

This study aimed to assess the effects of plant growth regulators (PGRs) on stock production mojave sage ( Salvia pachyphylla ) and ‘Avalanche’ cape daisy Osteospermum hybrid) that received foliar sprays following three PGRs: 200 400 ppm ethephon; 250 500 benzyladenine; 50 100 gibberellic acid 4 7 (GA 4+7 plus benzyladenine. Vegetative [height width index (GI)], number vegetative cuttings, fresh weight (FW) dry (DW) harvested cuttings data were collected. A propagation was conducted concurrently determine PGR treatments rooting cuttings. GA benzyladenine (50 ppm) increased both by ≥18% more than other treatments. The GI, FW, DW results showed similar trends across experiments 1 2 for each perennial. In study, percentage did not differ after weeks, indicating use in protocols could benefit producers perennials.
