Abstract

A seaweed/humus extract (ROOTS) was tested as a propagation biostimulant. Transplants from seed showed enhanced root, root hair, and shoot growth. Cultivars tested included: Broccoli `Bonaza', Coleus `Park's Bril1iant', Dahlia `Redskin', Eggplant `Early Bird', Gazania `Pinata', Geranium `Earliana' and `Hybrid Orbit', Impatiens `Shady Lady' and New Guinea `Tango', Marigolds `Gay Ladies' and `Climax', Nicotiana `Nikki', Pepper `Park's Whopper', Petunia `Total Madness', and Tomatoes `Sweet Million', `Good n Early', `Better Boy', `Early Girl', `Lady Luck' and `Super Steak'. Cuttings from citrus cultivars showed improved rooting (Lemon `Ponderosa', Lime `Bearss', and Orange `Calamondin'). Cuttings from succulents also showed improved propagation ( Pedilanthus tithymaloides cucullatus, Senecio deflersii , and an unknown stapeliad species). Seaweed extracts, known growth stimulants, when fortified with humic acid, offer promise as a propagation biostimulant.
