Testing a Plant Strengthening Agent in Horticulture

SUMMARY

In spring and summer 2010 three commercially available plant-strengthening agents (Myco-Sin (™), Alginure (™) und plantasalva (™)) were applied to three horticultural crops (spinach (Spinacia oleracea, Chenopodiaceae), pak choi „Tatsoi“ (Brassica rapa var. chinensis, Brassicaceae) and zinnia „Perserteppich“ (Zinnia angustifolia, Asteraceae)). The plot was arranged randomly in three replicates. Canopy parameters, quality and amount of yield and physiological parameters like chlorophyll content, nitrate- potassium- and ascorbate contents were measured. The trials health-status (pests, diseases) were monitored on open field. The effects were analyzed and shown in tables and graphs (Djufri, 2010). Foremost in the case of Planta salva a fertilization-effect is supposed. Trials will be carried on, modified and in more detail with an emphasis on the physiology of systemic resistance.
