Abstract
Recirculating hydroponic systems, modifications of Cooper’s "nutrient film system" (NFT), have been successfully employed to grow stock plants for various macro- and micropropagation studies.
The influence of nitrogen levels on in vitro performance of tomato leaf explants was investigated and N, P and K effects on cutting production, rootability of cuttings and shoot production in vitro of willow (Salix spp.) stock plants were also studied.
Willow cutting number was enhanced by the highest N-P-K level, but rooting of cuttings and number of shoots produced in vitro were best with the medial level.
Successful inoculation of alder (Alnus) roots with the symbiotic N-fixing actinomycete, Frankia spp. was achieved, thus enabling propagation and Salix-Alnus interplanting research to be conducted.
These species and several others have been held in NFT, in some cases up to 2 years, with continuous function as stock plants for macro- and/or micropropagation.
