The aim of the research was to determine field, greenhouse and seed bed performance of plantlets derived from in vitro propagated plantlets of three potato cultivars. Generally, higher values were obtained from the mid-early maturing cultivar Marabel, compare to other cultivars (early cultivar Velox and and mid-early cultivar Concorde) for tuber yield, tuber number and average tuber weight. For...

Ascophyllum nodosum is the most important commercial seaweed. Seaweeds have been applied as soil conditioners in improving plant growth and development in agricultural crops. In current study and for the first time, extracts of brown seaweed A. nodosum improved the growth of Robinia pseudoacasia L., an ornamental tree. This research investigated the effect of cultivation beds (sand, perlite, co...

Seedlings, rooted cuttings from juvenile stock plants, and cotyledon-derived tissue culture plantlets were propagated from several coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) full-sib families so that the rooted cuttings and plantlets were clonally identical. The stock types (seedlings, rooted cuttings and plantlets) were planted in the field in spring 1987. In fall 1991, after f...

in vitro propagated and conventional runner propagated plantlets of strawberry (fragaria×ananassa duch) cv. ‘festival’ were transferred to the field and the size of crown for plants derived from both sources of planting material were compared. four sizes of the crown, i.e., < 0.5, 0.5-0.8, 0.8-1, and > 1 cm were taken from both sources of planting material. the results obtained flashed that veg...

Plant tissue culture refers to growing and multiplication of cells, tissues and organs of plants on defined solid or liquid media under aseptic and controlled environment. Micropropagation allows rapid production of high quality, disease-free and uniform planting material. The micropropagation of high quality planting materials of ornamentals, and forest and fruit trees has created new opportun...
