Abstract

This work aims to study the effect of in vitro (tissue culture media ) and ex vitro (planting media) conditions on growth of some Araceae plants (Syngonium podophyllum, Spathiphyllum wallisii and Philodendron scandens) The obtained results indicated that MS basal medium at full salt strength supplemented with 30 g/l sucrose produced the highest shoot length, fresh weight and number of roots for Syngonium podophyllum. While MS at quarter salt strength supplemented with 10g/l sucrose was suitable to Spathiphyllum wallisii, which gave the highest shoot length and number of leaves. The best medium for root formation was MS basal medium supplemented with 10 g/l sucrose. For Philodendron scandens plants, the results pointed out that shoots cultured in MS at quarter salt strength with 30g/l sucrose gave the highest values of fresh weight, root length and number of roots.
For the effect of planting media, the data indicated that MS at full salt strength with 30g/l sucrose during rooting stage and planting mediumcontaining peat: sand at 3:1 (v/v) gave the highest survival percentage for Syngonium podophyllum plants.
The best growth and development of Spathiphyllum wallisii and Philodendron scandens plantsduring acclimatization stage were recorded for plantlets produced from MS at quarter salt strength with 10g/l or 20g/l sucrose during rooting stage and acclimatized in the previous planting medium (peat : sand 3:1 v/v), respectively.
