Abstract
Leachates and alcoholic extracts (10%) from potential hardwood cutting material were prepared from Pinus wallichiana,Cedrus deodara, Abies pindrow, Thuja orientalis, Aesculus indica, Rhododendron arboreum, Magnolia grandifolia and Quercus incana, that grow around Shimla -the mid Himalayas. Rooting response of standard hypocotyl cutting system (Cucumis sativus L. 8 day old cuttings that form, on average, 14 ischolar_mains by ninth day of suspension in water at 25 ± 1°C continuous light) to 10, 100 and 1000 times dilutions of original extract were recorded. Concentrated leachates from wood of all species were toxic while ischolar_maining was slightly prormoted at 1000 and 100 times dilutions of original extract. Alcoholic extracts were toxic even at 100 times dilutions while 1000 times dilutions slightly promoted ischolar_maining of standard hypocotyl ischolar_maining systems. Residue of alcoholic extract applied after dissolution in water promoted ischolar_maining at 1000,100 and 10 times dilutions as well.
