Abstract
This investagation ~ ~ caa r sr i e d out a t t h e experimental s t a t i o n of the Faculty of Agriculture, Tanta University a t Kafr El-Sheikh during 1973/1974 and 1974/1$175 seasozs, -D’..-.-u razta L;.s-Ult ~n%av~a rl, va rie~t?a Hibiscus .,,,, - --.-- -.Y - -rosa-s ixensi-- s and !@opomm E~~~UsXhrJu bs were used i n these experiments, These species are known among a l l gardeners as being important ornamenta 1 shrubs and i n the mean time are d i f f i c u l t s t o propagate by means of cv.ttings, This study was carried out t o f a c i l i t a t e t3is problem, extend the period of propagation and promoting good root system on higher percentage of t h e i r cuttings, The cu2tings fron each species were taken everyone and half month, a l l the year around, from November, 1, 1973 u n t i l the middle of September, 1975. These c u t t i n g s received a basal soak of aquous s o l u t i o n f rom eitha~in dole butyric a c i d ( I RA) or x-naphthalene a c e t i c acid (NAA) f o r 24 hours with concentrations, 50, 100 and 200 p.p.m. Thi~tys i x csttings from each s p e c i e s were used i n each treatmmt . The c u t t i n g s were planted i n pot0 of 20 cms, diameter. These cuLtings from each species were planted in each pst,. The pots were devided i n t o two grcups, kept i n p l a s t i c ho~se and outdoors, After thrae months from the date of p l a n t i n g cuttings, rooting percentage f o r every treatment , length, number, fxsh and dry weights of r o o t s per c u t t i n g were recorded f o r each species. C r i t e r i a f o r Aerial grmth was determined by included length, number, f r e s h and dry weights of branches f o r Duranta and Hibiscus. Height, f r e s h and dry weights of h a l l a e r i a l growth f o r iyoporum ~ir,t Total carbohydrates and nitrogen were determined i n the stem of cuttings before planting and the stems and leaves a f t e r t h r e e months of planting f o r rooted c u t t i n g s , Randomized comptele blook design with f a c t o r i a l s was used i n %he a n a l y s i s of t h e experiments.
