| Abstract | ||
| This study was conducted at the lath house of Nineva Horticulture station/ Mosul-Iraq throughout 2004 seasons. The aim was to study the effect of the stratification periods of 0, 60, 90 and 120 days at (5 ± 1°c) on three cultivators of hazelnut seeds Corylus avellana, ُُEmadia local type, Barcelona and Kenttish cob hazelnut which had been soaked in three concentrations of Gibberellic acid at zero, 250 and 500 mg.lit-1 respectively, to improve and increase the average of subsequently seedlings growth. The seeds had been planted at the beginning of March 2004.The results asserted that the increased stratification periods and the soaking of the seeds in Gibberellic acid have significant effect on their subsequently seedling growth.The study also revealed that there has been a clear-cut difference as regard to the response of the cultivators of the hazelnuts under study and as follows: Barcelona seeds was soaked in 500 mg.lit-1 GA3 and stratified for 90 days had recorded the hightest average of seedling leaf area , dry vegetative weight and the average of the main root lentgh , 1050.0 cm2/seedling ,22.60 gram / seedling and 26.85 cm., respectively .Barcelona seeds stratified for 120 days and soaked in to 250 mg.lit-1 (GA3) had given the highest of mean vegetative fresh weight of 38.20 gm/seedling.The highest average of the fresh vegetative weight and the dry weight of roots, 46.55 gm. and 21.25 gm. respectively had been of Barcelona cultivator grown out of the seeds which stratified at 90 days and soaked at 250 mg.lit-1 (GA3). | ||
