Tuyển tập các báo cáo nghiên cứu về lâm nghiệp được đăng trên tạp chí lâm nghiệp quốc tế đề tài:"Effect of article genotype and cutting type on the vegetative propagation of the pine hybrid (Pinus brutia (Ten) x Pinus halepensis (Mill). | 447 Ann Sci For 1994 51 447-454 Elsevier INRA Original article Effect Of genotype and cutting type on the vegetative propagation of the pine hybrid Pinus brutia Ten X Pinus halepensis Mill K Panetsos A Scaltsoyiannes p Alizoti Laboratory of Forest Genetics Department of Forestry and Natural Environment Aristotelian University of Thessaloniki 54006 Thessaloniki Greece Received 16 February 1993 accepted 12 April 1994 Summary Improved methods to propagate vegetatively selected individuals of the promising artificial pine hybrid Pinus brutia Ten X p halepensis Mill are required. Repeated spraying with 200 mg-N BA or one spraying with 1 000 mg-H of the herbicide Arsenal on the stems of 4-year-old seedlings resulted in the production of the largest possible number of fascicle shoots. The fascicle shoots produced were taken as cuttings and were tested for rooting. In the rooting experiments the effect of genotype cutting type cutting size and auxin treatment were investigated. Genotype and cutting type proved to be the most crucial factors for rooting and clones with high rootability. Pinus brutia Ten X p halepensis Mill induced fascicle shoot genotype effect rooting cutting vegetative propagation Resume L effet du genotype et du type de bouture sur la multiplication vegetative de I hybride de pin Pinus brutia Ten X Pinus halepensis Mill . L amelioration des methodes de multiplication vegetative des individus sélectionnés de I hybride artificiel de pin Pinus brutia Ten X Pinus hale-pensis Mill est nécessaire. Quatre differents régulateurs de croissance TIBA Alar GA3 BA ont été appliques avec differentes combinaisons et concentrations sur la tige de plants de 4 ans de cet hybride artlficielafin d obtenir I induction depousses interfasciculaires tableau I . L effet du meilleur trai-tement 200 mg-h1 BA de I experience a été compare avec celui de I herbicide Arsenal. La pulverisation répétée de 200 mg-F1 BA OU une pulverisation de woo mg-H d Arsenal sur la tige de plants de 4
