| 摘 要： | 黑松(Pinus thunbergii Parl.)原产于日本,引入我国山东烟台沿海地区巳有70多年历史,生长优于当地的赤松(Pinus densiflora Sieb.et Zucc),抗松干蚧的能力高于赤松。解放后,黑松成为营造海防林的主要造林树种。在选材的黑松林内,约有90％以上的个体是黑松,另有不足10％个体的干形、皮色、树皮开裂、叶形、叶色、冬芽大小、颜色……等都不

| Abstract: | The pattern of isopreoxidase and isoestrase separated by gel electrophoresis were applied as "genetic marker" to study various forms collected from a P. thunbergii" plantation in Shandong province, which has been introduced for over 70 years and is near to a P. densiflora plantation.14 various isopreoxidase patterns have been found in 19 various forms of P. thunbergii, which show a combination of different degree and manner of both P. thunb and P. densif. A new form of P. thunb selected from those possesses a resistance to Matsucoccus matsumurae (Kwana) and Dendrolimus spectabilis Butter better than P. thunb. Its isopreoxidase pattern of the needles possesses complementary bands of both P.thunb and P.densif. Its isoestrase pattern of seeds is segregated into two parts:1/2 pattern of the new form and 1/2 pattern of P. thunb. All of these come to a conclusion that there are various forms of taxonomic hybrid of P. thunb and P. densif in the plantation.Key words:isozyme;various form;taxonomic hybrid;genetic marker |
