摘要
[目的]为了揭示黄连木(Pistacia chinesis Bunge)叶芽发育进程,以便确定适宜的芽接时期。[方法]于2010年在河北农业大学标本园采集不同时期的黄连木叶芽,采用石蜡切片法,对其叶芽的发育进程进行了观察。[结果]黄连木叶芽的发育可分为叶芽原基出现期、鳞片发育期、雏叶形成期、维管束分化期、维管束形成期和叶芽原基发育期6个阶段。[结论]在5月10日以后黄连木叶芽已经基本发育完全,但新梢尚未完全木质化,5月20日以后,新梢逐渐木质化,可以进行芽接。
[Objective]The aim was to reveal the leaf bud development process so as to find suitable budding period of P.chinesis Bunge.[Method]There was studied in specimen garden of Agricultural University of Hebei in 2010 by collecting different development periods leaf buds with the method of conventional paraffin sectioning.[Results]The results showed that the development of P.chinesis Bunge leaf bud could be divided into 6 periods,which were leaf bud primordium period,squama formation period,rudimentary leaf formation period,vascular differentiation period,vascular formation period and leaf bud primordium development period.[Conclusion]Leaf bud developed completely on May 10th,but the shoots hadn't lignified completely;from May 20th,the shoots lignified gradually and the leaf bud was suited for budding.
