На примере молодых генеративных деревьев лиственницы сибирской исследован морфогенез однолетних ауксибластов. Показана коррелятивная связь характера чередования метамеров, интенсивности растяжения междоузлий, размера пазушных органов с диаметром сердцевины побега. Дана схема морфогенеза элементарного побега лиственницы сибирской.
Name in english: The structure of Larix sibirica (Pinaceae) auxiblasts
Abstract in english: The morphogenesis of 1-year auxiblasts (long shoots) was studied in young generative trees of Siberian larch (Tomsk). It was found that the longitudinal structure of auxiblasts is determined by a pattern of arrangement of leaves with and without an axillar bud on genetic spirak, which correlatively depends on pith diameter. Auxiblasts with wide pith have similar metamers gathered in longitudinal series. The series of leaves with buds reach the largest size in the medial part of the shoot and decline gradually towards the proximal and distal parts of the shoot. Changes in the series of leaves without buds are the reverse of those in the series of leaves with buds...
