摘要

从紫花苜蓿(Medicago arborea L.)的根(60 h)和叶肉中分离到高产高产的原生质体,根的电镀效率较好,叶原生质体的电镀效率较好。建立了各种器官外植体诱导愈伤组织生长和植株再生的培养条件。通过分生器官发生,从组织和原生质体衍生的愈伤组织中获得可育植株。本文还讨论了紫花苜蓿属植物的种间杂交。

Regeneration of Medicago arborea L. plants from tissue and protoplast cultures of different organ origin

Remarkable yields of highly dividing protoplasts were isolated from rootlets (60-h-old) and mesophyll of Medicago arborea L. Plating efficiency was satisfactory for root and excellent for leaf protoplasts. Culture conditions were established for callus induction and growth from various organ explants and plant regeneration. Fertile plants were obtained from tissue and protoplast-derived calli through meristematic organogenesis. The results have been discussed in relation to somatic interspecific hybridization within the genus Medicago.
