Phylogenetic diversity of rhizobial strains nodulating Robinia pseudoacacia L.

[Robinia pseudoacacia poisoning].

Identification of rhizobial strains nodulating Egyptian grain legumes.

Fifty four bacterial strains were isolated from root nodules of the grain legumes Cicer arietinum, Lens esculentus, Phaseolus vulgaris, Pisum sativum, and Vicia faba grown in cultivated lands of Beni-Suef Governorate (Egypt). Repetitive extragenic palindromic (REP)-polymerase chain reaction (PCR) clustered the strains into 15 REP-PCR groups. The nearly complete sequence of the 16S rRNA gene fro...

Black Locust (Robinia pseudoacacia L.) Root Cuttings: Diversity and Identity Revealed by SSR Genotyping: A Case Study

Background and Purpose: Black locust (Robinia pseudoacacia L.) is a valuable species native to North America and today widely planted throughout the world for biomass production. In Hungary, where Robinia has great importance in the forest management, the clones have been selected for plantations on good, medium and poor quality sites. To conserve the identity, superior clones are vegetatively ...

نگهداری بذر اقاقیا (Robinia pseudoacacia L.) در شرایط فراسرد

ذخیره‌سازی در شرایط فراسرد (196- درجة سانتی‌گراد) روشی جدید و بسیار کارامد برای نگهداری بلندمدت ژرم‌پلاسم گونه‌های گیاهی است. با استفاده از روش فراسرد می‌توان بذر، اندام‌های رویشی، سلول و دانة گرده گیاهان را برای بلندمدت نگهداری کرد. در شرایط فراسرد، فعالیت‌های متابولیکی سلول تقریباً متوقف می‌شود و طول مدت نگهداری به‌طور چشمگیری افزایش می‌یابد. بذر گونة جنگلی اقاقیا‌Robinia pseudoacacia...

Chemical composition and natural durability of juvenile and mature heartwood of Robinia pseudoacacia L.

The aim of this study was to characterize the properties of juvenile and mature heartwood of Robinia pseudoacacia L. (black locust). The content, the composition, and subcellular localization of heartwood extractives were studied in 14 old-grown trees from forest sites in Germany and Hungary, as well as in 16 younger trees of four clone types. Heartwood extractives (methanol and acetone extract...
