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...

l-Phenylalanine Ammonia-lyase Activity in Robinia pseudoacacia Seedlings: I. Cyclic Phenomenon Activity during Continuous Light.

Influences of light and darkness on l-phenylalanine ammonia-lyase activity of black locust (Robinia pseudoacacia) seedlings were studied. Light initiates both an increase in enzyme activity (or enzyme synthesis) and a subsequent decrease in activity. These dual influences of light create cyclic changes in l-phenylalanine ammonia lyase activity in continuous light. The cyclic changes in activity...

Evidence for inbreeding depression in the tree Robinia pseudoacacia L. (Fabaceae).

The magnitude of inbreeding depression within populations is important for the evolution and maintenance of mixed mating systems. However, data are sparse on the magnitude of inbreeding depression in Robinia pseudoacacia. In this study, we compared differences in the mature seed set per fruit, seed mass, germination success, and seedling growth between self- and cross-pollination treatments and...

The Silviculture of Black Locust (Robinia pseudoacacia L.) in Hungary: a Review

Black locust was introduced in Hungary between 1710 and 1720. The first large black locust forests were established at the beginning of the 18th century on the Great Hungarian Plain stabilizing the windblown sandy soil. In the country, black locust occupied 37.000 ha in 1885, 109.000 ha in 1911, 186.000 ha in 1938 and 415.000 ha in 2009. At present, it is the most widely planted species in Hung...
