metal pollution has become one of the most serious environmental problems resulting from human activity. phytoremediation utilizes plants to uptake contaminants and can potentially be used to remediate metal-contaminated sites. the present study investigates heavy metal uptake (cd, cr, and ni) from soil by different organs of populus alba and morus alba. for this purpose, cd (40, 80, and 160 mg...

Türkiye-Gürcistan işbirliği kapsamında, ‘‘Gürcistan Kavakçılığını Geliştirme’’ projesi hazırlanarak, uygulamaya geçirilmiştir. Projenin ilk aşamasını oluşturan fidanlık denemeleri için Kavak ve Hızlı Gelişen Orman Ağaçları Araştırma Enstitüsü Müdürlüğü’ne ait klon bankasından 20 adet kavak klonu seçilmiştir. Kontrol olarak Gürcistan’ın doğal türleri (Populus alba Populus pyramidalis) kullanılmı...

The exotic shrub Lonicera tatarica (Tartarian honeysuckle) has aggressively invaded woodlands and forests in central and eastern North America; however, its impacts on native plant species are not well understood. We used a greenhouse seedling experiment to examine the effects of L. tatarica on Quercus alba (white oak), the presettlement dominant tree of many of these forests. Growthrelated par...

Poplar belongs to the family Salicaeceae, order Salicales and group Amentiflorae (Dickmann and Stuart, 1983; Eckenwalder, 1996). There are 35 species of poplar currently recognized in the world; out of those, 6 Populus species are indigenous to India– P. alba, P. ciliata, P. euphratica, P. gamblei, P. glauca and P. laurifolia, and during past many clones of exotic species of poplar (P. deltoide...

Microsatellite primers were developed and optimized for Lippia alba to characterize the L. alba germplasm bank of Universidade de São Paulo. A genomic library enabled the design of 9 microsatellite primers. Six of the 9 primers yielded polymorphic products, which defined 2 groups in the bank. The data provide support to characterize germplasm banks, genetic breeding programs for L. alba, and ot...

In order to investigate the effect of Ca on biomass allocation strategies tree species with different growth rates under drought conditions, we treated poplar (Populus canadensis cv) cuttings and mulberry (Morus alba) seedlings two soil moisture levels (40 ± 5% 80 maximum water holding capacity) (0 200 mg·kg−1 Ca2+) in a greenhouse experiment, then measured uptake, growth, gas exchange paramete...
