Merchantable volume system for Populus x euramericana (Dode) Guinier cv. ‘I-214’ plantations in central and northern Spanish plateau

Responses of Populus deltoides × Populus nigra ( Populus × euramericana ) clone I - 214 to high zinc concentrations

• We hypothesized that poplar can be useful for the extraction of zinc (Zn) from contaminated soils and water. However, the physiological response and the base of tolerance of poplar plants to this heavy metal are little known. • Plants of Populus deltoides × P . nigra ( P. × euramericana ) I-214 clone were grown in glasshouse and treated with three different Zn concentrations (1, 100 and 1000 ...

Efficient Agrobacterium-Mediated Transformation and Analysis of Transgenic Plants in Hybrid Black Poplar (Populus × euromericana Dode Guinier)

Black poplar (Populus× euramericana Dode Guinier) is an industrially important tree with broad applications in wood and paper, biofuel and cellulose-based industries as well as plant breeding programs and soil phytoremediation approaches. Here, we have focused on development of direct shoot regeneration and Agrobacterium-mediated transformation protocols using the in vitro internodal stem tissu...

Development of a Compatible Taper Function and Stand-Level Merchantable Volume Model for Chinese Fir Plantations

Chinese fir (Cunninghamia lanceolata [Lamb.] Hook) is one of the most important plantation tree species in China with good timber quality and fast growth. It covers an area of 8.54 million hectare, which corresponds to 21% of the total plantation area and 32% of total plantation volume in China. With the increasing market demand, an accurate estimation and prediction of merchantable volume at t...

معرفی یک گونه جدید Melampsora روی Populus x euramericana در ایران NEW RECORD OF THE GENUS Melampsora ON Populus x euramericana FROM IRAN

اخیراً نمونه‌‌ای آلوده به زنگ روی Populus x euramericana جمع‌آوری شده از مازندران بررسی گردید که ویژگی‌هایی متفاوت از گونه‌های قبلا گزارش شده در کشور داشت. این نمونه دارای مراحل اوردینیوم و تلیوم بود. اوردینیوم‌ها که به دلیل جمع‌آوری آخر فصل غالبا توسط گونه‌ای هیفومیست هیپرپارازیت آلوده شده بودند به شکل سورهای کوچک، گرد و پراکنده با ظاهری پودری در سطح زیرین برگ‌های آلوده تشکیل ...
