Seedlings of aluminum (Al)-tolerant Citrus sinensis and Al-intolerant Citrus grandis were fertigated daily with nutrient solution containing 0 and 1.0 mM AlCl3●6H2O for 18 weeks. The Al-induced decreases of biomass and root total soluble proteins only occurred in C. grandis, demonstrating that C. sinensis had higher Al-tolerance than C. grandis. Under Al-treatment, C. sinensis roots secreted mo...

Environmental conditions and seedling quality interact to produce complex patterns of survival growth. Root growth potential (RGP) is one metric that can be rapidly measured prior planting, but the correlation RGP performance not consistent across studies. Site factors including microsite objects cast shade competing vegetation also influence performance. We examined effects RGP, presence/absen...

Aquilaria crassna Pierre ex Lec. and Tectona grandis Linn.f. are sources of resin-suffused agarwood and teak timber, respectively. This study investigated arbuscular mycorrhizal (AM) fungus community structure in roots and rhizosphere soils of A. crassna and T. grandis from plantations in Thailand to understand whether AM fungal communities present in roots and rhizosphere soils vary with host ...

The objective of this study was to investigate the effect of different cultivation regions on the pattern and content of flavonoids in two pummelo cultivars (C. grandis L. Osbeck) in China. Results showed that similar patterns of flavonoids were observed in the flavedo or juice of each pummelo cultivar from these cultivation regions, whereas the individual flavonoid content showed unique charac...

Grand fir (Abies grandis/Dougl. ex D. Don/Lindl.) represents the North American species that has potential to replace and complement some extent several commercial European species, in particular, Norway spruce silver fir. This is not only due its high production but also because of favorable effect on soil compared or pine. We tested sample trees from these tree growing same location for physi...

the brush-tailed mice of the genus calomyscus are distributed in the mountains of central asia and the middle east. the genus calomyscus represents five nominate species from iran (c. bailwardi, c. grandis, c. hotsoni, c. urartensis and c. elburzensis). in total 64 specimens from four species of calomyscus were studied for morphometric analyses the morphological differences among 10 populations...

The use of liquid instead of solid culture medium for the micropropagation of plants offers advantages such as better access to medium components and scalability through possible automation of the processes. The objective of this work was to compare a new temporary immersion bioreactor (TIB) to solid medium culture for the micropropagation of a selection of tree species micropropagated for comm...

The volumetric heating values of today's biofuels are too low to power energy-intensive aircraft, rockets, and missiles. Recently, pinene dimers were shown to have a volumetric heating value similar to that of the tactical fuel JP-10. To provide a sustainable source of pinene, we engineered Escherichia coli for pinene production. We combinatorially expressed three pinene synthases (PS) and thre...
