The advent of next-generation sequencing has facilitated large-scale discovery, validation and assessment of genetic markers for high density genotyping. The present study was undertaken to identify markers in genes supposedly related to wood property traits in three Eucalyptus species. Ninety four genes involved in xylogenesis were selected for hybridization probe based nuclear genomic DNA tar...
Seedlings of aluminum-tolerant 'Xuegan' (Citrus sinensis) and Al-intolerant 'sour pummelo' (Citrus grandis) were fertigated for 18 weeks with nutrient solution containing 0 and 1.2 mM AlCl₃·6H₂O. Al toxicity-induced inhibition of photosynthesis and the decrease of total soluble protein only occurred in C. grandis leaves, demonstrating that C. sinensis had higher Al tolerance than C. grandis. Us...
Tectona grandis (teak) and Vernonia amygdalina (bitter leaf) are plants used in traditional medicine in West Africa. In this study, we tested ethanolic and hydro-ethanolic extracts of bark and leaves of T. grandis and ethanolic extract of leaves of V. amygdalina for their inhibitory effect on Toxoplasma gondii, a protozoan parasite responsible for toxoplasmosis. Ethanolic extract of V. amygdali...
The independent evolution of heteromorphic sex chromosomes in 19 species from 4 families of flowering plants permits studying X/Y divergence after the initial recombination suppression. Here, we document autosome/Y divergence in the tropical Cucurbitaceae Coccinia grandis, which is ca. 3 myr old. Karyotyping and C-value measurements show that the C. grandis Y chromosome has twice the size of an...
Plectranthus is a genus which includes species of ornamental and medicinal potential. It faces taxonomic problems due to aggregating species previously belonging to the genus Coleus, a fact that has contributed to the existence of various synonymies. The species Plectranthus amboinicus, Plectranthus barbatus, Plectranthus grandis and Plectranthus neochilus are included in this context. Some aut...
بازدارندگی تخمریزی اسانس چهار گونه اکالیپتوس شامل eucalyptus sargentii maiden، e. camaldulensis dehn، e. grandis hill et. maiden وe. viminalis labill روی این آفت بررسی شد. این آزمایش در قالب طرح کاملاً تصادفی در پنج تکرار انجام شد. اسانسهای گیاهی با روش تقطیر با آب تهیه شدند. آزمایش در شرایط دمایی 2±30 درجه ی سلسیوس و رطوبت نسبی 5±60 درصد و در تاریکی انجام شد. نتایج نشان داد که هر چهار اسانس...
A new species of caligid copepod (Siphonostomatoida), Anuretes grandis sp. n., parasitic on the painted sweetlips [Diagramma pictum (Thunberg)] in Taiwan is described. The new species is distinguished from its congeners by having: (1) free margin of cephalothorax not covering fourth pediger, (2) large genital complex longer than 2/3 of the cephalic shield, (3) no maxillary whip, (4) leg 3 with ...
Remote sensing is viewed as a cost-effective alternative to intensive field surveys in assessing site factors that affect growth of Eucalyptus grandis over broad areas. The objective of this study was to assess the utility of hyperspectral remote sensing to discriminate between site qualities in E. grandis plantation in KwaZulu-Natal, South Africa. The relationships between physiology-based hyp...
تاثیر حشره کشهای رایج در کنترل سن گندم eurygaster integriceps ، فنیتروتیون و دلتامترین ، بر روی زنبورهای پارازیتوئید trissolcus grandis و t.semistriatus مطالعه شد.
