Seed mass, seedling size and neotropical tree seedling establishment
1 We examined amongand within-species effects of seed mass for seedling establishment from seed to 5 years of age in a field experiment at Paracou, French Guiana. 2 Six seeds of each of eight species were weighed and planted into each of 120 plots (1 m 2 ) throughout closed-canopy forest along 12 100-m transects in 1998. 3 We described the microhabitat of each planting site using principal comp...
متن کاملVisualizing tephra deposits and sedimentary processes in the marine environment: The potential of X‐ray microtomography
Localized tephra deposition in marine sequences is the product of many complex primary and secondary depositional processes. These can significantly influence the potential applicability of tephra deposits as isochronous marker horizons and current techniques, used in isolation, may be insufficient to fully unravel these processes. Here we demonstrate the innovative application of X-ray microto...
متن کاملWRI1 is required for seed germination and seedling establishment.
Storage compound accumulation during seed development prepares the next generation of plants for survival. Therefore, processes involved in the regulation and synthesis of storage compound accumulation during seed development bear relevance to germination and seedling establishment. The wrinkled1 (wri1) mutant of Arabidopsis (Arabidopsis thaliana) is impaired in seed oil accumulation. The WRI1 ...
متن کاملEffect of Seed Storage Duration and Seedling Raising method on Chamomile Seedling Establishment
Objective: Chamomile is one of the commercial medicinal plants produced in Ethiopia. Besides, it is priority crop in national aromatic and medicinal plants research project in the country. As chamomile production affected by production techniques this activity was conducted to identify the effect of seed storage duration and seedling raising methods on its seedling establishmen...
متن کاملLunar cryptomaria: Mineralogy and composition of ancient volcanic deposits
Ancient lunar volcanic deposits, known as cryptomaria, have been detected by remote telescopic and orbital measurements since the 1970s. Cryptomaria are most easily identified by the presence of darkhalo impact craters and are associated with a mare basalt mineralogy, which is indicated by two pyroxene spectral absorption features near 1 μm and 2 μm in the visible to near-infrared (VNIR) wavele...
