Growth and Reproductive Phenology of Welwitschia Mirabilis Hook. F
Reproductive phenology, reproductive traits and the pre emergent reproductive success (PERS) of Welwitschia mirabilis were studied in plants growing in the Botanical Garden of Portici. The leaves grow throughout the year and growth is positively correlated to temperature and day length; at flowering, the growth rate slows down. The plants have a reproductive cycle lasting 9-10 months; male plan...
متن کاملHigh levels of genetic variation exist in Aspergillus niger populations infecting Welwitschia mirabilis hook.
Aspergillus niger is an asexual, haploid fungus which infects the seeds of Namibia's national plant, Welwitschia mirabilis, severely affecting plant viability. We used 31 randomly amplified polymorphic DNA markers to assess genetic variation among 89 A. niger isolates collected from three W. mirabilis populations in the Namib Desert. While all isolates belonged to the same vegetative compatibil...
متن کاملFabrication of Ti3SiC2-SiC max phase composites via in-situ and ex-situ synthesis
Recently, a series of three-component compounds with the combination of Mn+1AXn known as Max phases have been considered as a new material. One of the most important features of Max phases, is the self-healing property of them. The main reason for considering Max Phases is a unique collection of unusual properties including their metallic, ceramic, physical, and mechanical properties. One of th...
متن کاملIntegrating Ex situ and In situ Conservation of Lemurs
Site-based and cross-regional habitat and species conservation e!orts in Madagascar, such as proposed in the previous chapters of this Lemur Conservation Strategy, should always be the main focus of lemur conservation. However, with many wild lemur populations rapidly declining and their habitat being lost at constantly high rates, captive assurance colonies are becoming increasingly important,...
متن کامل“The Ex Situ Conservation of Stinking Cedar”
The propagation of plants for food, timber, medicines and aesthetics has been a principal activity of man for millennia. However, the systematic propagation of plant material for the purposes of conservation has a recent history, probably dating back only a few decades. The propagation and distribution of Torreya taxifolia from wild collected, documented material is one of the largest projects ...
