In vitro assimilate uptake and metabolism were evaluated in embryos of known age isolated from seeds at mid-podfilling through physiological maturity. The capacity of isolated Wye soybean embryos to take up exogenous [(14)C]sucrose dropped nearly 4-fold in less than 1 week at incipient cotyledon yellowing. This drop in rate of sucrose uptake coincided with cessation of seed growth as well as ra...

A disorder of sugarcane (Saccharum species hybrid) characterised by yellowing of the leaf midrib and lamina was first reported in East Africa in the 1960s. This disorder was termed yellow wilt (Ricaud, 1968). A similar disorder was reported as autumn decline in Brazil (Hughes, 1964). Some thirty years later similar symptoms were observed on sugarcane in Hawaii (Schenk et al., 1990) and Brazil (...

Unstabilised bisphenol A polycarbonate samples were aged under UV radiation for periods of up to 3000 hours. The samples were then characterised using FTIR/ATR, GPC, SEM, microscopy, light transmission and colour changes. The changes in optical properties were related back to the changes in the polymer microstructure and composition. In this study, the molecular weight of polycarbonate was seen...

Most commercial products of dehulled hemp seeds frequently include dark green remnants shells. The entire removal shell particles including seed coats and pericarp pieces can improve the quality hempseed-based products. In this study, structural characteristics fruit walls (pericarp) Cannabis sativa were examined using scanning electron microscopy. was comprised three distinct zones, exo-, meso...

To understand the metabolite dynamics and genetic regulatory mechanism of apricot shell, a typical endocarp, before after lignification are unknown, we investigated differences endocarp ‘Youyi,’ popular kernel-using cultivar, using ultra-performance liquid chromatography tandem mass spectrometry strategy. The thickness increased rapidly from 8 to 37 days flowering (DAF) lignin deposition began ...
