Fast economic development in China has resulted in a significant increase in energy demand. Coal accounts for 70% of China's primary energy consumption and its combustion has caused many environmental and health problems. Energy security and environmental protection requirements are the main drivers for renewable energy development in China. Small farmland and food security make bioenergy derived...
Biomass energy is the main energy source in rural China. The low per capita cropland in China makes it impractical to convert cropland to energy crop cultivation as in other countries; development of energy crops must not compete with food and other cash crops for prime cropland. Mulberry planted on marginal lands like land risers, land boundaries and waste slopelands in Ningnan County of China's...
A detailed description of male and female gametophytic development in Eriolaena candollei is presented to study the systematic affinities of Eriolaena within the Malvaceae s.l. Flowers are bisexual and tetramerous. Anthers are tetrasporangiate and cytokinesis in meiosis is simultaneous resulting mainly in tetrahedral tetrads. Anther wall development follows the dicotyledonous type and the tapetum...
Pedicularis is one of few genera for which pollination ecology has been studied extensively. Although over half of the species of Pedicularis are found in the mountains of southwestern China, pollination ecology has been studied there on a few species only. The present paper reports pollination ecology of Pedicularis rex subsp. lipskyana and P. rex subsp. rex from Sichuan, southwestern China. The...
