Land system science (LSS) has substantially advanced understanding of land dynamics throughout the world. However, studies that explicitly address causative role culture in systems have been fairly limited relative to those examining other structural dimensions (e.g. markets, policies, climate). In this paper, we aim start a discussion on how better include LSS. Through four examples, show aspe...

the gf677 (prunus amygdalus×prunus persica) is a peach rootstock tolerant to fe deficiency .therefore, mass propagation of gf677 rootstock is recommended by bioreactor. on the other hand, plant micro-propagation using bioreactors can decrease the cost of production and makes it an economical method. in this research, the possibility of using bioreactor and optimization of the tissue culture pro...
