There were four treatments:traditional cultivation during the wheat season + cultivation without fertilizationduring the rice season (CK1 field), traditional cultivation during the wheat season +traditional cultivation during the rice season (CK2 field), draining t...

abstract in order to study the effects of cultivation method and water quantities in drip irrigation on yield of potato, an experiment was carried out using a split plot based on randomized complete block design with 4 replications in torogh agricultural research station (mashhad, iran) for tow years (2001 and 2002). the main-plots were divided into 3 levels of irrigation: i1= 100, i2= 80 and i...

the fungus colletotrichum gloeosporioides is the causative agent of anthracnose disease of many tropical, subtropical and temperate fruits, and a microbial source of the anticancer drug, taxol. here, we introduce an optimized agrobacterium tumefaciens-mediated transformation (atmt) protocol for genetic manipulation of this fungus using hph and gfp-tagged hph genes as selection markers. results ...

We have developed a procedure for stepwise topographical control of network patterns and neurite connection directions between adjacent living neurons using an individual-cell-based on-chip multi-electrode array (MEA) cell cultivation system with an agarose microchamber (AMC) array. This procedure enables flexible and precise control of the cell positions and easy and flexible control of the pa...
