Morphologic plants evaluation of yam (Dioscorea spp.) from healthy tubers four and seven month’s elderly (Original)
Keywords:
clones; endogenous; morphologic; tubers, in vitro plantsAbstract
Starting from considering with originating from postures of healthy tubers plants in vitro during a first cultivation cycle in field, with good quality in under controlled conditions and established in a position to zeolite’s stonemasons right out in the sun, posteriorly these postures established in a right position to field in the sun, in distinct treatments. Four clones of the yam's cultivation, Guinea's Blanco (Dioscorea rotundata Poir), Caraqueño, white Criollo and Belep ( Dioscorea alata L.) were evaluated. They conformed four experimental variants according to the four clones. it was quantified to the 4 and 7 plantation months, to a total 50 plants population, they took at random 30 plants to which were determined the following variables: shoot length ( cm. ), Shoot diameter length ( cm. ), leaf lenght ( cm ), leaf width( cm ) systematically exploring the plagues incidence. As objectives of this investigation: evaluating the main morphologic indicators of endogenous clones’ plants ( Caraqueño, Creole Blanco ) and commercial seedlings obtained ( Belep, Guinea's Blanco ) from tuber healthy plants in the field to 4 and 7 plantation months.
