Even whith the advance in the techniques of seedlings production, many problems still remain to be solved, mainly thoseproblems related to seedlings delivery. This work verified the variability of the growth parameters in seedlings of Pinus elliottii indifferent positions inside the production tray, along the time, seeking to identify the best time and form of delivery of homogeneous andhigh quality seedlings. In order to achieve these purposes, an experiment was installed in the forest nursery of Santa Maria FederalUniversity RS. Ten evaluations of height, diameter of the collar and height/diameter relationship were performed, in intervals of 15days. It was simulated each tray of the repetition parcel in order to determine the best form of seedlings delivery from the green house.It was verified that, 135 days after germination, uniformity among morphologic parameters of seedlings delivery were achieved forthe simulations when dividing the tray in Border x Center (BxC), Right x Center x Left (DxCxE), and Quadrants, and that after 180days, Front x Center x Bottom (FrxCxF) standardization was achieved. Differences in the quality pattern of seedlings collected indifferent places and submitted to the same development condition were observed and that seedlings delivered on a regular scheduleallows obtaining homogeneous quality pattern. |
