Hydrogel in the seedling growth of Eucalyptus dunnii Maiden under different irrigation management

This study evaluated the effect of using hydrogel in planting Eucalyptus dunnii seedlings pots, under different water-management regimens. Seedlings approximately 25 cm height were planted pots filled with 4.5 L soil. The experiment was Completely Randomized Design, a 2x3 factorial, absence and presence related to regimens (irrigation only planting, every 3 6 days). From until 47th day for symptoms water stress, chlorophyll content gas exchange. Finally, development plants root dry weights shoots, as well by determining retention curve. As result, use polymer yielded an increase delay drought consequently increasing levels. One can observe direct exchange this kind, where recovery variables analyzed 24 h after irrigation visible. Reviews biomass demonstrated that treatment showed best development. However, hydro retainer increased quality seedlings, besides being alternative method periods year.
