| Objetivando avaliar os efeitos de diferentes combinações de NPK, com e sem calagem, sobre as características físicas e químicas do látex e as condições de explotação da seringueira (Hevea sp.), clone RRIM 600, foi conduzido um experimento em blocos casualizados com parcelas subdivididas contendo oito tratamentos: sem adubação e sem calagem (T1), sem adubação e com calagem (T2), N1P1K0 + calagem (T3), N2P2K0 + calagem (T4), N1P1K1 + calagem (T5), N2P2K1 + calagem (T6), N1P1K2 + calagem (T7) e N2P2K2 + calagem (T8). Nas duas subparcelas, foram utilizados os seguintes sistemas de explotação: (S1) ½S d/4 6 d/7 ET 2,5% LaPa 1/1 10/y e (S2) ½S d/6 6 d/7 ET 5,0% LaPa 1/1 10/y com quatro repetições. As doses utilizadas corresponderam a 0, 40 e 80 kg ha-1 ano-1 de... |

| A study on changes in net photosynthesis (Pn), transpiration (Tr), stomatal conductance (Gs) and photosynthesis water use efficiency (WUE) of cutted rubber branch c.v. RRIM 600. Four methods included, do not put into the water, immediately put the branch into the water after cut, and put into the water after cut 5 and 10 minutes. The comparing of Pn, Tr, Gs and WUE values before and after cut were done. The result were found that Pn, Tr and Gs decrease immediately after branch was cut. The value decreased rapidly in first 15 minutes. Putting the branch into the water immediately, and putting the brance into the water 5 or and 10 minutes after cut expressed that the Pn, Tr, Gs and WUE could restored to the normal value before the branch was cut.... |
