Abstract

The effects of a sugar mill effluent on respiration of rice (Oryza sativa L.c.v. Mushoori) seedlings have been investigated. Each experiment consisted of two parts, the effect of various concentrations of the effluent and the time-dependent changes induced by the undiluted effluent. A marked increase in the rate of respiration was noticed upon treatment with various concentrations of the effluent. The time-dependent changes in the respiratory rate were about threefold with the 12 hr of treatment, and thereafter a rapid loss was noticed. Additionally, the respiratory quotient was studied to elucidate the nature of the metabolism of seedlings as influenced by the effluent.

摘要

已对糖厂废水对水稻（Oryza sativa L.c.v. Mushoori）幼苗呼吸作用的影响进行了研究。每个实验包括两个部分，即不同浓度废水的影响以及未稀释废水引起的随时间变化的情况。用不同浓度的废水处理后，观察到呼吸速率显著增加。处理12小时后，呼吸速率随时间的变化约为三倍，此后则迅速下降。此外，还研究了呼吸商，以阐明受废水影响的幼苗代谢的性质。
