    Notes: Summary Iron supply influences the amount of manganese absorbed by plants. When it is low, increased manganese uptake and translocation occurs. However, with excessive iron supply an increase in manganese uptake results, but not in its translocation. Manganese uptake is diminished under conditions of very low iron availability.

    Notes: Abstract In recently pruned olive logs, an increase in ethylene release has been observed between 48 and 72 hr after pruning. The values reached, as well as the duration of ethylene release, varied greatly from one log to another. PioneerPhloeotribus scarabaeoides females have shown a preference for logs in which ethylene emission was higher. In logs treated with ethrel, a significant increase in ethylene emission was observed, together with a greater period of release. Therefore, the use of logs treated with ethrel could be of great importance in the control of this pest of olive trees.
