The kiwi is a fruit with maduration climatérica, which no evidence changes of appreciable external colour being the content of total soluble solids (SST) the index of maturity more used to determine the moment of the harvest. The content of dry matter (%MS) is highly related with the sensory quality, by what is desirable to have tools of handle that they promote his accumulation. The fosfitos (Fi) induce the synthesis of compounds of defence of the plants. It evaluated the effect of the application of Fi in a plantation of kiwi 'Hayward' on the indexes of maturity in the harvest and poscosecha and the tolerance of the fruit to the grey rot.
