| This paper deals with the mineral composition fresh and dry matter production of different organs of 4, 5 old guava (Psidium guajava L.) growth on sandy soil (Savanna) without fertilizer. The data obtained for fresh and dry matter productior are present in table 2 (in Portuguese). The concentration of the elements are presented in table 3 (in Portuguese). Finally, the total amounts of elements absorbed by guava are given in the following table: Element Plant (grams) Fruits (grams) Nitrogen (N) 42,55 20,4 Phosphorus (P) 3,84 2,3 Potassium (K) 52,01 31,3 Calcium (Ca) 47,81 0,2 Magnesium (Mg) 2,4 |

| This paper deals with the variation of the ascorbic acid content in Natal orange as related to the type of rootstock and to the picking time. The determinations were carried out in the juice of fruits which had practically the same ratio total solids/acidity being selected only the highest values of such quotient. The results can be summaryzed as follows: 1. The rootstock has a significant influence on the vitamin C content of the scion; this influence shows two interesting aspects: first, the ascorbic acid contet itself varies as a function of the rootstock; among the three rootstocks studied the highest values were obtained on scion growing on Serra d'água orange; the lowest values were found in "limão rugoso" and "limão francês" was intermediate; the... |
