diameter is when to do the grafting, using grafting wood from near the top of the tree that you wish to propagate from. THERE has been a bountiful supply of mangoes, both in Palm Beach and Dade counties this season. The fruit is of a superior quality and for table use, when properly prepared, is superior to the peach. The newer varieties are yet scarce and high in price, as there are comparatively few trees in these counties that have reached the bearing age. Among the new varieties which have proven to be superior fruit and fibreless, are the Sundersha, Mulgoba, Bennett, Cecil Rajapouri, Amini and others. The Su …

3 HOTEL AVILA CARACAS VENEZUELA CARTER L. GARDNER MANAGER Mangos. Advances in vegetative propagation and in the development of profitable commercial varieties have been notable, though we still have a lot to do, probably, in connection with this last point. Haden is not doing too badly as yet in the tropics. I want to mention Mulgoba and Pairi and Amini and Sandersha of the Indian group, and Cambodiana and the Filipino or Manila seedlings of what I still like to call the Philippine group, though some folks don't agree with me. And the newer Florida varieties. And Julie. Avocados. Good work has been done on grafti …

and the seedling fruit has been carefully inspected by propagators, the best selected and budded, grafted or inarched, and a few energetic planters now have trees in bearing. George B. Cellou, of Miami, has been greatly interested in growing the finer strains of tropical fruits, has spent lots of money in procuring the best, and now has the only purely tropical nursery in the world. John B. Beach, of West Palm Beach, has also taken a great interest in introducing the budded varieties of this fruit. The Pollock, which originated at Miami, has been considered one of the finest varieties, and has been budded extensi …

Guava, 2. propagation by cuttings and by conventional methods of grafting are not practical, but modern techniques have solved the problem to a highly satisfactory degree. Veneer grafting, using as rootstocks young plants in vigorous growth, and covering the grafts with strips of polyethylene plastic, gives excellent results. The Cattley or strawberry guava is considerably more frost-resistant and is popular in many subtropical regions. It is a large shrub, attractive for its thick glossy-green oval leaves and its white flowers. The fruits are round, occasionally as much as two inches in diameter, and contain num …

grafting, when the young shoot is about 10" high. This last one gives good plants and in a shorter time. We have had excellent results with this method. The number of grafted plants which are sold yearly may be estimated in about 60 to 70,000. As soon as the plant is well developed in the nursery, it is dug out, with as much soil as possible, and planted into bamboo baskets; then, they are kept under lathhouses, where they are watered daily, as long as it doesn't rain. As soon as the plant shows the start of new vegetation and good rooting, it is sold. When planted in the grove, we recommend the shading during th …

This classification is of interest as showing the range of surface characteristics, but horticulturists have never paid much attention to it when selecting seedlings for vegetative propagation. Safford considered that a certain degree of correlation existed between these forms and flavor and quality of fruit. It appears that the few named varieties which are grown today in Australia, in California, in Spain and perhaps one or two other regions have been selected for quality more than any other factor, though size of fruit, appearance, and most of all productiveness, have sometimes been gi …

very large one. It is in its third year so by next season it will most likely fruit a lot. This particular tree was bought by me for three dollars and fifty cents in Honolulu! It attracted my attention because it was such a large and beautiful fruit I asked the grower to graft one of it and he charged me $3.50. I bought another tree or rather plant which gave smaller fruits, but it died without any fruit. Say Mr. Degener, can you in some way get me scionwood for grafting of the varieties MacDonald, Whitney, Beardslee, Holey and the Tower? They are all of the Guatemalan Avocado and winter fruiting which is very im …

we were out for new and rare things, such as the feijoa, the cherimoya, the white sapote, and above all the avocado. California was just commencing to grow this last-named fruit; there were a few seedling trees scattered here and there from Santa Barbara southward, and nurserymen were beginning to propagate them by grafting and to offer them for commercial cultivation. Some of these avocados were good varieties - or so they seemed to their sponsors. I secured the countryside, looking for the best ones, and arranging with their owners to give us propagating rights.

around Guimar there are occasional groups of five to 10 trees, planted to produce fruit for the market. Not much of an industry. And near this two are the only two plantings of grafted trees, in orchard form, which we saw - and we assume we saw everything as we were in the hands of our friend Ing. Garcia Cabezón who is doing all he can to encourage avocado cultivation in the Canaries. The development of grafted varieties has been one of the many services of the Jardin de Aclimatación de Orotava. It was commended by don Juan Bolinaga, a horticulturist from northern Spain who was in charge of this garden for about …

value it is quite ornamental, and possesses the characteristic of being extremely drought-resistant, thus making it valuable for planting in arid countries. The fruits resemble in appearance an apple or a quince, and good specimens are from three to four inches in diameter. The flesh is whitish or creamy yellow, and contains three to five large seeds, very much like orange seeds on a larger scale. It is soft and melting when fully ripe, and of a flavor difficult to describe, but liked by almost everyone, and sometimes said to resemble that of the peach; it lacks, however, any trace of acidity or spiciness. When g …

6. the sooner they are planted after removal from the fruit, the better. Large seedlings are difficult to transplant from the open ground, hence plants should be potted while still small and moved from time to time into larger containers until they are a year old. They are then ready for grafting, or for trans- planting to the field. Planting and Care Guava trees are often set too closely together for best production. If the soil is fertile they should be spaced about 20 feet apart, each way. Preparation of the land should be the same as for orange trees. Grafted guavas are usually set in the field about a year f …

15. should not be extremely high - heat, bright light and low humidity result in the fruit becoming "sunburned." A rather heavy soil is considered best for loquats, but the tree has been grown successfully on many other types; light sandy ones (which will required plenty of irrigation during dry periods) and even stiff clays, if well drained. The volcanic sandy/and clay loams so abundant all down the Pacific side of tropical America have proved excellent. Propagation There is no excuse for planting seedling loquats, unless one wishes to grow a large number and select out the best for vegetative propagation. It is …

GARDNER MANAGER What progress have we made in the use of vegetative propagation, in the establishment and propagation of superior chance seedlings (and of course the varieties produced by the plant breeders); in improved cul- tural practices; and so on. I would like to discuss some of these points in relation to those tropical fruits which seem to be the most important or the most interesting at the present day and remember that when I say "we have done this or that" I am talking about all those horticul- turists, from way back yonder down to the present time, who have de …

… ep a close vigil Amelonado seedlings were planted every tenth plant, and when the virologist made his periodic inspections these plants as well as the clonal plants were carefully observed for symptoms. CULTURAL PRACTICES Cultural requirements of tropical crops are almost as varied as the crops themselves, so it is impossible to make general recommendations. As mentioned previously, publications and word of mouth advice can be of assistance but regardless of the source, adaptations will be required to fit the local situation. Many special procedures can be adapted to assist in growing a crop. For example, we have

TROPICAL FRUIT PROGRAM FOR THE MONTGOMERY FOUNDATION The Fairchild Tropical Garden is internationally useful, and has gained great prestige, in the field of ornamental horticulture. The Montgomery Foundation should round out the program by developing and maintaining a collection of tropical fruits, especially those of major importance. The Montgomery Foundation has better land for this purpose than either Chapman Field or the Subtropical Experiment Station at Homestead and will not be handicapped by changes in policy and financial support, as are government institutions. The Foundation is prepared to introduce fr …

This situation is changing, and one of the major purposes of this book is to assist nurserymen regarding best methods of propagation, the choice of varieties of each fruit and the exercise of great care in labelling. As regards commercial fruits, it must be remembered that new varieties come onto the market from time to time. This is especially true of fruits which are relatively new, so far as commercial cultivation is concerned. The planter should pay utmost attention to this subject before he lays out his orchard.
