Website: http://www.rirdc.gov.au Published in November 2005 Printed on environmentally friendly paper by Canprint ii Foreword Durian (Durio zibethinus Linn.) and Mangosteen (Garcia mangostana Linn.) are known throughout SE Asia respectively as the King and Queen of tropical fruits. The durian is a tree native to the wet tropics of Peninsular Malaysia, Sumatra and Borneo and is now grown extensively through out SE Asia and northern Australia. The fruit is considered a delicacy and aphrodisiac by many dedicated consumers but is also renowned by some Europeans for its complex flavour and odour interactions. The mangosteen is a tree native to the wet tropics of Peninsular Malaysia, Sumatra and Borneo and is also grown extensively through out SE Asia and northern Australia. The fruit is highly esteemed and is favoured as a suitable antidote to the pungent durian. The durian and mangosteen industries are in their infancy in Australia with current plantings believed to be in the order of 11,000 and 15,000 trees respectively. The value of these industries is currently estimated to be $0.5M for durian and $0.75M for mangosteen, with industry projected values by 2010 of $12M and $6.0M respectively. These projections are based on current bearing and newly planted trees, the bearing capacity of mature trees and wholesale prices of $6.50/kg and $8.00/kg for fresh fruit. The industries lack basic agronomic information with many of the current management techniques used in Australia transferred from SE Asia. The industries representative body, Rambutan and Tropical Exotic growers Association (RTEGA), have a clear strategic plan and this project and its outcomes were developed to assist growers with basic information on leaf and soil standards suited to the north Queensland growing environment. This project was funded from RIRDC Core Funds (New Plant Products) which are provided by the Australian Government This report, an addition to RIRDC’s diverse range of over 1500 research publications, forms part of our New Plant products R&D program, which aims to facilitate the development of new industries based on plants or plant products that have commercial potential for Australia.

However, careful planning, preparation, and care of the trees are essential for success. This publication tells you what to consider before planting, how to plant your trees, and how to take care of them to ensure many seasons of enjoyment. Part 1: Planning Before Planting Fruit Selection Selecting the type of fruit to grow is the first step in tree fruit production. To begin, you need to know which tree fruit can be grown in North Carolina. Your region's climate determines the type of fruit you can grow successfully. The climate must be compatible with the growing requirements of the selected fruit crop. To take an extreme example, a tropical fruit such as the banana simply cannot survive in North Carolina. Bananas require a warmer climate and a longer growing season. Other tree fruit that may look promising in the glossy pages of mail order catalogs are also destined to fail if grown in incompatible climates. Climatic conditions vary greatly from one region to another in North Carolina, so make sure that the fruit you choose can grow successfully in your area. Table 1. Potential Tree Fruit Crops for North Carolina Fruit Location Varietal Considerations Management Most varieties will grow in North Apples Throughout North Carolina Moderate Carolina. Plant fire blight-resistant varieties Asian Pears Throughout North Carolina Moderate only.

  • Reliable Fruit Tree Varieties for Santa Cruz County

    Reliable Fruit Tree Varieties for Santa Cruz County

    for the Gardener Reliable Fruit Tree Varieties for Santa Cruz County lanting a fruit tree is, or at least should be, a considered act involving a well thought-out plan. In a sense, you “design” a tree, or by extension, an orchard—and as tempting as it may be to grab a shovel and start digging, the Plast thing you do is plant the tree. There are many elements to the plan for successful deciduous fruit tree growing. They include, but are not limited to – • Site selection • Sanitation, particularly on the orchard floor • Soil—assessment and improvement • Weed management • Scale and diversity of the planting • Pruning/training systems • What genera and species (apple, pear, plum, • Thinning peach, etc.) and what varieties grow well in an area • Pest and disease control • Pollination • Sourcing quality trees • Irrigation • The planting hole and process • A fertility plan and associated fertilizers • Harvest and post-harvest All of the above factors comprise the jigsaw puzzle or the Rubik’s Cube of fruit growing. In essence, you must align all the colored cubes to induce smiles on the faces of both growers and consumers. This article focuses on the selection of genera, species, and varieties that do well in Santa Cruz County, and discusses chill hour requirements as one major criterion for successful fruit tree growing. THE RELIABLE—AND NOT SO RELIABLE What Grows Well Here By “what grows well,” I mean what produces a reliable annual crop and is relatively disease and pest free. In Santa Cruz County, that includes— • Apples • Pluots • Pears

    Collection and Evaluation of Under-Utilized Tropical and Subtropical Fruit Tree Genetic Resources in Malaysia

    J]RCAS International Symposium Series No. 3: 27-38 Session 1-3 27 Collection and Evaluation of Under-Utilized Tropical and Subtropical Fruit Tree Genetic Resources in Malaysia WONG, Kai Choo' Abstract Fruit tree genetic resources in Malaysia consist of cultivated and wild species. The cul­ tivated fruit trees number more than 100 species of both indigenous and introduced species. Among these fruits, some are popular and are widely cultivated throughout the country while others are less known and grown in small localized areas. The latter are the under-utilized fruit species. Apart from these cultivated fruits, there is also in the Malaysian natural forest a diversity of wild fruit tree species which produce edible fruits but are relatively unknown and unutilized. Many of the under-utilized and unutilized fruit species are known to show economic potential. Collection and evaluation of some of these fruit tree genetic resources have been carried out. These materials are assessed for their potential as new fruit trees, as sources of rootstocks for grafting and also as sources of germplasm for breeding to improve the present cultivated fruit species. Some of these potential fruit tree species within the gen­ era Artocarpus, Baccaurea, Canarium, Dimocarpus, Dialium, Durio, Garcinia, Litsea, Mangif era, Nephelium, Sa/acca, and Syzygium are highlighted. Introduction Malaysian fruit tree genetic resources comprise both cultivated and wild species. There are more than 100 cultivated fruit species of both major and minor fruit crops. Each category includes indigenous as well as introduced species. The major cultivated fruit crops are well known and are commonly grown throughout the country.

The life history of A. rigidus on coconut and mangosteen was comparatively studied to understand the effects of host-plant species on its development, to investigate potential host-suitability factors that contributed to its outbreak infestation, and to gather baseline information on the development and characteristics of this pest. The study was conducted at the Institute of Plant Breeding, College of Agriculture and Food Science, University of the Philippines Los Baños. Insect size (body and scale) was not significantly different on both hosts during egg, crawler, white cap, pre-second and second instar stages, as well as during male pre-pupal, pupal and adult stages. The female third instars and adults, however, were bigger on mangosteen than on coconut. At the end of second instar, sexual differentiation was very visible wherein parthenogenic females further undergone two developmental stages: third instar and adults that feed permanently on the leaves. Males undergone three stages: pre- pupa, pupa and winged adults.
