Laboratory of Plant Environmental Resources, Department of Agronomy, Faculty of Agriculture, University of Brawjaya, Malang 65145, East Java, Indonesia Received: December 18, 2012 / Published: March 20, 2013. Abstract: Temperature is the major factor limiting the cultivation of apple (Malus sylvestris Mill), a subtropical species, in the tropics. This fruit crop, successfully cultivated at high altitudes in the region of Malang (East Java, Indonesia), showed a decline in productivity (fruit yield and quality) in the last decade. A series of studies were conducted in the production centre of apple in the region of Malang to investigate several environmental factors evoking the decrease in the productivity of apple trees (cv. Manalagi) in 2008-2009. The present paper was focused on the analysis of air temperature as a limiting factor of the productivity of apple trees. Data of apple productivity were recorded at the first harvest of 36 apple orchards of 9-35 years old selected randomly that covered the whole range of orchard altitudes (861-1,434 m) in the study area. Air temperature and relative humidity during the day (0.06, 12.00 and 18.00n h) were recorded at the orchard locations. The air temperature, closely related to the altitude, declined at a rate of 0.679 °C 100 m-1 of altitude close to a wet lapse rate.

  • Malus Sylvestris
    The Ecology and Genetics of Scotland’s Native Wild Apple: Malus sylvestris Rick Worrell, Markus Ruhsam, James Renny, Will Jessop and Graeme Findlay Supported by Scottish Forestry Trust, Sustainable Forestry SCIO, Patsy Wood Trust, Forest Enterprise Scotland 2018 Summary This project provides the first account of the ecology and genetics of wild apple (Malus sylvestris), which is probably Scotland’s least understood and most under-appreciated native tree. Commonly known as crab apple, it is familiar to people as a small tree planted in hedgerows; and on this basis foresters and ecologist appear to have dismissed it as unimportant. In fact it is a characterful and ecologically important native tree, occurring in semi-natural woodland and wood pasture across most of Scotland. Wild apple is a progenitor of the domestic (eating) apple – this being a hybrid between a sweet apple from eastern Asia and both European and Asian wild (crab) apples, estimated to have arisen 1500-4500 years ago. Different apple species hybridise easily, and in recent centuries widespread planting of domestic apples in Europe has led to these hybridizing with wild apples; and recent DNA studies show that between 7-36% of apparent wild apples in various European countries are in fact hybrids. This project investigated the situation in Scotland and northern England by comparing DNA markers in 342 wild-grown apples; and showed that 27% of apparent wild apples are in fact hybrids between wild and domestic apple. However, in several parts of Scotland there are substantial populations of more or less pure wild apple; these occurring where there is a high incidence of semi-natural woodland, for example in Loch Lomond and the Trossachs, Galloway, Highland Perthshire and the Lake District.

Corresponding Author: Sestry Misfadhila ABSTRACT become mushy for applesauce. Apples are also made into apple cider drinks. [1] Apples are the edible fruit produced by the apple tree Malus domestica. The apple tree is cultivated worldwide and is the most widely grown species in the genus Malus. The apple tree originates from Central Asia. Apple has been developed for thousands of years in Asia and Europe and brought to North America by European colonizers. Apple has a high nutritional value so that it can be a good food source. Humans widely consume an apple. Different cultivars are bred for a variety of flavors and uses, including cooking, eating raw, and juice production. Phytochemically, apples are reported to contain triterpenoids, flavonoids, organic acids, and sterols. Pharmacologically, this fruit is reported to have Antioxidants, Figure 1: Fruit of Apple.

  • Nutrition Comparison Between Genus of Apple (Malus Sylvestris and Malus Domestica) to Show Which Cultivar Is Best for the Province of Balochistan
    Journal of Asian Scientific Research, 2013, 3(4):417-424 Journal of Asian Scientific Research journal homepage: http://aessweb.com/journal-detail.php?id=5003 NUTRITION COMPARISON BETWEEN GENUS OF APPLE (MALUS SYLVESTRIS AND MALUS DOMESTICA) TO SHOW WHICH CULTIVAR IS BEST FOR THE PROVINCE OF BALOCHISTAN Muhammad Aziz Department of Chemistry University of Balochistan M. Anwar Institute of Biochemistry University of Balochistan Zaheer Uddin PCSIR Laboratories, Quetta Hiba Amanat PCSIR Laboratories, Quetta Huma Ayub PCSIR Laboratories, Quetta Saima Jadoon University of Kurdistan, Hewler, Iraq ABSTRACT Apple farming cultivation is expanding in Balochistan. But there is no scientific study present on this subject which apple genus is beneficial according to nutritional point of view. This is the main object of this study to evaluate the nutritive composition of different Genus of apples. Keeping this objective in mind two different genus of apples were selected i.e. Malus Sylvestris and Malusdomestica. To know the percentage composition of Moisture, Ash, Brix, Fat, Pectin, Fiber, Protein, Total sugar, Calcium, Sodium, Potassium, Phosphorus, Magnesium, Iron, Fat and water soluble vitamins in apples, they have been quantitatively analyzed using Atomic Absorption Spectroscopy, Flame Photometry and other chemical methods. The nutritional assessment results show that Malusdomestica (Discovery) has an edge over Malus sylvestris (Red Sentine). The percentage of Moisture, Potassium and Ascorbic acid is slightly high in Malus Sylverstris, On the other hand the Ash, Brix, Fat, Pectin, Fiber, Protein and Total sugar percentages are comparatively high in Malusdomestica and show a difference 0.15, 3.9, 0.48, 0.4, 5.5, 0.25, 8.25 of percentages respectively.

  • Dihydrochalcones in Malus Mill. Germplasm and Hybrid
    DIHYDROCHALCONES IN MALUS MILL. GERMPLASM AND HYBRID POPULATIONS A Dissertation Presented to the Faculty of the Graduate School of Cornell University In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Benjamin Leo Gutierrez December 2017 © 2017 Benjamin Leo Gutierrez DIHYDROCHALCONES IN MALUS MILL. GERMPLASM AND HYBRID POPULATIONS Benjamin Leo Gutierrez, Ph.D. Cornell University 2017 Dihydrochalcones are abundant in Malus Mill. species, including the cultivated apple (M. ×domestica Borkh.). Phloridzin, the primary dihydrochalcone in Malus species, has beneficial nutritional qualities, including antioxidant, anti-cancer, and anti-diabetic properties. As such, phloridzin could be a target for improvement of nutritional quality in new apple cultivars. In addition to phloridzin, a few rare Malus species produce trilobatin or sieboldin in place of phloridzin and hybridization can lead to combinations of phloridzin, trilobatin, or sieboldin in interspecific apple progenies. Trilobatin and sieboldin also have unique chemical properties that make them desirable targets for apple breeding, including high antioxidant activity, anti- inflammatory, anti-diabetic properties, and a high sweetness intensity. We studied the variation of phloridzin, sieboldin, and trilobatin content in leaves of 377 accessions from the USDA National Plant Germplasm System (NPGS) Malus collection in Geneva, NY over three seasons and identified valuable genetic resources for breeding and researching dihydrochalcones. From these resources, five apple hybrid populations were developed to determine the genetic basis of dihydrochalcone variation. Phloridzin, sieboldin, and trilobatin appear to follow segregation patterns for three independent genes and significant trait-marker associations were identified using genetic data from genotyping-by-sequencing. Dihydrochalcones are at much lower quantities in mature apple fruit compared with vegetative tissues.

  • Southern Garden History Plant Lists
    Southern Plant Lists Southern Garden History Society A Joint Project With The Colonial Williamsburg Foundation September 2000 1 INTRODUCTION Plants are the major component of any garden, and it is paramount to understanding the history of gardens and gardening to know the history of plants. For those interested in the garden history of the American south, the provenance of plants in our gardens is a continuing challenge. A number of years ago the Southern Garden History Society set out to create a ‘southern plant list’ featuring the dates of introduction of plants into horticulture in the South. This proved to be a daunting task, as the date of introduction of a plant into gardens along the eastern seaboard of the Middle Atlantic States was different than the date of introduction along the Gulf Coast, or the Southern Highlands. To complicate maters, a plant native to the Mississippi River valley might be brought in to a New Orleans gardens many years before it found its way into a Virginia garden. A more logical project seemed to be to assemble a broad array plant lists, with lists from each geographic region and across the spectrum of time. The project’s purpose is to bring together in one place a base of information, a data base, if you will, that will allow those interested in old gardens to determine the plants available and popular in the different regions at certain times. This manual is the fruition of a joint undertaking between the Southern Garden History Society and the Colonial Williamsburg Foundation. In choosing lists to be included, I have been rather ruthless in expecting that the lists be specific to a place and a time.

  • Leaf Peroxidase Isozyme Polymorphism of Wild Apple
    Agronomy Research 6(2), 531–541, 2008 Leaf peroxidase isozyme polymorphism of wild apple R. Petrokas1 and V. Stanys2 1 Department of Genetics and Breeding, Lithuanian Forest Research Institute, Liepų 1, LT- 53101 Girionys, Kaunas distr., Lithuania; e-mail: [email protected] 2 Department of Genetics and Biotechnology of Orchard Plants, Lithuanian Institute of Horticulture, LT-54333, Babtai, Kaunas distr., Lithuania Abstract. The main aims of the study were to reveal the isozyme resemblances in the leaf peroxidase of wild apple and to define the traits related to the identification of Malus sylvestris Mill. The results of the study are based on leaf isozyme analysis of seven progenies selected according to the specific features of mother trees at their natural sites from the mixed forests of south-western and central Lithuania. The patterns of peroxidase isozymes were obtained by electrophoresis. The presence or absence of isoforms has been applied to compare peroxidase patterns of progenies. Species-specific peroxidase markers of Malus sylvestris Mill. were found. The progenies of crab apple trees had the higher proportion of identical siblings in comparison to the progenies of non-crab apple trees; autogamy or even apomixis might be the factor in wild apple if considering the resemblance of some siblings in the progenies confirmed by the simultaneous comparison of their peroxidase isozyme patterns. The phenotypic characterization of rapidly growing reproductive structures (e.g. fruit characters) may be useful for the identification of Malus sylvestris Mill. independent of the remaining characters of wild apple trees. Key words: isozyme resemblances, leaf peroxidase, Malus sylvestris Mill., phenotype INTRODUCTION Malus sylvestris Mill., the apple species native to Europe, is one of the most endangered tree species in Lithuania; those that remain are very scattered.
