Preface

The importance of post-harvest operations in developing countries relies in the quality control of the fresh fruit that they achieve. Post-harvest operations begin with a selection of the fruit, then a cleaning, packing, proper storing and transporting. All these operations benefit producers because they enable the fruit to reach the market at higher prices, and also create jobs in the packinghouses and orchards for both educated and non-educated labor. The domestic and international consumer benefits with a high-quality fresh fruit, free of diseases and other defects.

Avocado is a fruit with an exquisite taste and aroma, which has been traditionally consumed even before the arrival of Spaniards to the Americas. It is called “aguacate” or “palta” in LatinAmerican countries. Nowadays, as a result of different investigations, it is recognized that besides being a source of energy and vitamins, it also delivers specific non-nutritive physiological benefits that may enhance health. From this point of view, avocado can be considered as a “functional food”, according to the definition of Mazza (1998). Some nutraceutical ingredients that have been found in avocado pulp are antioxidants, such as vitamin E or tocopherols (4.31 UI/100 g) and glutathion (17.7 mg/100g). They both work as antioxidants, neutralizing free radicals that may damage aging cells, the heart, and contribute to the development of some types of cancer, such as mouth and pharynx (O’Toole, 2000, Heber, 2001). It has also been reported that avocado is a source of lutein (248 mg/100g, considered a high content), a carotenoid that helps to protect the eye from diseases such as cataracts. The amount of b-sitosterol in this fruit is similar to the one found in soy and olives. Animal studies have demonstrated that this compound is related to the inhibition of cancerous tumors (Heber, 2001). An other nutraceutical component in avocado is a mix of high quality lipids: w3, w6, and w9 fatty acids. When Carranza et al (1997) made clinical studies in patients with high cholesterol levels, they found that an avocado enriched diet produced a significant reduction in low density lipoproteins (“bad cholesterol”) and total cholesterol, while diets enriched with soy and sunflower did not change the total cholesterol concentrations. Lerman et al in 1994 concluded that in non-insulin dependent diabetic patients it was beneficial to replace carbohydrates for lipids, such as the ones found in avocado. This will favor the reduction of triglycerides in the blood plasma. For all of the above, it can be concluded that the inclusion of avocado in the everyday diet can bring health benefits to the health of human beings, bearing in mind that no food is 100% complete, and a single food will not provide all required nutrients and nutraceuticals (except for breast milk). The diet shall include several food items from all the different groups in
order to deliver a good nutrition.

Türkiye’de Avokado Yetiştiriciliğinin Gelişimi, Önemi ve Önerilen Bazı Çeşitler

TÜRKİYE’DE AVOKADO YETİŞTİRİCİLİĞİNİN GELİŞİMİ, ÖNEMİ VE ÖNERİLEN BAZI ÇEŞİTLER

Özet

Dünya’da avokado sınırlı alanlarda yetiştirildiği ve önemli bir besin değerine sahip olduğu için yüksek fiyatlarda alıcı bulmaktadır. Ülkemizde Akdeniz bölgesinde yaygın olarak ticari yetiştiriciliği yapılan birçok bitki türünün pazarlanmasında, ekonomik nedenlerden dolayı bazı dönemlerde sorunlar ortaya çıkabilmektedir. Bu sorunların çözümü için avokadonun ticari yetiştiriciliğinin yaygınlaştırılması, önemli bir alternatif olarak düşünülmelidir. Dünya avokado üretiminde ilk sıraları alan ve yaklaşık ihracatın % 80’ini karşılayan Meksika, Şili, Peru, Dominik Cumhuriyeti, Kenya ve Güney Afrika gibi ülkelerle kıyaslandığında, ülkemizin Avrupa’daki tüketim pazarlarına coğrafik  yakınlığı çok önemli bir avantaj olarak ortaya çıkmaktadır. Ülkemize avokado çeşitleri 1970’li yılların başında girmiş ve Akdeniz sahil şeridinde yayılış göstermiştir. Avokado çeşitlerinin ülkemize adaptasyonu konusunda en kapsamlı çalışma, 1989–2004 yılları arasında BATEM’de yapılmış ve toplam 42 çeşit denenmiştir. Sonuç olarak, ‘Bacon’, ‘Fuerte’, ‘Hass’, ‘Zutano’ ve ‘Ettinger’ çeşitlerinin bölge şartlarında yetiştiriciliğinin yapılabileceği tavsiye edilmiştir.

IMPORTANCE OF AVOCADO CULTIVATION, CRUISING AND PROPOSED SOME VARIETIES IN TURKEY

Abstract

Avocado is a cash crop due to its limited production area and high nutritional value. Many crops commercially produced in Mediterranean region, Turkey, have very often faced marketing problems and significant price fluctuations. Extending avocado production in Mediterranean region is seen as a viable alternative to overcome the problem. Turkey has a geographic advantage, with its proximity to Europe, over major exporters like Mexico, Chile, Peru, Dominic Republic, Kenya and South Africa that provides 80 % of demand. Being introduced in 1970, avocado has entertained expansion for production area in coastal region of Mediterranean region. The largest adaptation study was carried out in BATEM from 1989 to 2004 where 42 cultivars were evaluated. As a result, ‘Bacon’, ‘Fuerte’, ‘Hass’, ‘Zutano’ and ‘Ettinger’ cultivars have been recommend for commercial production in the region.
