Horticultural Science and Production in Iran at a Glance
Morteza Khosh-Khui 한국원예학회 2009 Horticulture, Environment, and Biotechnology Vol.50 No.6
Iran, officially Islamic Republic of Iran, is a country in southwest Asia with an area of 1,648,000 sq ㎞, and an estimated population of about 70 millions. It is bordered on the north by the Caspian Sea and the republics of Armenia, Azerbaijan, and Turkmenistan; on the east by Afghanistan and Pakistan; on the south by the Persian Gulf and the Gulf of Oman; and on the west by Turkey and Iraq. Iran lies on a high plateau surrounded by the Zagros Mountains, running from the Armenian border to the shores of the Gulf of Oman, and in the north by the Elburz Mountains. An extensive salt desert inland is separated from a sand desert by two mountain ranges in the east. Iran is located in the semi-arid region of the world. The average annual rainfall is about 240 ㎜ with a wide variance ranging from less than 50 ㎜ in the central desert, up to 1,500 ㎜ in the northern areas. Iran is one of the most important producers and exporters of horticultural products in the world and based on FAO statistics, Iran ranks first in fruit and second in vegetable production in the Middle East. In this paper, horticultural education in universities and main institutions active in horticultural science including Iranian Society for Horticultural Science are introduced. Being a vast country, Iran has 11 out of 13 world climates from temperate-zone to subtropical and tropical climates and is a unique country capable of producing all types of fruits. The production of main crops including fruits, vegetables, flowers, spices and medicinal plants are described. Some results of horticultural researches carried out in Iran and some statistics of horticultural production and industry are presented and potentials and challenges of Iranian horticulture are discussed. In addition to the domestic market, Iran has a major share of export for many major fruits, vegetables and recently flowers in the global market. Particular attention is made on crops suitable for export and also on showing the share of Iran in world production of main crops. Finally, in an overview, limitations that are impediments in horticulture of Iran will be identified and suggestions will be made for further improvements in future.

Phylogenetic Relationships among Seven Old Rose Species Grown in Iran Revealed by ISSR Markers
Zohreh Jabbarzadeh,Morteza Khosh-Khui,Hassan Salehi,Adel Saberivand 한국원예학회 2010 Horticulture, Environment, and Biotechnology Vol.51 No.3
Roses are among the most economically important ornamental crops. Inter-simple sequence repeat (ISSR) markers were used to study phylogenetic relationships among 7 rose species. Among 9 ISSR primers, 6 primers showed acceptable polymorphism and amplified 66 bands of which 50 were polymorphic. Banding patterns were transformed into binary data of presence-absence and matrices were processed using NTSYS pc 2.02 software program. The dendrogram was constructed using Jaccard coefficient and UPGMA algorithm. The 7 rose species were classified into 3 major groups with within-group similarity values of >0.58. Group 1 included R. banksiae; group 2, R. canina, R. chinensis, R. damascena, R. moschata and R. hybrida; and group 3, R. foetida. None of the species used in this study clustered within group 1, indicating that there is no direct relationship between these species. The species that were placed with R. hybrida in group 2 are the ancestors of R. hybrida and because of other species except these four species have contributed to the gene pool of modern garden roses, 59% similarity between these roses in this study was expected. In this phylogenetic tree R. foetida clusters in the lower part of the tree showed 49% similarity with group 2.

Tulip ( Tulipa L.) is one of the most important ornamental geophytes in the world. Analysis of molecular variability of tulipsis of great importance in conservation and parental lines selection in breeding programs. Of the 70 genic microsatellites, 15highly polymorphic and reproducible markers were used to assess the genetic diversity, structure, and relationships among280 individuals of 36 wild and cultivated tulip accessions from two countries: Iran and the Netherlands. The mean valuesof gene diversity and polymorphism information content were 0.69 and 0.66, respectively, which indicated the high discriminatorypower of markers. The calculated genetic diversity parameters were found to be the highest in wild T . systolaStapf (Derak region). Bayesian model-based STRU CTU RE analysis detected fi ve gene pools for 36 germplasms whichcorresponded with morphological observations and traditional classifi cations. Based on analysis of molecular variance, toconserve wild genetic resources in some geographical locations, sampling should be performed from distant locations toachieve high diversity. The unweighted pair group method with arithmetic mean dendrogram and principal component analysisplot indicated that among wild tulips, T . systola and T . micheliana Hoog exhibited the closest relationships with cultivatedtulips. Thus, it can be assumed that wild tulips from Iran and perhaps other Middle East countries played a role in the originof T . gesneriana , which is likely a tulip species hybrid of unclear origin. In conclusion, due to the high genetic variabilityof wild tulips, they can be used in tulip breeding programs as a source of useful alleles related to resistance against stresses.

This research was conducted to investigate the effects of natural zeolite on vegetative growth, flower and physiological characteristics of African marigold (Tagetes erecta L. 'Queen'). The experiment was performed as a completely randomized design with six treatments (2, 4, 6, 8 and 10 g zeolite/kg soil mixture along with control) and 5 replications. Results indicated that zeolite decreased leaching of nitrogen, potassium, phosphorus, calcium, and magnesium due to increase in cation exchange capacity (CEC) of soil mixture. Application of zeolite in the medium resulted in significant increase in photosynthetic rate, mesophyll efficiency, water use efficiency, chlorophyll content, fresh and dry weights of roots and shoots, leaf area and flower length, but did not significantly affect flower diameter and stomatal conductance. It was concluded that zeolite had a pronounced effect on vegetative growth, flower and physiological characteristics of African marigold. It my be recommended that zeolite being used, as an amendment to soil of ornamental plants such as African marigold to decrease nutrient leaching and irrigation interval.
