Introduction
Nowadays across the world is particular attention for medicinal plants and their role in the production of drugs with no side effects. Our country with climatic extremes also have important role in the production of these plants in the world. Formulate and implement effective programs in line with the resuscitation conservation and efficient utilization of medicinal plants by identifying their characteristics and ecological needs is possible. Henna with the scientific name of Lawsonia inermis L. is a perennial plant having high value in terms of medicinal properties and industrial application. The dye which is derived from green leaves of henna is used for decorating the body with intricate designs and the principle coloring matter is lawsone, 2-hydroxy-1, 4-naphthoqunone (Prosen et al., 2005). Literature show henna possess antibacterial (Vinoth et al., 2013) and anti- immunomodulatory activities (Mikheil et al., 2004) along with other properties. The natural constituents of henna are essential oils, 1,4-naphthoquinone, tannins, gallic acid, flavonoids, lipids, sugars, triacontyltridecanoate, mannitol, xanthones, coumarins (5-alkyloxy 7-hydroxycoumarin), 2-3% resins, 5-10% tannic ingredients and up to 2% lawsone (2-hydroxy-1,4-naphthoquinone). A major portion of lawsone is glycosidic bound, which is cleaved by enzymatic hydrolysis of the glycosidichennosids and auto oxidation of aglucons. Review of findings shows that no studies have been done on the eco-physiological properties of henna in Iran. Kerman province with the first position in Hana production has a special importance in this regard.
Materials and methods
The study was carried out in Kerman province in 2015. In this survey climatic characteristics of cultivated area, physico-chemical analysis of soil, performance data, phenological stages and also information on irrigation were investigated. Finally, the relationship between climatic-management characteristics and performance was studied through multiple regressions.
Results and discussion
Introduction
Nowadays there is a global attention to medicinal plants and their role in the production of drugs with no side effects. Our country with climate variety also has important role in production of these plants in the world. Formulate and implement effective programs in line with the resuscitation conservation and efficient utilization of medicinal plants by identifying their characteristics and ecological needs is possible. Henna with the scientific name of Lawsonia inermis L. is a perennial plant having high value in terms of medicinal properties and industrial application.

A major portion of lawsone is glycosidic bound, which is cleaved by enzymatic hydrolysis of the glycosidichennosids and auto oxidation of aglucons. Reports of various studies show that no experiment have been done on the eco-physiological properties of henna in Iran. Kerman province with the first position in Hana production has a special importance in this regard.
Materials and methods
This study was carried out in Kerman province in 2015.In this survey climatic characteristics of cultivated area, physico-chemical analysis of soil, performance data, phenological stages and also information on irrigation were investigated. Finally, the relationship between climatic-management characteristics and performance was studied through multiple regressions.
Results and discussion
The results showed that the henna in Kerman province is distributed in Shahdad, Roodbar, Bam and Kahnooj. The area under cultivation in these regions ranged from a minimum of 3 hectares with a yield average of 1.4 ton/ha in Shahdad and a maximum of 7500 hectares with a yield average of 6.5 ton/ha in the Roodbar. The results of this study showed that over 93% of henna cultivation area in Kerman province belongs to Roodbar. The highest and lowest of water use efficiency were belonged to Roodbar (0.46) and Shahdad (0.17) respectively. The total growth period, on average, varied between 190 to 220 days in the studied areas. Climatic zoning of habitat areas were dry climate according to Domarten dryness index. The mean annual precipitation of habitats were 7.72 mm, 33.6% relative humidity, 632 m altitude and the mean temperature was 26.5 ° C. Soil of habitats largely had sandy-loam texture with an pH of 8.19, 3.84 dS/m electrical conductivity and 0.06-0.12% organic matter. The results of stepwise regression analysis showed that nitrogen, rainfall and relative humidity are the most important soil and climate characteristics that affect henna performance , respectively. Availability of nitrogen has a great importance because of their role in the production of proteins, nucleic acids and chlorophyll synthesis. Rainfall is one of the most important climatic factors that can be more effective in yield production through the influence of moisture and soil temperature.
Conclusion
Henna is a cold-sensitive species while able to growth in dry climates with an annual precipitation of less than 100 mm. According to recent studies the plant cultivation area in previous years has been more than now. Some problems such as water shortages, agricultural economic problems and etc. have been effective in reducing the cultivation area. In general, due to the importance of medicinal plants, it is necessary to study the various ecophysiological aspects of henna, providing a solution for optimized management and consequently extending area under cultivation in the local areas of the country.
