The results show that the suitable areas （which contain highly suitable, generally suitable, and critically suitable areas） for R. damascena trigintipetala are 307.268×lO4 hm^2, which accounts for 6.34% of the total provincial area. Results also indicate that shrub land and open forest land are the major land-use types suitable for R. damascena trigintipetala, with the suitable areas of 303.162×lO4 hm2 （6.25% of the total provincial area）. An introduction test was conducted in one of the suitable areas, Xichang City, which demonstrated that R. damascena trigintipetala grows well at theexperimental sites. The quality of rose oil extracted from R. damascena trigintipetala planted in Xichang meets the Bulgaria Rose Oil Standard, thus verifying the accuracy and reliability of the ecological suitability assessment results.展开更多

The purpose of this study is to identify the colour effect of flower through the quality effervescent tablet, to know the interaction between the flower colour and the sugar type through the quality effervescent rose tablet. This study was done with two steps. Step I was divided into 2 levels of examinations using simple random： Rose colouring, M1 （dark red） and M2 （pink）, while step II consisted of three levels of examinations, those were G 1 （sucrose）, G2 （dextrose）, and G3 （sorbitol）. The result showed that the dark red colour has a better extract pigment quality, the level of the light color （L） was 77.3 and the redness level （b＋） was 25.033. The best rose effervescent tablet was produced by the combination of M 1 G3 （dark red： corn sugar/sorbitol）, that has 8.179% of water content; the solute velocity was 0.029 g/sec; the lightness level （L） was 84.133, the redness level （a＋） was 18.3. The product of the rose effervescent drinks has a value of 6.46 pH; viscosities 342.867 cps and total of sugar 52.150%.展开更多
