چکیده
The crown width of a tree is very important parameter. It responsible for survival and producing the food whole tree. They produce oxygen, filter out dust other airborne pollutants from air, purification water, generate shadow determine scenic beauty trees forests. crowns have significant effect on microclimate. But measuring difficult task that needs much money, time effort. Thus this study aimed at developing mathematical relationship between breast height diameter Chinaberry grown in Sami Abdulrahman Park Erbil, Iraq. Both diameters are most parameters can be measured easily using tape or caliper, unlike which more cumbersome. Therefore, it accustomed to regress with equations.to used prediction instead whenever needed. Such regression models were undergone many measures precision order select appropriate one best fits collected dataset. In 50 developed, 25 included y- intercept was without Y-intercept. first group excluded competition list because having low values coefficient determination. second equations subjected criteria purpose selecting last equation: finally selected its high ability simplicity application. According equation (Sami Erbil) increases 1.50168m each unit increase .

Study on the extraction process and seasonal variation of Toosendanin in Chinaberry (Melia azedarach L.)
Toosendanin as one kind of plant pesticide exists in the fruits, barks, and leaves of Melia azedarach L. (chinaberry tree). To obtain toosendanin, the sample was defatted with petroleum ether, extracted with ethanol; then the solution was concentrated, and extracted with ethyl acetate. Uniform design and regression analysis were employed to establish a model of extraction and optimize the proce...
متن کاملPotent limonoid insect antifeedant from Melia azedarach.
Systematic fractionation of a fruit extract from Argentine Melia azedarach L., which was monitored by an insect antifeedant bioassay, led to the isolation of meliartenin, a limonoid antifeedant, which existed as a mixture of two interchangeable isomers. At 4 microg/cm2 and 1 microg/cm2, the isomeric mixture was as active as azadirachtin in strongly inhibiting the larval feeding of Epilachna pae...
متن کاملEstimation of Tree Biomass at Individual tree, Sample plot and Hybrid Level using Drone Images
Two-dimensional image conversion algorithms to 3D data create the hope that the structural properties of trees can be extracted through these images. In this study, the accuracy of biomass estimation in tree, plot, and hybrid levels using UAVs images was investigated. In 34.8 ha of Sisangan Forest Park, using a quadcopter, 854 images from an altitude of 100 meters above ground were acquired. SF...
متن کاملCytotoxic tirucallane triterpenoids from Melia azedarach fruits.
The phytochemical investigation of the dichloromethane-soluble part of the methanol extract obtained from the fruits of Melia azedarach afforded one new tirucallane-type triterpene, 3-alpha-tigloylmelianol and three known tirucallanes, melianone, 21-beta-acetoxy-melianone, and methyl kulonate. The structure of the isolated compounds was mainly determined by 1D and 2D NMR experiments as well as ...
