The Optimized Rooting Condition Of Haloxylon Ammodendron And The Research Of Physiology And Anatomy In Rooting

Cistanche deserticola Y.C.Ma for the column when the branch (Orobanchaceae) Cistanche (Cistanche)perennial, of camp spot root parasitic plants. Its host plants to the Chenopodiaceae Haloxylonammodendron (Haloxylon ammodendron (C.A.Mcy.) Bunge), is a desert in Northwest China rare plantresources in the semi-desert environment. This experimental from on host plant Haloxylon ammodendronof ecological recovery forest of can continued recovery uses of angle starting, early on Cistanche parasiticon Haloxylon ammodendron of growth of effect for has investigation, then through outside source hormoneregulation on host plant Haloxylon ammodendron health root of test, clear Haloxylon ammodendronseedlings of health root conditions of optimization and Haloxylon ammodendron health root Shi health rootassociated enzyme (effects effect acetic acid oxidation enzyme, and more phenol oxidation enzyme, andperoxide enzyme) of dynamic changes, while on Haloxylon ammodendron roots for Anatomy experimental,clear Haloxylon ammodendron health root of mechanism, Thus planted desert meat boschniakia glabravaccination rates and organization of Haloxylon ammodendron and rapid propagation techniques of studyprovide theoretical basis. Main conclusion as follows:1.The results showed most height, crown size and base diameter of the monthly average growth rate ofthe investigated objects A was smaller than that of the CK. The new branches of the investigated objects Areached maximum time lag behind that of the CK. It shows that these new branches growth of hostH.ammodendron were restrained greatly after H.ammodendron was planted artificially Cistanchedeserticola. The main root of H.ammodendron is well developed and the proportion of the fine root ishigher. This is benefit to the growth of Haloxylon ammodendron and provide nutrition for parasitism inCistanche.2.Experimental studies have shown that when use the seed germination of Haloxylon ammodendronseedlings for rooting, a low concentration of salt, NAA, IBA concentration range of0.5-0.8mg/L and0.8-1mg/L is propitious to rooting.The rooting rate can reach86.7%and93.3%.3.Epidermal cells of the roots of Haloxylon ammodendron arranged closer, this structure can preventits reverse osmosis water to the sand layer. More cortical parenchyma help to store water and slow the lossof moisture, Haloxylon ammodendron developed xylem absorbs moisture and water transport has animportant role within the plant body. Endothelial cells are thin-walled cells projecting to cortex lateralprimordia, which shows lateral primordia occurs in pericycle cells. The roots of Haloxylon ammodendronwhere these structures clarify the absorption roots of Haloxylon ammodendron.4. The change of IAAO,PPO and POD of rooting related enzyme activity is closely related withHaloxylon ammodendron rooting.They have a certain regularity in the rooting process.The activity ofIAAO first increased and then decreased.The activity of PPO first decreased and then increased and thenleveled off.The activity of POD gradually increased to level off.Three enzymes are independent of eachother, and influence each other.They influence on the rooting of Haloxylon ammodendron mutual.
