Research On The Rule Of Abloom And Seed Growth Of Hazel

Hazel is one of the economical trees which have value of use. In the Europe had gone into intensive cultivation now, but development of the hazel production had in the forepart in our country, and a lot of investigation hadn't began or consummate. Recently hazel which has been bought mostly is wildness. Besides the growth and fetching in breeds have many questions. Thus it can be seen , enhancing the output and the quality was the emphases.Contra pose these phenomena, we use for other fruit trees investigation and amelioration in these. We studied the all the florescent and burliness phonological. We discussed from the time of abloom and the florescence,most fitting temperature and humidity in the process of growth of the hazel pollen,availability pollination and fecundation time,the rule of seed growth,contention of mineral element in hazel leafs. And we studied three genuses as Corylu .heterophylla. Fisch,Corylu heterophyll.Fissch×Corylus,avellana L and Corylus acellana L.We observed the time of abloom and the florescence in three genuses. Stat the he time of abloom and the florescence, combine the temperature of the pilot plant. As a result, we found that the mostly fit temperature is 10℃around for bloom, the beginning of abloom temperature is 4℃around, the male flowers have different in beginning of abloom temperature: Corylus acellana L and Corylu heterophyll.Fissch×Corylus,avellana was 4℃, Corylu .heterophylla. Fisch is 6℃around , and when the temperature in daytime under -5℃the hazel was frozen easily. The female florescence of three genuses closely is 12-13 days; the male florescence has a little different.Controlled the condition of temperature and humidity in the process of growth of the pollen, and observed the pollen vitality in different term of three genuses. Studied the pollen vitality, we can find these: The mostly infection factor is the temperature. In the different temperature levels have obvious difference. The temperature 10 is the most fitting; In the different genus don't have the obvious difference.Using manual work pollination, controlled the time of pollination, and investigates the rate of seed. Found that the three genus have the same availability pollination time, they are behind the abloom 24hours and 48hours, and they availability fecundation time have a little different. Beside the rate of fall seeds have different in variously, and the manual pollination can enhance the rate of seed.Measured seeds and pip mass in the procession of seeds growth, and contents of endogenous hormones in hazel. We can find that, three genus hazel the mass and cubage rule were"fast-slowly–fast"called〝Double-S〞curve. Pip was growing by the time. Besides IAA,GA3,ABA have change as rule in the procession of seeds growth, these approved that the hormone plays a important role in seeds growth. We measured the mineral elements of leaves in the growth annual, stated and plot. The result showed that ,in the three genus, the content of mineral elements in leaves were similar in Corylus acellana L and Corylu heterophyll.Fissch×Corylus,avellana but same of the elements were lower in Corylu .heterophylla. Fisch., so we can know that the growth circs of Corylu .heterophylla. Fisch was bad than other. But the changing rule of the elements was similar in all of them. Meanwhile, between Zn²⁺ and Ca²⁺, Mn²⁺ and Cu²⁺ showed remarkable or extremely remarkable relativity; between Mn²⁺ and Ca²⁺, K+ and Zn²⁺, K+ and Mn²⁺ showed extremely remarkable positive relativity.
