Illicium Verum Hook.F.Blossoin And Young Fruit Period Source Hormone Change Research

Illicium verum Hook.F.is one of the important economic forest tree species in guangxi,and at the same time,the fallen petal fruit abscission,appear missing Angle phenomenon,in the spring of fruit production changes,in order to explore Illicium verum Hook.F.endogenous hormones and blossom and bear fruit,the relationship between ordinary branch to branch type different colors Illicium verum Hook.F.,pale red flowers in different types of branch Illicium verum Hook.F.as the research object,in front of the budding stage,budding,full bloom,the fallen petal and young fruit period,sampling analysis of endogenous hormones,investigation of Illicium verum Hook.F.flowering amount,the fallen petal fruit abscission rate,bud size,proportion of spring fruit and spring blended heavy,analysis of Illicium verum Hook.F.the changes of endogenous hormones in the flowering period and young fruit period and differences,the endogenous hormones of Illicium verum Hook.F.flowering amount,the fallen petal fruit abscission rate,bud size,proportion of spring fruit and spring blended heavy impact.The main results were as follows:1.Flowering quantity order for spring pin>annual branches>biennial branches born three years>perennial branches,branches and the spring pin as the main flowering branches,more than 60%of the amount of total cost.ZR,IAA,GA3 content and various types of Illicium verum Hook.F.flowering amount are positively correlated relationship,and ABA content and with various types of Illicium verum Hook.F.are in negative correlation between the amount of flowering.2.Before the budding stage,budding,coated,out,out,out of a month after two months,three months after the fallen petal,four months after the fallen petal,different colors endogenous hormone,ZR,IAA,GA3,ABA content is significant difference,different branches endogenous hormone content of ZR,IAA,GA3,ABA significant difference.3.In Illicium verum Hook.F.In the process of flowering,ZR,GA3 content has a rising trend,IAA content have obvious rising trend,and ABA content have obvious downward trend.4.Before the budding and budding period,ZR,IAA,GA3 content and various types of Illicium verum Hook.F.flowering amount are positively correlated relationship,and ABA content and with all kinds of Illicium verum Hook.F.are in negative correlation between the amount of flowering.That endogenous hormone,ZR,IAA and GA3 can promote Illicium verum Hook.F.flowering,while ABA can inhibit Illicium verum Hook.F.flowering.5.In Illicium verum Hook.F.young fruit period,IAA content at first and lowered later GA3 content has a rising trend,ABA content increased after fall first,but the content of ZR because of Illicium verum Hook.F.types have different changes,show higher GA3 content may be associated with seed formation,promotes Illicium verum Hook.F.fruit growth.6.Each type of Illicium verum Hook.F.fallen petal rate is generally about 40%,fruit abscission rate with time slowly increases leveled off in the end.Out of phase,ZR content in relation to fallen petal rate because of Illicium verum Hook.F.varies types.IAA,GA3 content and various types of Illicium verum Hook.F.are in negative correlation between the fallen petal rate.And ABA content and various types of Illicium verum Hook.F.fallen petal rate are positively correlated.IAA,GA3 could suppress Illicium venrum Hook.F.fallen petal,while ABA will promote Illicium verum Hook.F.fallen petal.7.A month after the fallen petal to fallen petal after four months,ZR,GA3 content and fruit a'bscission rate relationship over time because of Illicium verum Hook.F.type varies.IAA content and various types of Illicium verum Hook.F.are in negative correlation between the fruit drop rate.And ABA content and various types of Illicium verum Hook.F.were positively correlated.That IAA could suppress Illicium verum Hook.F.fruit drop.While ABA will promote Illicium verum Hook.F.fruit drop.8.The types of the same branch different colors Illicium verum Hook.F.endogenous hormone,ZR,IAA,GA3,ABA content and the relationship between the bud size because of Illicium verum Hook.F.type varies.Branch of the same design and color is different types of Illicium verum Hook.F.endogenous hormone ABA content are negatively related with the bud size,ZR,IAA,GA3 content and the relationship between the bud size because of Illicium verum Hook.F.type varies.9.Various types of Illicium verum Hook.F.spring fruit Numbers were greater than autumn fruit number,and the proportion of spring fruit at around 70%.GA3 content and proportion of various types of spring fruit were positively correlated,GA3 content is Illicium verum Hook.F.spring form one of the main causes of fruit.While ZR,IAA and ABA content and proportion of spring fruit relationship because of Illicium verum Hook.F.type varies.10.In the spring of the average fruit weight at about 35 g.ZR,IAA,GA3 content and various types of Illicium verum Hook.F.spring fruit weight were positively correlated relationship,but the content of ABA and negatively correlated with fruit weight spring.ZR,IAA,GA3 can promote Illicium verum Hook.F.spring fruit growth,while ABA can inhibit Illicium verum Hook.F.spring fruit growth.
