Growth characteristics
Structure and life cycle:. 1. The flower bud of peony bud bud to mix, belongs to the underground bud type, smoke out of the ground is cassia leaf after germination, and exhibition of flower buds Mixed bud is the compound of a variety of primordium, by growing point at the top, bud scale, bud scale in axils of lateral bud primordium, leaf primordium, Ye Yuan shame in axils of lateral bud primordium, urine bract primordium, sepal primordium, petal primordium, stamen primordia and pistil primordium, etc. The bud called generation of bud, bud scales and leaf primordium in the axillary lateral bud primordium is offspring buds of the original body Within the leaf primordium axillary and axillary bud no bud scale for naked bud primordium;. And scales in axils of lateral bud primordium bud scale, form bulbil Spring bulbil germination, offspring naked shoots with the generation of mixed bud internode elongation and stretch out the ground, form the trunk or branches;.. The offspring bulbil not above the ground After being the wineries wither above ground , located in the root extract the neck the top of offspring bulbil became a "crown". Peony crown is only one, in fact be the seed germination, the's west crown. The following year, the offspring bulbil germination unearthed, branch, leaf, flower. So, naked shoots life cycle for 2 years, and bulbil life cycle for 3 years.
2.
