The Research Of Camphor’s Different Family Growth Characteristics And Seeds Selection

Taking pine creek state-owned forest farm of Fujian province, Fujian Nanping state-owned forest farms on the outskirts of teaching, Fujian Yongan forestry co., LTD. Yanshan CaiYuChang, yonhap dongpo state-owned forest farm of Fujian province four tested for 4 years and 8 years family determine camphor forest as the research object. Investigating the growth character, determination and analysis, carry out the good pedigree selection material with camphor. Through the analysis of variance, nonparametric test, principal component analysis and cluster analysis to choose the level of six lines. According to the volume of real genetic gain selected 12 superior individual plant.1, The first 8 a, camphor tree height growth rule:in 1～8 a, average tree height growth is a downward trend in general; In 1～3 a, tree height growth is greater than 0.80 m for years, undergoing fast tree height growth period; Several years of growth in 4～8 a tree height is less than 0.80 m, tree height growth slowed.2,8 a, camphor DBH growth rule:in 1～3 a, DBH growth growing for years, in 3 a peak, is greater than 2.00 cm, in DBH fast growth period; In 3～8 a, DBH growth falling for years, DBH growth slowed.3,8 a, camphor volume growth rule:in 1～8 a, the average volume growth is on the rise in general; Several years of growth in 2～3 a, volume growth, the largest in the several years of growth peak,7 a closer to 0.0025 m after; In 3～8 a, volume growth is greater than 0.001 m after for years, in a volume rapid growth period.4, About the growth index of variance analysis, the results showed that the tree height, DBH and volume growth were extremely significant differences between index system at home. This difference makes camphor has great potential to choose for the generation of camphor breeding, directional selection, provides the reliable rich germplasm resources and breeding materials.5, Respectively to four tested of camphor tree height, DBH and volume of nonparametric test, the result indicates that, between the four tested, camphor tree height, DBH and volume were significant differences.6 Pine creek state-owned forest farm of Fujian province, analysis of the top five good family situation, the results showed that the pine creek state-owned forest farms in Fujian province, with four of the top five from the family from Minqing provenance family; Analysis of Fujian Nanping state-owned forest farm on the outskirts of teaching in the top five good family situation, the results show that in Nanping Fujian province state-owned forest farm on the outskirts of teaching with four of the top five from the family home from yeonpyeong provenance system.7,60 of four tested camphor family clustering analysis, the results show that there exist certain differences between each department, there is biggish difference between a variety of sources, but different from the same provenance family there is a certain degree of similarity between.8, Camphor superior individual selection of four tested, screening out the fine individual volume of reality by genetic gain is very high, the results show that:in the process of practical production of superior individual selection is necessary, can achieve higher gain.9, The contrast of four testing different years to screen out good pedigree and superior individual camphor, the results show that good family and superior individual in different tested, its excellent characters unstable; Good family and superior individual at different growth stage, its excellent characters performance is not stable.
