Description | GenCatch TM Plasmid DNAMini Preparation provides a simple, fast and cost-effectivemethod to purify plasmid DNA without phenol/chloroformextraction. It is based on binding of DNA to silica-basedmembranes in a chaotropic salt. An average yield of 1-20 ugplasmid DNA can be expected from 1-5 ml overnight bacterialculture. | ||||
Detailed Components | High quality spin columns, collection tubes together with buffers and protocols. | ||||
Features | Fast: Up to 24 samples can be readily prepared in 30 minutes with minimum efforts. Flexible: Mini columns can used in either centrifugation procedure or using a vacuum manifold. Convenient: No phenol extractions or ethanol precipitations required. Yield:4-20μg of DNA from 2ml of culture Quality DNA prepared by this kit is suitable for many downstream molecular manipulations including PCR, ligation, restriction enzyme digestion, transformation and transfection, radioactive and fluorescent sequencing. | ||||

短截就是把枝条剪短,主要作用是促使其抽生新梢,增加分枝数目,以保证树势健状和正常结果。短截常用于骨干枝组修剪,结果枝组修剪,和树体局部更新复状。
短截按其长度可分为:
① 中短截:在一年生枝的中部短截,剪后萌发的顶端枝条,长势强,下部枝条长势弱。
② 重短截:剪去一年生枝的2/3。剪后萌发出的枝条较强状,一般用于主侧枝延长头修剪。
③ 重剪:剪去一年生枝的3/4-4/5,剪后萌发出的枝条长势强状,常用于发育枝作延长枝头和徒长果枝,中果枝的修剪。
④极重短截:剪去一年生枝的4/5以上,萌发后的枝条中庸偏状,常用于将发育枝和徒长枝培养结果枝组。
⑤留基部2芽剪:剪后萌发枝条较旺盛,常用于预备枝的修剪。对于幼龄树,树势较旺,以培养良好而牢固的树形结构,提早结果为主要目的,以轻短截,少疏间为主,从始果期到盛果期,主要使桃树多结果,并形成好的树形。
如果用组织DNA提取试剂盒,提出来的就是组织细胞的DNA了
