Matures Old 50 -

: Using a spectrophotometer, DNA concentration in old leaves ranged from 981.8 ng/µl to 398.34 ng/µl , showing higher variability and potential contamination compared to younger tissue.

: The purity of the DNA is checked at 260 nm and 280 nm . Values in the range of 1.8 to 2.0 are considered "pure," whereas mature leaves often show lower ratios due to the presence of proteins and organic compounds.

Researchers compared the efficiency of DNA extraction from new 7-day-old flushes versus . : Using a spectrophotometer, DNA concentration in old

: New leaves are preferred because mature leaves contain higher concentrations of polyphenolic compounds and polysaccharides , which make the grinding process difficult and interfere with DNA purity. If you'd like, I can: Draft a full

: New flushes yield significantly more DNA. In studies, new leaves produced a clear, transparent pellet, while 50-day-old leaves produced a yellowish or brownish pellet.
