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.

Researchers compared the efficiency of DNA extraction from new 7-day-old flushes versus . matures old 50

: 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. : 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. : Using a spectrophotometer
