Observation Friable callus formed from shoot tip and leaf primordial explants.
Intervention effect The medium with 100 mg/L 2,4-D and 3 mg/L 2iP gave the highest callus initiation percentage.
Intervention effect Sewi achieved 87.5% embryogenic callus with the stated medium.
Intervention effect Sewi produced an average of 5.16 somatic embryos on 0.1 mg/L NAA medium after three subcultures.
Intervention effect Oshkingbeel produced an average of 4.94 somatic embryos on 0.1 mg/L NAA medium after three subcultures.
Intervention effect The specified solid medium yielded greatest embryonic elongation and highest leaf number.
Observation Plantlets developed and grew well in rooting MS medium with 1 mg/L NAA.
Observation Acclimatization percentage declined over four months in the first stage.
Observation Date palm survival was low in the first acclimatization stage.
Observation Date palm survival was very high in the second acclimatization stage.
Observation Date palm survival stabilized after another six months with good growth.

3 of 4 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
