Source-derived summary

Mikhail Khristoforovich Chailakhyan (Armenian: Միքայել Քրիստափորի Չայլախյան, Russian: Михаи́л Христофо́рович Чайлахя́н; 1902–1991) was a Soviet Armenian scientist who is widely known for proposing the existence of a universal plant hormone that is involved in flowering. He named this hormone florigen in 1936. His studies included the mechanisms of flowering, tuberization and sex expression in plants. His pioneer work included the agricultural applications of phytohormones and synthetic analogs.

Editorial summary

This brief starts where responsible research should: with the source description of “Mikhail Chailakhyan” as russian botanist (1902-1991). Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1902, 1991, 1936—that can be checked directly. The linked authority record independently contributes the date 1902-03-08. The account is most persuasive where Mikhail, Chailakhyan and Russian can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as russian botanist (1902-1991). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 29, 2026. The linked authority identifier is Q6849524. VIAF identifies the subject as 76940013. The Library of Congress control number is n84223568. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1902, 1991 and 1936.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
