야로비자치야 (춘화처리)
Vernalization (Yarovizatsiya)
겨울 곡물 종자를 파종 전에 저온·습윤 처리하여 봄에 파종해도 꽃을 피우고 결실하게 하는 농업 기술로, 트로핌 리센코가 1929년 '야로비자치야'라 명명했다. 1930년대 소련에서 전체 곡물 파종 면적의 13%까지 확대 적용되었으나 노동 집약성과 불확실한 효과로 전후에는 기장·감자 재배를 제외하고 폐기되었다. 본래 육종 보조 수단으로서 니콜라이 바빌로프도 지지했지만, 리센코는 춘화처리 상태가 유전된다고 주장하며 이 기술을 후천획득형질 유전의 증거이자 멘델유전학 공격의 발판으로 삼았다.

- 위키백과 (러시아어) Russian Wikipedia article covering the physiological basis, history, and Lysenko's role in naming and promoting yarovizatsiya; notes the term was coined in 1929 and that mass application reached 13% of USSR grain acreage by 1941 before being abandoned due to labor intensity and unreliable results.
- 위키백과 (영문) English Wikipedia article on the history of vernalization research; confirms Lysenko coined 'яровизация' in 1928–1929 and himself translated it as 'vernalization'; notes Gassner's prior 1918 work and that the technique had been known to farmers since the 19th century.
- 위키백과 (영문) Documents how vernalization was Lysenko's breakthrough technique that launched his career; he claimed the vernalized state was inherited, using it to attack Mendelian genetics as 'bourgeois pseudoscience'; Vavilov initially supported vernalization as a breeding tool before becoming Lysenko's target.

(2019) in Genetics: peer-reviewed historical analysis of the 1948 VASKhNIL session; details how Lysenko's vernalization project was one of the 'developments that promised quick results' demanded by the Stalinist state during the forced collectivization crisis.
- britannica.com Britannica entry on vernalization covering the physiological mechanism, genetic control (FLC, VRN genes), and agricultural applications, confirming vernalization's continuing scientific validity as a plant developmental process distinct from Lysenko's political use of it.
