Research Paper


Lactuca serriola L., which was found to enter skotodormancy at a relatively low temperature, was used to try and ascertain differences in thermo- and skotodormancy.

Key words

Thermodormancy skotodormancy Lactuca serriola hormones respiration ethylene synthesis protein synthesis 



standard error


total respiratory rate


respiratory rate inhibited by cyanide


total respiratory capacity inhibited by SHAM and denoted alternate respiration


residual respiration


phenylmethylsulfonyl fluoride; panacide, 5,5′-2,2′-dihydroxydiphenylmethane


salicyl-hydroxamic acid
