Research Paper

Abstract

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 

Abbreviations

SE

standard error

VT

total respiratory rate

Vcyt

respiratory rate inhibited by cyanide

Valt

total respiratory capacity inhibited by SHAM and denoted alternate respiration

Vres

residual respiration

PMSF

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

SHAM

salicyl-hydroxamic acid
