Abstract:
Fifty cultivated Perilla seeds were collected all over the country and planted in Beijing experiment field for morphology and chemical-type researches. Twenty morphological characteristics were selected and observed, and the essential oil from leaves was extracted by steam distillation and analyzed by GC-MS to confirm chemical-types. There were significant diversities in plant height, leaf color and morphology, and fruit color and weight. Clustering analysis was carried out based on these morphological characteristics. Six types were divided with their chemical-type designated. Type Ⅰ: Six germplasms, attributed to P. frutescens var. crispa, with dwarf plants, thin creased purple leaf, named Crispa, their chemical types were diversified, including EK, PAPK, PA and PK. Type Ⅱ: Six germplasms, attributed to P. frutescens var. crispa, plants were taller than type I and with thin and creased green leaf, named Big Crispa, all PK type. Type Ⅲ: Seventeen germplasms, attributed to P. frutescens var. frutescens with leaf color upside green and underside purple, tall plant and wide distribution all over the China, named Ordinary Frutescens, all PK. Type Ⅳ: Four germplasms, attributed to P. frutescens var. acuta with tall plant and small seed, named Acuta, all PK. Type Ⅴ: Seven germplasms, attributed to P. frutescens var. frutescens with green leaves, tall plants and long clusters, named Long-spike Frutescens, all PK. Type Ⅵ: Ten germplasms, attributed to P. frutescens var. frutescens with big, thick and creased leaf, named Thick-leaf Frutescens, including PK, PP, PL and PA. The morphological classification of this paper would lay the foundation for the taxonomic naming and following evaluation of the Perilla germplasm resources.This study also showed that there was no correspondence but a certain correlation between volatile oil chemical-types and subspecies classification and morphological characteristics of Perilla.
