Abstract

Polyploid breeding is an efficient way to cultivate lilies with strong environmental adaptation and diverse morphological variations. Lilium ‘Siberia’ is an Oriental hybrid with high horticultural value and is widely used in the cut flower industry.
In this study, aseptic scales and bulb scales of Lilium ‘Siberia’ were subjected to obtain multiple genotypes of tetraploids, which were soaked or co-cultured with various filter sterilized colchicine solutions for various times after different pre-culture periods.
The results reveal that the highest induction rate of up to 30% was achieved after soaking the aseptic scales in a 0.02% colchicine solution for 36 h, with a total of 26 tetraploid plants obtained.
Flow cytometry analysis confirmed that the DNA content of tetraploids was twice than that of diploids, and chromosome counting indicated tetraploids had 48 chromosomes, and diploids had 24 chromosomes.
Morphologically, compared with diploid lilies, tetraploid lilies exhibit thicker, wider and longer leaves, with slight wrinkles on the leaf surface.
Microscopic observations showed that the length and width of stomatal and guard cell increased and stomatal density reduced in polyploids.
The chloroplast number of guard cell was reduced significantly in tetraploids compared to diploids.
Physiological detection revealed chlorophyll content increased significantly in tetraploids compared to diploids.
The results established a protocol of polyploid induction from scales of lilies in vitro, laying a foundation for the cultivation of new polyploid germplasm in lilies.
