Objective: To understand the effect of illumination, temperature on the germination of the Prunella vulgaris seeds.
Method: The general germination method.
Result: Illumination showed no clearly effect on the germination rate of the P. vulgaris seeds under proper temperature condition; However, illumination was the main factor to determine the germination rate of the P. vulgaris seeds when the temperature condition was unsuitable. The germination rate of the P. vulgaris seeds decreased with the time and increased when the marinating time was from 12 to 36 hours. When temperature reached 5-25 9 degrees C, the trend of the germination rate increased at frst and then decreased.
Conclusion: The optimal germination condition of P. vulgaris seeds is 12 h of marinating time at the temperature of 20 degrees C under illumination.

Effective Microorganism (EM) is widely employed as a growth promoter in agricultural practices. The aging of oat seeds not only directly impairs agricultural production but also exerts adverse effects on biodiversity. The mechanism through which EM influence the germination of aging seeds remains unclear.

Roses are one of the most important flowers applied to landscape, cut flowers, fragrance and food industries widely. As an effective method for plant reproduction, the regeneration via somatic embryos is the most promising method for breed improvement and genetic transformation of woody plants. However, lower somatic embryogenesis (SE) induction rates and genotypic constraints impede progress in genetic transformation in rose.

(Orchidaceae) boasts high ornamental value due to its pleasant aroma, foxtail spike, and elegant floral morphology. Inducing to become tetraploid enhances horticultural traits and facilitates fertile intergeneric hybrids through crosses with other market-available tetraploid species. The experimental design involved the application of colchicine at varying concentrations-0.
