“…Thus, efficiently and accurately distinguishing PR from other rhizome species is essential to assure product quality and consumer safety. The components of PR have particular characteristics, including time-consuming methods for breaking the dormancy [ 18 ] and growing the seedlings [ 19 ], as well as variable growth environments, all of which make classical identification techniques using herb morphology and biochemistry inefficient and often inaccurate. Therefore, other methodologies are required to effectively identify PR components and distinguish them from non-PR herbs.…”

DNA barcoding for the efficient and accurate identification of medicinal polygonati rhizoma in China

et al. 2018

Polygonati rhizoma (PR), a traditional medicinal and edible product with various bioactive components (Polygonatum polysaccharides, saponins, phenols, and flavonoids), is widely consumed in China. However, other species with morphological characteristics similar to those of the actual components are being used to replace or adulterate PR, causing issues with quality control and product safety. The morphological similarity of PR and its substitutes makes classic morphological identification challenging. To address this issue, DNA barcoding-based identification using ITS2 and psbA-trnH sequences was applied in this study to evaluate the efficiency and accuracy of this approach in identifying PR samples collected from 39 different regions in China. The identification of PR by this method was confirmed by other methods (phylogeny-based and character-based methods), and all the samples were clearly and accurately distinguished. This study highlights the efficient and accurate nature of DNA barcoding in PR identification. Applying this technique will provide a means to differentiate PR from other altered formulations, thus improving product quality and safety for consumers of PR and its products.

Having a variety of flower colors makes Schlumbergera truncata more valuable as an ornamental. S. truncata quality is mainly determined based on the number of phylloclades and flowering at the apical phylloclades. Cytokinins have been shown to promote branching and flowering in Cactaceae. This study was carried out to investigate the effects of growth regulators on the plant growth and flowering of four cultivars of S. truncata: 'Orange Candle', 'Pink Dew', 'Red Roman', and 'Snow Queen'. Foliar treatments of benzylamino purine (BA) or both a mixture of BA and gibberellic acid (GA 3 ) were applied (100 -200 mg•L -1 ) when plants reached the three-phylloclade stage under a long-day photoperiod. All plants treated with BA alone or the mixture of BA and GA 3 produced more phylloclades and branches than the control. Application of BA significantly produced more phylloclades and branches than BA in combination with GA 3 . However, BA application shortened the length of phylloclades, while adding GA 3 to BA promoted the elongation of phylloclades but delayed flowering. During the second trial, only BA was applied at 0 to 100 mg•L -1 to the plants at the two-phylloclade stage under a long-day photoperiod. The number of phylloclades increased by 19.8 -33.0% without shortening the length of phylloclades when BA was applied at 50 or 75 mg•L -1 concentration. The number of flower buds increased by 100 to 190% under short days when BA at 100 mg•L -1 was applied on 'Orange Candle' and 'Red Roman', while BA application at 150 -200 mg•L -1 increased only from 33.0 to 41.7% in 'Pink Dew' and 'Snow Queen'. The number of flower buds increased with the higher concentration of BA, but the number of days to flower decreased and the length of the flowers shortened. In conclusion, Only BA application appears to be more effective for increasing the number of phylloclades and flower buds in S. truncata.

Seed dormancy in ornamental plants: A review

Seed is the first input used in transfer of genetic traits in ornamental plants production. Seed dormancy is a physiological phenomenon in plants, which is caused by external or internal factors, and prevents seed germination, even in optimal conditions. Seed dormancy in flower crops impacts both seed production and germination. It can also complicate assessment of seed quality by the seed analyst who requires prompt germination to evaluate a seed lot. Flower crops display diverse mechanisms for seed dormancy like hard seed coat, immature, rudimentary embryo and inhibitors. It can be broken by soil melting and freezing, microorganism’s activity, forest fires, soil activity and being eaten by animals, in normal conditions. This review surveys and categorizes the different seed dormancy conditions found in flowering plants. Flower genera are listed according to dormancy type. Categories of dormancy include primary and secondary dormancy. Within primary dormancy, examples of flower genera can be found that display exogenous, endogenous and combinational dormancy. Secondary dormancy can be an important problem in selected flower seeds. Specific examples are given for each type of dormancy along with methods to alleviate dormancy.
