Verbascum yurtkuranianum is a narrow endemic species occurring in a single location, the northern Bursa province (Turkey). It is an endangered and potentially ornamental plant. No conducted study on its life and biology, production, and aesthetic features is available. This study aimed to reveal its vegetative properties, seed characteristics, methods and requirements for seed germination, germination speed, and potential ornamental value so it can be conserved ex situ and produced. Verbascum yurtkuranianum has potential value as an ornamental plant regarding its aesthetic features as a flower. This study revealed that the total number of individuals in the species is 788. Without any treatment, 70.7% germination rate is achieved if the seeds are stored at 4 °C. The optimum germination temperature was from 15 to 20 °C (77.3% and 78.7%, respectively), and the photoperiod regulation for seed germination was 12/12 or 8/16 (light/dark) hours (74.7% and 76.0%, respectively). The most effective treatment to promote germination rate was found by implementation of 60 min ultrasonic waves (94.3%) or application of 120 min vacuum (95.3%). Germination occurred between 8 and 10 days. A parcel of ex situ conservation was constituted with the seedlings obtained from the germination studies.

In this study, we observed the flowering phenology, breeding system, pollination and seed germination of four species of Calligonum (C. calliphysa, C. rubicundum, C. densum and C. ebinuricum) in the Turpan Eremophytes Botanic Garden, China. Our results showed that the species had overlapping flowering phenologies and were pollinated by similar pollination agents. Their breeding systems were self-compatible, and with signs of outbreeding, but not of hybridization with each other; the main isolation mechanism was post-zygotic isolation and they also had high seed germination rates. Therefore, they are suited to ex situ conservation in the Turpan Eremophytes Botanic Garden, and can supply sufficient seeds for renewal populations and the conservation of germplasm resources. Furthermore, these results provide theoretical support for the construction of a national germplasm resource garden of Calligonum, and for the introduction to the garden of other eremophyteplants and their conservation.

Abstract Urban forests are responsible for a lot of benefits, and can be used as a tool to ex-situ conservation of native species. Our study investigated a public urban forest aiming to provide subside to management projects in order to allow the accurate fulfillment of social, aesthetic and ecological functions displayed by trees. Our survey was conducted in 6 public squares and 5 gardens in the Jardins neighborhood. We classified the trees according to their phytogeographic origins and seed dispersal habit. The Shannon-Weaver (H’) index, Simpson’s dominance (D’) and Pielou’s equability (J) were determined. A total of 507 individuals were sampled, located in 12 botanical families and 29 species, and 13 of them were classified as native and 16 as exotic. The family with higher species richness and number of species was Fabaceae (36%). Regarding the seed dispersal syndrome, the most representative was zoochory (52%). The ecological index showed medium species diversity (H’=2.2284), high dominance (D’=0.7899) and medium number of individuals (J) 0.6552. Although the Jardins neighborhood was planned, the urban forest in this area still needs improvement; such as incentive measures that can promote biodiversity and the application of ex-situ conservation.

The Aesthetic

Lapiedra martinezii Lag. (Amaryllidaceae) is an autumn-flowering geophyte that grows in coastal and sublittoral environments. The interests on this species has come out during the last decades due to its content in bioactive alkaloids and its conservational status. The aim of this work was to review the available information on L. martinezii and to assess whether it could be introduced as ornamental plant in xero-gardening. Therefore, the aesthetic traits were analyzed and compared to other cultivated and wild plants. Also, information on its ecological and propagation requirements were checked to discern whether it could be adapted under different production systems and culture conditions. In addition, other aspects were also analyzed to identify strengths and limitations of this species for its further revalorization as ornamental plant. The results obtained suggest that L. martinezii could be a good choice as foliage plant to grow it on gardens as an alpine bulb or pot plant. Moreover, it might be quite well adapted under different production and culture conditions in dry and semi-arid regions. The horticultural traits related to its germination and in vitro multiplication are interesting strengths to bear in mind for its industrial propagation and early domestication. Finally considered, the introduction in xero-gardening could also help in its ex-situ conservation. However, a more-in-depth research would be needed to finally introduce it in the ornamental plants’ market.

Optimal Mode

Hedysarum grandiflorum samples were collected from 7 natural populations of the Volgograd, Samara and Lugansk People's Republic and the features of seed reproduction were studied under ex situ and in vitro conditions. The optimal temperature for seed germination and the dependence of germination and seed vigor on the storage were revealed. We observed the maximum germination rate in the scarified seeds of H. grandiflorum of 2018 collection and it was equal to 70%.It was found that the seed germina-tion and seed vigor are low and quickly decrease with years of storage, while their scarification allows to increase these indicators. It is noted that the relatively low germination of the studied seeds is leveled by the rather high productivity of species in general. The optimal mode of sterilization of H. grandiflorum seeds was experimentally determined - 10% Lysofornin® 3000 solution for 5 minutes. The percentage of sterile seedlings was 60%.

Moringa concanensis Nimmo. ex Dalz. & Gibs. is rare economic important plant distributed in Indian desert. Plant parts are used for different medicinal purposes. Present study was conducted to assess its status in nature as well as different seed germination treatment for its ex-situ conservation. Study revealed that germination was 100% in coco-peat media while, it was 97.56% in polythene bags. Seedling mortality was more (39.46%) in coco-peat media. After transplantation seedlings showed 82% survival in field.
