Human needs and concomitant commercial trade to date trigger the demand of new ornamental plants and new natural medicinal products. The current study includes preliminary seed germination trials and presents the development of effective vegetative propagation protocols for Lomelosia minoana subsp. minoana (Dipsacaceae) and Scutellaria hirta (Lamiaceae), both globally rare, local endemics of Crete (Greece) with potential ornamental and medicinal value. Based on material collected directly from the wild, seed germination was succeeded (38%, T50: 10.74) only for L. minoana subsp. minoana. The optimal indole-3-butyric acid concentrations for effective rooting of cuttings were 2000 mg L-1 for L. minoana subsp. minoana (85%) and 4000 mg L-1 for S. hirta (50%). Seasonal differences were observed in respective rooting rates of the studied taxa. The detected rooting rates for L. minoana subsp. minoana cuttings are above standards to allow possible commercial application in the ornamental industry. Although the detected rooting rate (50%) for S. hirta was adequate for its ex situ conservation, it seems almost marginal for future commercial application and further investigation is needed. The sustainable utilization of these Cretan endemics studied herein provides new input for the ornamental-horticultural and cosmetic-pharmaceutical industries. This study shows how rare and endemic wild plant species can be progressively domesticated and introduced into sustainable cultivation systems in order to avoid the depletion of unique phytogenetic resources.

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.

Seeds and scionwood of Malus sieversii Lebed. have been collected from wild populations of apple trees in Kazakhstan. Seedlings and grafted trees were planted in the orchards at the U.S. Dept. of Agriculture Plant Genetic Resources Unit in Geneva, N.Y. We developed core collections to capture the genetic and phenotypic diversity represented in the trees from each of two of the Kazakhstan collection sites. These core collections capture more than 90% of the genetic diversity of the original populations, as determined using seven unlinked simple sequence repeat markers and 19 quantitative traits. Since phenotypic evaluations of these materials have been completed, the 35 trees within each population will be used as parents in crosses so that the genetic diversity in the orchard populations can be captured as seed for long-term ex situ conservation. This strategy of storing seeds, rather than maintaining costly field collections, could be applied to other collections of wild plant materials in the National Plant Germplasm System.

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.

The continual search for new attractive ornamentals and innovative natural medicinal products is the main focus of floricultural and pharmaceutical industries worldwide. Aiming to introduce two new Cretan endemic species in the commercial trade, Acantholimon androsaceum (Jaub. & Spach) Boiss. and Limonium chersonesum Erben & Brullo (Plumbaginaceae) have been selected in the current study. These were derived from a total of 223 local endemic species and subspecies of Crete, which constitute an exceptional wild treasure of the Mediterranean flora. Prior to any commercialization, efficient massive propagation protocols are required. Although sexual propagation using seeds collected from the wild was unsuccessful for these two taxa, the results of vegetative propagation experiments were satisfactory. Wild plant material was used for cuttings in order to develop a reasonable and homogenous number of stock mother plants for propagation trials. As a result of experiments conducted in the current research, two vegetative propagation protocols were developed, which could be used commercially for the massive production of elite clonal plants of A. androsaceum and L. chersonesum. These protocols provide 71.43% successful rooting for A. androsaceum within 40 days, using 2000 ppm IBA, and 80.95% rooting for L. chersonesum within 30 days, using 1000 ppm IBA. This study is part of a strategy and research methodology aiming at the selection of new, rare and endemic native industrial crops for the ornamental and pharmaceutical sector, exploiting sustainably the rich phytogenetic resources of Crete.

Yuzammi. 2018. The diversity of aroids (Araceae) in Bogor Botanic Gardens, Indonesia: Collection, conservation and utilization. Biodiversitas 19: 140-152. Bogor Botanic Gardens is an ex-situ conservation centre, covering an area of 87 ha, with 12,376 plant specimens, collected from Indonesia and other tropical countries throughout the world. One of the richest collections in the Gardens comprises members of the aroid family (Araceae). The aroids are planted in several garden beds as well as in the nursery. They have been collected from the time of the Dutch era until now. These collections were obtained from botanical explorations throughout the forests of Indonesia and through seed exchange with botanic gardens around the world. Several of the Bogor aroid collections represent ‘living types’, such as Scindapsus splendidus Alderw., Scindapsus mamilliferus Alderw. and Epipremnum falcifolium Engl. These have survived in the garden from the time of their collection up until the present day. There are many aroid collections in the Gardens that have potentialities not widely recognised. The aim of this study is to reveal the diversity of aroids species in the Bogor Botanic Gardens, their scientific value, their conservation status, and their potential as ornamental plants, medicinal plants and food. The methods of the research include direct observation in the garden and nursery collections, analysis of the Gardens’ long-term registration database, as well as herbarium studies in both the Herbarium Bogoriense and the Gardens’own herbarium. A total of 130 species of aroids belonging to 36 genera have been cultivated in the Bogor Botanic Gardens. It is estimated that the gardens has 29% of the total number of genera in the world (21 genera are native to Indonesia). The aroid collection consists of terrestrial plants, aquatic plants and climbing plants (61 species, 12 species and 57 species, respectively). Amorphophallus paeoniifolius has developed further as a food plant. Genera such as Aglaonema, Alocasia, Apoballis, Rhaphidophora and Scindapsus have long been used as ornamental plants. Futhermore, some Homalomena species can be extracted for essential oils, while Epipremnum pinnatum has application in the treatment of cancer. Descriptions of some endemic, rare and high value species are discussed in this paper.

Abstract. Ribeiro KAF, Madeira de Medeiros C, Agudo JAS, Sánchez JS. 2019. Seed germination of Carex lainzii Luceño, E. Rico & T. Romero: An endemic Spanish endangered species. Biodiversitas 20: xxxx. Strategies to halt the decline of biodiversity include: in-situ and ex-situ conservation, the latter already considered at the global level essential in conservation programs. The results of the germinative responses of Carex lainzii Luceño, E. Rico & T. Romero (Cyperaceae), an endemic Spanish endangered species, are presented in this work, to different trials carried out in the laboratory with seeds harvested in the two known populations of that community. Treatments with and without 0.2% potassium nitrate (KNO3) were tested for four, six and eight months in cold stratification at 5 °C in two germination chambers at different temperatures (22/10 °C and 27/15 °C with a photoperiod of 12/12 hours). The results indicate that there is a large difference in germination rates between the two populations. The use of KNO3 did not increase germination rates in any case, but differences were found between periods of cold stratification, with six months being the most effective. On the other hand, the germination rates of both populations remain low (17.58% and 2%) compared to the obtained rate of seed viability. With this first approach to the understanding of the germination requirements of C. lainzii, it becomes clear that new essays are needed to obtain better results, in order to effectively implement the protection plans of C. lainzii populations.
