“…Consequently, seeds would remain non-germinated in the soil until spring when temperatures are relatively low and snow melt and rainfall decrease salinity. Spring germination also has been documented in other desert-inhabiting Brassicaceae such as Alyssum minus (Sun et al, 2012), Diplotaxis harra (Tlig et al, 2008) and Farsetia aegyptia (Bhatt et al, 2018).…”

Effects of water stress and NaCl stress on different life cycle stages of the cold desert annual Lachnoloma lehmannii in China

For a plant species to complete its life cycle in arid and saline environments, each stage of the life cycle must be tolerant to the harsh environmental conditions. The aim of the study was to determine the effects of water stress (water potentials of-0.05,-0.16,-0.33,-0.56,-0.85 and-1.21 MPa) and NaCl stress (50, 100, 200, 300, 400, 500 and 600 mmol/L NaCl) on seed germination percentage, seedling survival and growth, juvenile growth and plant reproduction of Lachnoloma lehmannii Bunge (Brassicaceae), an cold desert annual that grows in the Junggar Basin of Xinjiang, China in 2010. Results indicated that low water stress (-0.05 and-0.16 MPa) had no significant effect on seed germination percentage. With a decrease in water potential, germination percentage decreased, and no seeds germinated at-0.85 and-1.21 MPa water stresses. Germination percentage of seeds was significantly affected by NaCl stress, and higher germination percentages were observed under non-saline than saline conditions. An increase in NaCl concentrations progressively inhibited seed germination percentage, and no seeds germinated at ≥400 mmol/L NaCl concentration. Non-germinated seeds were transferred from both PEG (polyethylene glycol-6000) and NaCl solutions to distilled water for seed germination recovery. The number of surviving seedlings and their heights and root lengths significantly decreased as NaCl stress increased. About 30% of the plants survived and produced fruits/seeds at 200 mmol/L NaCl concentration. Thus, seed germination, seedling establishment and reproductive stage in the life cycle of L. lehmannii are water-and salt-tolerant, with seedlings being the least tolerant. These tolerances help explain why this species can survive and produce seeds in arid and saline habitats.

“…Ex situ seed conservation is an effective way to safeguard threatened plants from extinction (Teixido et al 2017), and it is a practical way to preserve large amounts of genetic material in a small space with minimum risk of damage. Further, information on seed storage behaviour is needed to determine whether seeds stored in genebanks remain viable, because seed viability and germination are key factors in the success of restoration efforts, especially when stored seeds are used (Bhatt et al 2018).…”

Lilium polyphyllum D.Don ex Royle is a critically endangered medicinal herb of Himalaya. Seeds have epicotyl morphophysiological dormancy, and in the field a minimum of 34 weeks is required for root emergence. To date, treatments to decrease the time for root protrusion and seed storage behaviour have not been determined. We evaluated the effects of plant growth regulators and nitrogenous compounds as well as seed scarification on root emergence, and determined the storage behaviour of seeds. Root emergence at 20 °C was significantly increased by 100 ppm of indole butyric acid (IBA), KNO3, and thiourea, and by the application of NaOCl solution for 30 min. The mean germination time was significantly decreased by 50 ppm of gibberellic acid (GA3; 28 days) compared with 100 ppm GA3 (36 days). After 12 months of dry storage, the viability of seeds (TTC method) at room temperature (10–35 °C), 0–4 °C, and −20 ± 1 °C was 95%, 100%, and 100%, respectively; thus, the seeds have orthodox storage behaviour. Our recommendation for seedling production is to store the seeds at room temperature until they can be sown under warm wet conditions. Roots emerge after about 8 weeks, and then seeds should be given a 2-week cold moist treatment to break shoot dormancy. After 2 weeks of cold, transfer the seeds to warm (20 °C) spring temperature conditions to promote growth.

This report is based on extensive literature search to reveal the elements of animal and plan biodiversity in the State of Kuwait, and points out missing information on other little-known groups. Despite its small area, Kuwait enjoys a rich fauna, given its desert and marine habitats. Hundreds of published scientific papers and reference books were reviewied to amass all species, fauna and flora, that were reported from Kuwait. Conservation status for several groups according to the IUCN listing are included.
