The genus Adenium has been held to contain as many as twelve species. These are considered by other authors to be subspecies or varieties. A late-20th-century classification by Plazier recognizes five species. [5] Species [3] Adenium arabicum Balf.f. = Adenium obesum; Adenium boehmianum Schinz - (Namibia, Angola) Adenium multiflorum Klotzsch.
Seed enhancement is a range of treatments of seeds that improves their performance after harvesting and conditioned, but before they are sown. They include priming, steeping, hardening, pregermination, pelleting, encrusting, film-coating, tagging and others, but excludes treatments for control of seed born pathogens .
It is a measure of germination time course and is usually expressed as a percentage, e.g., an 85% germination rate indicates that about 85 out of 100 seeds will probably germinate under proper conditions over the germination period given. Seed germination rate is determined by the seed genetic composition, morphological features and ...
Adenium obesum, more commonly known as a desert rose, is a poisonous species of flowering plant belonging to the tribe Nerieae of the subfamily Apocynoideae of the dogbane family, Apocynaceae. [3] It is native to the Sahel regions south of the Sahara (from Mauritania and Senegal to Sudan ), tropical and subtropical eastern and southern Africa ...
In addition to the mentioned seed pretreatments, seed germination is also assisted when a disease-free soil is used. Especially when trying to germinate difficult seed (e.g. certain tropical fruit), prior treatment of the soil (along with the usage of the most suitable soil; e.g. potting soil, prepared soil or other substrates) is vital.
Before the operation of a conventional seed drill, hard ground has to be plowed and harrowed to soften it enough to be able to get the seeds to the right depth and make a good "seedbed", providing the right mix of moisture, stability, space and air for seed germination and root development.
Adenium arabicum is a species of succulent plant commonly used for bonsai and cultivated for its shiny leaves, growth form and flowering characteristics. Common names include desert rose, elephant's foot, and Adan bush. [1] They are monoecious and self-sterile. [2] A. arabicum is native to Yemen and Saudi Arabia.
Gilbert White used hot beds warmed by manure to germinate melon seeds in England. [1] A seed germinator is a device for germinating seeds. Typically, these create an environment in which light, humidity and temperature are controlled to provide optimum conditions for the germination of seeds. One type of germinator is the Copenhagen or Jacobsen ...
