A biological specimen (also called a biospecimen) is a biological laboratory specimen held by a biorepository for research. Such a specimen would be taken by sampling so as to be representative of any other specimen taken from the source of the specimen. When biological specimens are stored, ideally they remain equivalent to freshly-collected ...
Typical information linked to a specimen would be the specimen's origin and when it arrived at the biorepository. (ii) Processing of specimens is standardized to minimize variation due to handling. Processing may prepare the specimen for long-term storage.
Plant collecting is the acquisition of plant specimens for the purposes of research, cultivation, or as a hobby. Plant specimens may be kept alive, but are more commonly dried and pressed to preserve the quality of the specimen. Plant collecting is an ancient practice with records of a Chinese botanist collecting roses over 5000 years ago. [1]
Few varieties are resistant to the disease and none are immune, so rotating susceptible plants with non-susceptible ones like cereals is a practice positive to limiting soft rot infection. The control of specific insect vectors is also a good way of controlling disease spread in the field and in storage.
Seeds are often considered as an important delivery system of genetic information. Cryopreservation of recalcitrant seed is the hardest due to intolerance to low temperature and low water content. [52] However, plant vitrification solution can solve the problem and help recalcitrant seed (Nymphaea caerulea) cryopreserve. [53]
For some plants it may prove helpful to allow the fresh specimen to wilt slightly before being arranged for the press. An opportunity to check, rearrange and further lay out the specimen to best reveal the required features of the plant occurs when the damp absorbent sheets are changed during the drying/pressing process.

That functionality can roughly be divided into five laboratory processing phases, with numerous software functions falling under each: [2] (1) the reception and log in of a sample and its associated customer data, (2) the assignment, scheduling, and tracking of the sample and the associated analytical workload, (3) the processing and quality ...
Harmful plant strategies – implementing existing methods and developing new technologies for the identification, exclusion, eradication, and management of invasive weeds and regulated plants. Biological control – developing technologies to allow natural enemies to effectively mitigate the impacts of invasive pests, arthropods, weeds, and ...
