Cryopreservation for preservation of potato genetic resources
Cryopreservation is becoming a very important tool for the long-term storage of plant genetic resources and efficient cryopreservation protocols have been developed for a large number of plant species. Practical procedures, developed using in vitro tissue culture, can be a simple and reliable preservation option of potato genetic resources rather than maintaining by vegetative propagation in ge...
متن کاملStimulation of lettuce seed germination by ethylene.
Ethylene increased the germination of freshly imbibed lettuce (Lactuca sativa L. var. Grand Rapids) seeds. Seeds receiving either red or far-red light or darkness all showed a positive response to the gas. However, ethylene was apparently without effect on dormant seeds, those which failed to germinate after an initial red or far-red treatment. Carbon dioxide, which often acts as a competitive ...
متن کاملGenetic Analysis of Lettuce Seed Thermoinhibition
Seed thermoinhibition (inhibition of germination at warm temperatures) can reduce seedling emergence and stand establishment of cultivated lettuce (Lactuca sativa L.) when soil temperatures are warm (>25°C) at planting. Genetic variation for high temperature germination tolerance exists among accessions of lettuce and related wild species. Seeds of a L. serriola accession (UC96US23) germinated ...
متن کاملSkinner and Shive-lettuce Seed Germination3
germinated within 24 hours after prior exposure either to blue light or when maintained under complete darkness. However, far-red light augmented the germination of seeds pretreated with 6-benzylaminopurine so that nearly all such seeds germinated within 24 hours after treatment (table II). Far-red light also augmented the rate of germination of seed pretreated with a synergistic mixture of 6-b...
متن کاملOocyte Cryopreservation for the Elective Preservation of Reproductive Potential
Cryopreservation has been a technique used in reproductive endocrinology and infertility medicine since the early 1980s. Embryo cryopreservation, specifically, has been widely used in many in vitro fertilization (IVF) programs worldwide. This method has been well studied and is a common strategy employed for storing supernumerary embryos after IVF cycles, among other applications. Oocyte cryopr...
