Abstract: A process of priming mature, imbibed, germinated somatic embryos of a conifer species. The process comprises fully immersing mature, imbibed, germinated somatic conifer embryos in a sterile liquid nutrient medium, bubbling an oxygen-containing gas through the liquid nutrient medium containing the germinants to form an aerated embryo-containing nutrient medium, optionally exposing the aerated germinant-containing nutrient medium to light, at least intermittently, continuing the immersion, bubbling and optional exposure to light for a period of time effective to produce at least some successfully primed conifer germinants that are adapted for subsequent planting and conversion to viable seedlings, and removing the successfully primed conifer germinants from the nutrient medium.

Abstract: A new and distinctive variety of a slash pine tree which has been denominated varietally as ‘CP PS1-3352’ which is distinguished by high growth rate, good resistance to fusiform rust and pitch canker, excellent stem straightness, medium crown width, long stem internodes, flat to medium branch angle and medium branch diameter

Abstract: A new and distinctive variety of a loblolly pine tree which has been denominated varietally as ‘CF Q7766’ which is distinguished by great resistance to fusiform rust and pitch canker, exceptionally high growth rate, excellent stem straightness, distinctive very long internodes, narrow crown.

Abstract: A new and distinctive variety of a loblolly pine tree which has been denominated varietally as ‘CF L3791’ which is distinguished by high resistance to fusiform rust and pitch canker, excellent stem straightness, medium to wide crown width, few whorls to medium number of whorls, and very fast growth.

Abstract: Media and methods are provided for developing plant embryos utilizing low levels of a metabolizable carbon source, generally less than one or two percent. Within certain variants, the invention further subjecting the embryos to water stress during development. The media of the invention comprise less than about 2% of a metabolizable carbon source in combination with sufficient non-permeating osmotica to effect water stressing.

Abstract: A method for promoting maturation and development of vigorous conifer (gymnosperm) somatic embryos comprising the use of S(+)-ABA as the substantive form of ABA.

Abstract: A new and distinctive variety of a loblolly pine tree which has been denominated varietally as ‘CF Q3802’ which is distinguished by distinctive genetic fingerprint, high resistance to fusiform rust, outstanding stem straightness, long internodes and distinctive narrow crown with slender branches, and extremely fast growth.

Abstract: A method of sowing a somatic plant embryo or germinant of a conifer species to facilitate subsequent development of the embryo or germinant into an autotrophic seedling. The method involves the following steps carried out ex vitro in non-sterile conditions: providing a nutrient medium comprising particles of a solid component present within a flowable or semi-solid component containing water and a carbohydrate nutrient for the embryo or germinant, dispensing a quantity of the nutrient medium onto a surface of a porous solid growth substrate for the somatic plant embryo or germinant, and contacting the plant embryo or germinant with the nutrient medium. The nutrient medium has a fluidity such that at least some of the flowable or semi-solid component containing the carbohydrate nutrient remains in contact with the embryo or germinant at least until the embryo or germinant establishes vigorous growth under environmental conditions effective for such growth.

Abstract: The selection and isolation of mature somatic conifer embryos has previously involved chemical based or labour intensive techniques. Disclosed are simple yet highly effective methods to sort somatic embryos according to maturity to generate a population of quality somatic embryos that exhibit a high probability of successful conversion and germination. The methods include liquid sorting of somatic embryos using an aqueous liquid having a specific solute concentration and/or a viscosity. In this way, embryos that have attained a degree of maturity (and preferably desiccation tolerance) can be separated both from embryos that are comparatively immature and importantly from significant quantities of proliferation material and other organic matter generated during embryo propagation.
