In vitro germination of western larch pollen
Canadian Journal of Forest Research, 2000We have been able to successfully germinate western larch (Larix occidentalis Nutt.) pollen in vitro. Pollen was rehydrated at 100% RH for 16 h before being sprinkled on semisolid and liquid media. The basic medium contained Brewbaker and Kwack minerals diluted 1:10 and was supplemented with polyethylene glycol 4000 and three different concentrations ...

IN VITRO GERMINATION OF THREE OLIVE CULTIVARS
Acta Horticulturae, 2006Olive seedlings are used in breeding programs as well as rootstocks for grafting of hard-to-root cultivars. However, olive seed germination is not easy, low and slow germination rate are some of the persisted problems. In vitro germination of isolated embryos could be a useful method for increasing the efficiency of germination.

In vitro germination of black walnut pollen
Canadian Journal of Botany, 1971Black walnut pollen was germinated on liquid and agar-based media containing 20% sucrose, a requirement for germination and normal tube development. Boron (100 ppm boric acid) added to this medium slightly enhanced germination. Germination occurred only in dense (150+ grains/mm2) populations of pollen on the agar medium. This population effect was not

Precocious Germination of Tomato Embryos in vitro
Journal of Plant Physiology, 1989Summary Precocious germination of tomato ( Lycopersicon esculentum Mill.) embryos from self or intraspecific pollination was studied in an attempt to speed up breeding programs. Growth of embryos excised from fruits 2 weeks post-anthesis was slow. Three week old embryos developed into transplantable plantlets 3 weeks earlier than the time needed for

In Vitro Analysis of Cotton Pollen Germination
Agronomy Journal, 2004Crops with economically valuable reproductive structures show the greatest negative discrepancy between average and record yields. To alleviate environmental stress–related yield reductions, a better understanding of the relative sensitivities of pollen development, dehiscence, pollen germination, pollen tube growth, fertilization, and subsequent boll ...

1994
The ability to germinate fresh pollen on a “defined” medium offers opportunities for a number of areas of research. Applications, such as agrichemical assessment, gametophyte selection, etc., have been reported by a number of investigators over the last 25 years or more.

Germination in vitro of ryegrass pollen grains
Euphytica, 1973Pollen grains of diploid and tetraploid Italian, perennial and hybrid ryegrass (Lolium spp.) germinated on 20% sucrose solution with 10 ppm each of CaCl2, H3BO3 and EDTA. Pollen tubes emerged within 2–3 minutes after sowing and completed full growth within 1 1/2 hours. The tube elongation showed the expected linear growth rate. The tubes of the haploid

In vitro germination of wheat proembryos to fertile plants
Plant Cell Reports, 1994Wheat proembryos were excised 7 days after anthesis and germinated to normal fertile plants with an efficiency of 90%. These embryos had clearly differentiated shoot apical meristems and represent an interesting model system for studies of meristem biology.

In vitro conidial germination in Arthrinium aureum and Arthrinium phaeospermum
Mycopathologia, 2004This paper describes the microscopic details of conidial germination and the influence of pH, sodium chloride concentration, 3% glucose, 3% saccharose and ultraviolet irradiation on the conidial germination in Arthrinium species. Under laboratory conditions, germination started after an incubation period of 90 minutes in 2% malt extract broth at 25 ...
