of Research 1. Evaluation of BBM BBM of the flight hardware was evaluated by repeated culture experiment under the simulated conditions for space experiment. As a part of device development, materials of a fixed container (an EPDM bag) and the fixation ability of the fixatives were also evaluated. After long term storage (> one month) in the EPDM bag gave little damage on the fixed specimens wh...
Firmly united conjugant pairs of P. caudatum were easily separated by treatment with trypsin, 0.025--1.0 mg/ml in 2 mM phosphate buffer at pH 7.2. Cytological observations showed that pairs separated by this means undergo normal meiosis and subsequent prezygotic divisions. Microspectrophotometric comparisons of G1 micronuclei in the parent with those in clones derived from prematurely separated...
BACKGROUND Outcrossing is known to carry genetic advantages in comparison with inbreeding. In many cases, flowering plants develop a self-incompatibility mechanism, along with a floral component adaptation mechanism, to avoid self-pollination and to promote outbreeding. Orchids commonly have a lip in their flower that functions as the a visiting plate for insect pollinators. Aside from the lip,...
The almond [Prunus dulcis (Mill.) D.A. Webb] is normally self-sterile, requiring orchard placement of pollinizer cultivars and insect pollinators. Honeybees are the primary pollinators utilized, but climate change higher frequency extreme weather events have reduced their availability to levels insufficient meet demands current anticipated acreage. incorporation self-fruitfulness may eliminate ...
