Intestinal mucosal injury was classified using the Chiu's method (20): 0, normal intestinal mucosal villus; 1, cystic gaps appearing under the epithelium at the villus apex, with capillary hyperemia; 2, expanded cystic gaps under the epithelium, moderate edema in the lamina propria, and dilation of the central cheliferous vessels; 3, significant edema in the lamina propria, degeneration and necrosis of the intestinal mucosal epithelial cells, and abscission
of a few villus apex; 4, degeneration, necrosis, and exfoliation of the epithelial cells, abscission
of some villus, exposure of the lamina propria, capillary dilation, and hyperemia; and 5, abscission
of the villus, disintegration of the lamina propria, and bleeding or ulceration.
When I researched that process, I learned a technical term for the dropping: "abscission
environmental control, internal regulation and physiological responses of plants.
The other source of grain shattering is abscission
layer (Ji, 2006).
The changes in weather and daylight also trigger trees to produce a hormone that causes cells at the base of the leaves to develop an abscission
(or a cut).
Further, low temperature storage has also been known to promote ethylene production that further triggers floral abscission
and early senescence in tuberose.
In the Caatinga, there are woody species in which leaf abscission
occurs at the end of the rainy season, whereas other species maintain their leaves during the dry period, resulting in different tree species over time and space (MACHADO; BARROS; SAMPAIO, 1997; BORCHERT; RIVERA; HAGNAUER, 2002).
Floral peduncle 2-4.8 (6 in fruit) cm long, thick (in vivo), fistulous and pale yellow (in siccus), with a proximal and a distal constriction (likely functioning as abscission
The number of thermal units accumulated until the natural fall or abscission
of the fruits from the trees was 3,173[degrees]C for 203 days after the bud swelling (DAS).
Under normal growth conditions, the percentage of pod set varies from 20% to 40% (Kokubun, 2011), in a way that flowers with an abscission
tendency show slower growth (Huff & Dybing, 1980).
The fruits were evaluated for physicochemical parameters such as abscission
resistance, skin color, berry firmness, decay incidence, soluble solids, titratable acidity, weight loss, rachis and berry dry matter, and rachis browning.
Given that the goaf boundary abscission
rate of the high suction roadway side close to the return air roadway was low, no large amounts of channels are formed for gas transport; when the horizontal distance between the high suction roadway and the return air roadway is too large, the goaf caving rocks will be gradually compacted, the abscission
rate will be reduced, and goaf gas concentration will be decreased also.
