That difference is explained, likely, due to the high temperatures added to the flooding faced by the plants in the period of the present experiment, which provided an abrupt fall in three out of the four gas exchange parameters evaluated by the fourth day, where the plants underwent serious leaf abscission
, preventing the experiment continuity.
The reduction in the number of living leaves was due to the occurrence of larger leaf abscission
(Figure 2C) in the plants grown under the highest salinity concentrations evaluated (40 and 60 mM NaCl).
Soon a brownish abscission
zone becomes apparent at the base of the corollatube.
Harvest started 93 days after sowing, and lasted for 17 days, taking the appearance of abscission
zone in the fruit peduncle as a point of harvest.
It is interesting to highlight that, in the cultivation of 'pitombeira' seedlings, there was expressive leaf abscission
in the lower branches.
Critique: Original, imaginative, engaging, entertaining, "The Abscission
Zone" by Samuel Muggington is a compelling science fiction novel that reveals the fragility and savagery of the natural world, along with mankind's profound impact on the Earth's biodiversity and ecosystems.
Most of the postharvest losses on table grapes are related to the berry abscission
and stem browning that affect the product appearance, reducing its commercial value and becoming a problem to table grapes production chain worldwide.
Nevertheless, the biophysical process is always the same: the cell membrane deforms and reshapes to wrap around the particle, and upon closure and abscission
of the resultant cup, the particle is internalised.
It is also suggested that abscission
may cause retardation in seed yield.
It is a high yield plant with a complete abscission
layer originating from Oryza sativa L.
1997), increase the content of inhibitors like abscisic acid in the leaves and decreased the auxins content (Anisimov and Bulatova, 1982) leading to fruit abscission
at the reproductive stage (Zhao and Oosterhuis, 2000) so that senescence started at early growth stages.
This central spindle signal model is based on the activity of two key regulatory complexes required for central spindle assembly, Rho regulation, abscission
, and, ultimately, successful cytokinesis.
