Apple fruit nonstructural carbohydrates and abscission as influenced by shade and terbacil
The theory that fruit abscission may be the result of a reduction in metabolites available to the young fruit was addressed by this study. Shade cloth or terbacil, a photosynthetic inhibitor, were applied to limbs and whole trees to examine the influence of treatment and time of application on …

Evaluating the importance of root abscission versus efflux to plant N-loss: consequences for plant N-isotope composition
… plant δ¹⁵N has not been suggested, although root abscission is likely to be more ubiquitous than N efflux. This thesis questions the extent to which N efflux and root abscission contribute to plant N-loss and plant δ¹⁵N values. I hypothesized that: (1) plants supplied with more N would have more …

Investigation of Regulatory Mechanisms of Chemical-Mediated Fruit Thinning in Apple (Malus X Domestica Borkh.)
… (1-MCP) on young apple fruit abscission, leaf and fruit ethylene production, and the expression of genes related to ethylene biosynthesis, perception and cell wall degradation were examined in "Golden Delicious" apples (Malus x domestica borkh.). NAA at 15 mg·L-1 and shading …

Factors Affecting Preharvest Fruit Drop of Apple
… information about cellulase activity in the abscission zone, effects of applied auxin and ethylene biosynthesis inhibition on drop, changing sensitivity to abscission induction during the season, and relationships among seed number, fruit weight, and day of drop. Observational studies were …

Regulation of The Escrt Function of Alix
… that performs membrane invagination and abscission. ALIX is a widely expressed adaptor protein that is critically involved in three classical ESCRT-mediated processes, including MVB (multivesicular body) sorting, cytokinetic abscission and retroviral budding. Previous studies have …

Improvement of asexual propagation and Anisogramma anomala detection protocols to facilitate applied breeding of new Corylus avellana and C. americana x C. avellana germplasm
… however, variable root induction rates and bud abscission among traditional Corylus cultivars currently limit this approach. A recent study suggests use of ethylene-blocking compounds in combination with low auxin levels may help overcome these challenges. Presently, the efficacy of these …

Organic carbon dynamics of the Neches River and its floodplain.
… swept from the floodplain trees prior to normal abscission in the fall. A continuum of leaf breakdown rates was observed in three common floodplain species of trees: Sapium sebiferum, Acer rubrum, and Quercus laurifolia. Leaves collected from blowdown as a result of Hurricane Rita did not break …

Compensation of Cotton to Square Removal at Various Rates
Fruit abscission is a natural occurrence in cotton. Fruiting retention is very important since yields are highly correlated with number of bolls produced. There are many factors contributing to the abscission of squares by cotton, including environmental conditions, heavy boll load, diseases, and …

Physiological and nutritional changes in nitrogen fixing trees associated with autumnal senescence and chilling
… nitrogen (N) from leaves prior to autumnal leaf abscission than the non-fixing species, sycamore and leguminous honey locust. Site had little effect on the net change in foliar N or P. Root bark seemed to be an important storage site for P during autumn in the dinitrogen fixing species as were …

Plant Growth Regulator Sprays and Girdling: Potential Horticultural Techniques to Increase Fruit Retention and Yield of Longan (Dimocarpus longan Lour.) Trees in California
… retention and yields are low due to excessive abscission during early fruit set. Horticultural techniques, such as plant growth regulator (PGR) sprays and girdling, often increase fruit retention and yield of fruit tree crops, though effects are typically dependent on treatment timing and PGR …

Characterization of 16B09 and 2D01 effector proteins in cyst nematodes
… receptor kinase that controls floral organ abscission and lateral root emergence, and is expressed in the nematode feeding cell, was identified as a potential host target of this effector.

Calcium and magnesium requirements of Ilex crenata Thunb. "Helleri"
… a discoloration of the lower leaves followed by abscission. A third experiment was performed on 'Helleri' holly growing in pine bark. Calcium was supplied at 0 and 120 ppm and Mg at 0 and 60 ppm. No differences in dry weight were observed. A third experiment studied the influence of four …

The Floral Biology of Argemone Aurantiaca Ownbey and Argemone Albiflora Hornem Subsp. Texana Ownbey
… petals as well as the yellow stamens undergo abscission. In the populations studied, Hymenoptera (e.g. Dialictus and Halictus) and Coleoptera (e.g. Euphoria and Lytta) were the most abundant and effective pollinators. Observations have revealed that Hymenoptera are effective cross-pollinators …

The role of cell division during tissue morphogenesis
… model to investigate the role of cytokinesis and abscission during de novo lumen formation. The cytokinetic bridge places at the center of the developing KV rosette, where it acts as a landmark for Rab11-mediated vesicle trafficking to bring polarity components such as CFTR to the site of future …

Weed-soybean canopy apportionment as an estimation of soybean (Glycine max) development and yield loss
… Soybean leaf area, mainstem node development and abscission were reduced as much as 10 percent in plants growing within 20 cm of the weed base; these reductions were not well correlated with final soybean yield. The mean yield of all soybean plants growing within 100 cm of the weed base varied …

The use of natural pressurised forced ventilation in plant micropropagation
… have been promoted and leaf and flower bud abscission have been reduced. In cauliflower, tobacco and Annona the leaf chlorophyll contents, rates of photosynthesis and yields were improved by this forced ventilation. These beneficial effects have been variously attributed to the efficient …
