Phytohormones and candidate genes synergistically regulate …
2023年11月3日 · The fruit population of most plants is under the control of a process named “physiological drop” to selectively abort some developing fruitlets. However, frequent fruitlet abscission severely restricts the yield of Areca catechu .
Analysis of antioxidant response in pomelo fruitlets subjected to ...
2021年10月1日 · The microstructures of fruitlets were attributed to the postharvest loss of water, browning of the pericarp, and infection by pathogens, causing poor storability and low resistance to diseases of fruits (Lin et al., 2002). Lignin is the major polymer in the lamellae between adjacent cell walls (Novaes et al., 2010). We hypothesized that the ...
Apple Fruitlet Abscission Prediction. II. Characteristics of Fruitlets ...
2023年9月1日 · Abstract. Apple (Malus × domestica L. Borkh.) growers need tools to predict the efficacy of chemical thinners that are applied to induce fruitlet abscission to aid in crop load management decisions. Recently, reflectance spectroscopy-based models to predict fruitlet abscission rates were developed.
Biochemical and molecular aspects of fruitlet abscission
Fruitlet abscission during fruit development is due to the activation ofpre-differentiated abscission zones (AZs) located between twig andpedicel, and/or pedicel and pericarp. Major advances on biochemicaland molecular aspects are related to β-1,4-endoglucanase (EG) andpolygalacturonase (PG), two cell hydrolases involved in the cell ...
Early induction of apple fruitlet abscission is characterized by an ...
Apple (Malus domestica) fruitlet abscission represents an interesting model system to study the early phases of the shedding process, during which major transcriptomic changes and metabolic rearrangements occur within the fruit. In apple, the drop of …
PbrARF4 contributes to calyx shedding of fruitlets in ‘Dangshan …
2024年3月1日 · Fruitlet calyx shedding in pear plants is apparently regulated via numerous pathways that involve both environmental triggers and phytohormones cues such as auxin.
Signaling Pathways Mediating the Induction of Apple Fruitlet …
Sample fruitlets were labeled according to their size, position within the cluster, and eventual treatment (L, lateral; C, central; B, treated with BA; 1, small size; 2, medium size; 3, big size). In this study, BA treatments on apple trees were exploited to selectively induce drop of lateral fruits that usually persist and develop.
LcMPK3 and LcMPK6 positively regulate fruitlet abscission in litchi
2024年8月6日 · Consistently, the cumulative fruitlet abscission in LcMPK3-silenced and LcMPK6-silenced fruitlets was 60.1% and 62.7%, respectively, which were significantly lower than that in control (78.9%) (Fig. 3d), suggesting that both LcMPK3 and LcMPK6 act as positive regulators in control of litchi fruitlet abscission.
Selective Retention of Cross-Fertilised Fruitlets during ...
2024年6月5日 · We identified selective retention of cross-fertilised Hass avocado fruitlets because the percentage of retained progeny that were cross-fertilised more than doubled during fruit development, from 4.6% at 6 weeks after peak anthesis to 10.7% at fruit maturity (Table 2).
Signaling pathways mediating the induction of apple fruitlet ... - PubMed
Abstract. Apple (Malus × domestica) represents an interesting model tree crop for studying fruit abscission. The physiological fruitlet drop occurring in this species can be easily magnified by using thinning chemicals, such as benzyladenine (BA), to obtain fruits with improved quality and marketability. Despite the economic importance of this ...
