“…The reduced firmness of fruits that originated from treatments exclusively involving GA 3 application may be associated with the reduced lignin concentration resulting from the absence of seeds. Lignin provides a matrix for cellulose and hemicellulose polymerization within secondary cell walls, which collectively contribute to tissue rigidity and tensile strength (Dardick and Callahan, 2014). According to Cai et al (2006), fruit firmness increased during loquat (Eriobotrya japonica) ripening, showing a positive correlation with lignin accumulation in the mesocarp.…”

The biological function of fruiting is to produce and disseminate seeds. However, seedless fruits have some advantages, including the ease of consumption and the increased added value of the final product and fruit quality. The present study aimed to evaluate the combined use of gibberellic acid (GA 3 ) and hand pollination with Annona squamosa pollen grains on fruit set and the physical and chemical parameters of 'Gefner' custard apple fruits. The experiment was performed in a commercial custard apple orchard in a randomized design, with 11 treatments, four replications and five plants per parcel.

“…Peach fruit contains a large lignified endocarp, called a stone or a pit, at its center (Dardick and Callahan, 2014). The pit develops rapidly, starting immediately after fertilization and continuing through stage I of fruit growth.…”

Nondestructive Detection of Split Pit in Peaches Using an Acoustic Vibration Method

Split-pit in peach fruit is a problematic disorder. Split-pit fruit cannot be detected based on external appearance, and contamination of fruit by split-pit reduces its reliability in the marketplace. Here, we demonstrate that split-pit fruit can be identified by a nondestructive acoustic vibration method and a unique approach based on the ratio of the third (f 3 ) to the second (f 2 ) resonant frequency. The response-resonant frequency spectra showed that the peaks of f 2 frequencies in split-pit fruit were shifted to much lower values than those in normal fruit, whereas those of f 3 frequencies showed only small shifts. The calculated f 3 /f 2 ratios in most normal fruit were in the range of 1.35-1.4, whereas those in split-pit fruit were 1.45-2.0. Analysis of more than 300 fruit samples revealed that by setting the f 3 /f 2 cut-off value at >1.45, 95% of split-pit fruit in the fruit samples were detected, whereas only 1.5% of normal fruit were missorted as split-pit fruit. A model for simulating the vibration properties of peach fruit was developed by using the finite element method. The simulated vibration patterns showed that f 3 /f 2 values were increased by the insertion of split pit, indicating that, at least partially, the observed high f 3 /f 2 values in split-pit fruit directly reflected split-pit occurrence. These results clearly demonstrate that the use of f 3 /f 2 ratios obtained using an acoustic vibration method can effectively detect fruit with split-pit. The possibility of installing acoustic vibration devices in peach sorting lines and the application of portable devices to unpicked fruit on the tree are discussed.

“…The septum is connected to the inner walls of the valves at both sides through the replum. The replum, also known as false septum, is a thin layer separating the two valves of the silique along both sides, and it contains the main vascular bundles [55]. The valves are differentiated into several layers with During the silique dehiscence process, while endocarp a layer undergoes programmed cell death and starts to disintegrate, endocarp b layer goes through cell wall lignification [57].…”

In wild habitats, fruit dehiscence is a critical strategy for seed dispersal; however, in cultivated crops it is one of the major sources of yield loss. Therefore, indehiscence of fruits, pods, etc., was likely to be one of the first traits strongly selected in crop domestication. Even with the historical selection against dehiscence in early domesticates, it is a trait still targeted in many breeding programs, particularly in minor or underutilized crops. Here, we review of this trait in pulse (grain legume) crops, which are of growing importance as a source of protein in human and livestock diets, and which have received less attention iii) the molecular pathways underlying this important trait, iv) an overview of the extent of crop losses due to shattering, and the effects of environmental factors on shattering, and, v) efforts to reduce shattering in crops. While our focus is mainly pulse crops, we also included comparisons to crucifers and cereals because there is extensive research on shattering in these taxa.
