“…Frequency of cell division is critical to fruit morphogenesis in a variety species such as Tomato [30][31][32][33], melon [37], pumpkin [35], cucumber [36][37][38][39]. In present study, we found that the fruit tip shape in 186 cucumbers inbred lines also were a complex trait and exhibit significant variations with angle range from 99 to 173° and fruit tip index range from 1.4 to 3.5.…”

BackgroundThe shape of fruit tip is critical to appearance quality and commodity value of cucumber (Cucumis sativus L.). Although diversity of cucumber fruit tip is rich, the genetic basis and molecular mechanism were poorly understood. In this study, the morphological and histological features of fruit tip were investigated to accurately evaluate the diversity in cucumber germplasm. QTLs of fruit tip were genetically mapped by using F 2 and RILs populations. Candidate genes of major-effect QTLs were predicted. ResultsThe appearance of cucumber fruit tip was generally divided into sharp, oval-round and blunt-round categories, but morphological measurement showed that the angle of fruit tip was continuously distribute in range of 99~173° and the fruit tip index (the ratio of diameter and length of tips) was in range of 1.4~3.5. Histological analysis suggested that the different structures of fruit tips were owed to the different distribution of cell number in vertical and horizontal direction, rather than difference in cell size. In total, thirty fruit tip related QTLs were identified from two mapping populations including a F 2 population derived from EC1 (blunt round tip) × 8419s-1 (sharp tip) and a RILs population derived from IL52 (oval round tip) × CCMC (sharp tip). Two major-effect QTLs were detected, of which Ft4.

“…The fresh mass of pericarp represents 80% of the total fruit fresh mass (data not shown; no impact of nitrogen supply) at maturity (from green mature stage to harvest). Sugars are the main driver of fruit growth by increasing osmotic pressure leading to water influx [64,65]. Their partitioning within the fruit is important to ensure cell division and cell growth, first in the inner part, then in the pericarp.…”

Precision horticulture is fundamental to ensure high quality production with a minimalenvironmental footprint. It offers the possibility to manage climatic and fertilization inputs closerto the plant needs. In practice, there is a tendency to over‐fertilize, as nitrogen limitation candecrease photosynthesis and consequently fruit yield, but also because nutrient recycling does notlead to any substantial costs increase, thus ignoring the influence of nitrogen input on the balancebetween growth and metabolism. Nitrogen recommendation for tomato greenhouse production onrockwool is 16mM, even it is well established that only 50% of nitrogen amount is really absorbedby plants. This study compares the usual practice (16 mM) to a nitrogen supply to meet plant’sneeds (5 mM). We analyzed plant growth and development, yield, leaf photosynthetic activity andfruit quality (sugars, acids, vitamin C,) over the entire crop period (December to October).Over‐fertilization favoured the accumulation of nitrogen in leaves and stem but yield, leafphotosynthetic activity and plant architecture were not significantly improved. In addition, itdecreased the quality of the tomatoes as the sugar:acid ratio decreased dramatically in the pericarp,whereas the locular gel composition remained similar. A reduction of the nitrogen supply is onesolution to improve tomato quality without any reduction of yield in greenhouse. These data haveto be incorporated in tomato fertigation management to define a new standard based on overallquality of tomato fruit and low environmental footprint.

“…This development period (to second and tenth week) is depends on the longitudinal growth path of the fruit (ten Hoopen et al 2012, Sheng & Maisin 2012, when cells are in mitotic activity and lack cellular differentiation. During that initial phase of fruit development, the orientation of the lignin fibers (Agrios 2005, Lira 2007, Keegstra 2010, Fanwoua et al 2013, the lack of polymers consolidation in the cell wall, and the exudate produced (Filonow 2002, Zelinger et al 2006, Rodríguez-López et al 2013, can promote conidia germination of Moniliophthora roreri on the fruit surface.…”

Background: The three-main cacao (Theobroma cacao) varieties cultivated in México are: Criollo, Forastero, and Trinitario. Each variety has a different fruit setting time and has been subjected to several selection stages. The aim of this study was to determine the susceptibility of the three cacao varieties to Frosty pod rot caused by Moniliophthora roreri. We also analyzed the physicochemical properties of the pericarp of the three varieties and its domestication age.Question: Is there a relationship between the degree of domestication of the cacao variety and its susceptibility to Frosty pod rot?Studied species: Theobroma cacao fruits.Study site: A cacao plantation in Chiapas, Mexico.Methods: The content of moisture, lignin, phenols, peroxidase activity and hardness of the pericarp were analyzed in the middle zone of healthy fruits at 4, 8 and 12 weeks of development. Number of healthy and infected fruits were recorded every week.Results: The highest susceptibility to Frosty pod rot was found in the immature stage of fruits from the Criollo variety. The disease was mostly found in the mid-zone of the fruit. The Criollo variety was the most susceptible. This variety showed the highest moisture values and the lowest values of the other measured parameters.Conclusions: The finest cacao is obtained from the Criollo variety, the one with the highest degree of domestication, and also the most susceptible to frosty pod rot. We suggest using material from wild Criollo populations and from the Forastero and Trinitario varieties in future breeding and selection programs.
