Data set includes the raw data of results on biomass production (weight of roots, stems and leaves), gene expression (three genes) and nutrient concentration in leaves of hydroponic tomato plants.

Data show the results found in the evaluation of rootstocks, crop season and crop site or location on the Tahiti lime quality. As appareance is the most important trait for quality in the international market, this criteria was the response variable choosen. However different symptomatology can be identified in the external appearance of the fruit that can be triggered by either preharvest, or postharvest factors. In the current study, the effect of the location (Lebrija and Villavicencio), the rootstocks (Citromelo, Kryder and Volkameriana), the crop season (dry and rainy seasons) and the storage conditions (temperature and disinfection) on fruit quality were assessed. The relationship between the damage affecting the appearance and the evaluation factors were identified using a Pearson Chi-square statistical analysis. The best quality was observed in fruit from Lebrija, harvested in the dry season, disinfected, and stored at 10 °C. In the identification of the biological factors that affect the appearance of the Tahiti lime fruit, fungi developed during pre- and post-harvest phase were isolated, and strains of the genera Colletotrichum spp., Fusarium spp., Alternaria spp., Penicillium spp., Acremonium spp., Trichoderma spp., Curvularia spp., Phoma spp., Stachybotrys spp., and Ulocladium spp.,were identified.

Loquat (Eriobotrya japonica Lindl.) leaves are often used as herbal or folk medicines and applied into modern pharmacology. In this study, the effect of three shading levels (control/non-shading, monolayer netting, bilayer netting) and the duration (0-88 days) on leaf gas exchange, leaf mineral nutrients, ursolic acid (UA) and oleanolic acid (OA) accumulation of loquat trees, Xinbai1, were assessed. The results indicated that UA and OA production improvement can be up to 17.20% and 9.35% respectively during bilayer netting treatments compared with control trees. Besides, a series of mixed-effect linear models with treatments and its duration as random effects revealed that leaf transpiration within crown, Ca, P and K concentrations represented the most parsimonious combination for both UA and OA, consistent with the patterns in random forest regressions. Therefore, it emphasized that shading would be the potential cultural practices for high production of UA and OA through increasing foliar mineral nutrients.

Raw data Sixty flowering shoots of around 0.40 m length were collected from 60 trees that were randomly selected from two commercial orchards of ‘Fuji’ and ‘Gala’ apples in Prosser, Washington (USA). The king flowers were hand pollinated with ‘Red Delicious’ commercial pollen. Pollinated flowers were placed in growth chambers at eight constant temperatures of 4.5, 7, 11.5, 14.5, 21.5, 22.6, 28 and 30°C. At 12, 24, 48, 72 and 96 hours after pollination for lower temperatures, i.e., 4.5, 7, 11.5 and 14.5°C and at 4, 8, 12, 24 and 48 hours after pollination for the warmer temperatures, i.e., 21.5, 22.6, 28 and 30°C; pistils of tree flowers were detached and stored for one night in FAA (5% formalin, 5% acetic acid, 45% ethanol, 45% water: by vol.). The pistils were then washed and boiled for 30 minutes in a solution of sodium sulfite (50 g l-1) and then refrigerated. For evaluation the styles were detached from the ovary, rinsed with distilled water and placed in a water-soluble fluorescent solution of 0.1% Aniline Blue stain and 3.5 g l-1 of tribasic potassium phosphate for three days. Styles were then squashed between two microscope slides with a drop of fluorescent solution. The pollen tube length was measured as the distance between the pollen tube tip and the upper cell layer of the stigma, this process was carried out using a stage micrometer of 10 mm by 0.1 mm, 20X magnification and a fluorescence microscope. Response surface data Pollen tube lengths for each evaluated temperature were adjusted to logarithmic and logistic curves depending of the type of response as a function of the hours after pollination and the derivatives of the curves were calculated to determine the hourly growth rate of the pollen tube and the percentage of penetration of the pollen tube in the style (%) was calculated by dividing the adjusted pollen tube length from logarithmic and logistic curves by the average style length of the sampled flowers, 14.3 mm for ‘Fuji’ and 14 mm for ‘Gala.’ This data was used to fit a segmented nonlinear response surface for each cultivar to estimate the HGR as a function of temperature and style penetration.

These data are from two experiments conducted to determine the effect of seasonal thermoperiodicity on Camassia leichtlinii, Camassia quamash, and Toxicoscordion venenosum. Descriptions of the methodology used to collect this data can be found in the article, "Effects of Heat Treatment and Chilling Duration on Camas Growth and Development."

This file includes the raw data of the studies conducted about the effects of lemongrass oil application and modified atmosphere packaging on the postharvest life and quality of strawberry fruits.

In order to visualize the gestation behavior of the clusters according to the climatic factors studied (mean, maximum and minimum temperatures (ºC), Relative Humidity (RH%), Precipitation (mm) and Photoperiod (hours)), this worksheet shows the raw data used in the present study, from the average of 7 years of data collection that shows that in the periods of lower temperatures, low precipitation and photoperiod, the gestation time of the bunches increases.
