TL;DR: A new medium was formulated by comparing data from analysis of the main mineral elements found in the apical shoots and in mature embryos in olive and almond, characterized by a high content of Ca, Mg, S, Cu and Zn compared to almond, which is easy to propagate on MS medium.

TL;DR: Elyatem et al. as mentioned in this paper found that storing pomegranate fruits at 5°C or lower resulted in chilling injury to the fruits, and the severity of the symptoms increased with time and temperature-decrease below 5°c.

TL;DR: In the field, the concentration of red anthocyanin pigments in the skin increased up to 3-fold before and during commercial harvest as discussed by the authors, and this increase coincided with the start of rapid ethylene production in the apples.

TL;DR: This paper found that adding extra calcium to the nutrient solution increased the calcium concentration in the proximal, but not in the middle or distal, segments of the tomato fruit, supporting the hypothesis that a positive root pressure at night promotes transport of calcium into tissues and organs that have restricted transpiration.

TL;DR: Assimilate distribution in Cucumis sativa, cultivar ‘Farbio’, was studied during 36 days after emergence of the inflorescense in the 5th axil to formulate a hypothesis that relates the dynamics of fruit growth to assimilate supply and the sink activity of individual fruits.

TL;DR: Potential techniques for improving the setting and retention of fruit include varietal selection, withholding of nitrogen fertilization during flowering and early fruit growth (to reduce vegetative flushing), and the maintenance of plant moisture status (irrigation, overhead misting and windbreaks).

TL;DR: This system provides a rapid method for propagation of ‘Troyer’ citrange with direct formation of shoots from epicotyl segments and rooting of regenerated shoots in treatments containing 2.0 mg l−1 NAA alone.

TL;DR: Priming four seed-lots of leek cultivar ‘Winterreuzen’ in PEG solution significantly improved the rate and uniformity of seed germination, particularly in the slower-germinating lots, in both field and glasshouse conditions.

TL;DR: Germination of somatic embryos appeared to be enhanced by 1 mg l−1 benzyladenine (BA); however, most of the germinating embryos became embryogenic, and somatic embryogenesis was induced following sub-culture from MS medium with 2,4-D to MS without growth regulators and with or without activated charcoal.

TL;DR: In this article, P adsorption isotherms were conducted on 7 root media components or mixtures of components, including the 2 above-mentioned mixes, to determine the quantity of P adsorsbed to give 0.2 ppm in the soil solution.

TL;DR: Roots can be readily induced with IBA, but salt concentration and the physical support on which shoot-tips are grown influence both root initiation and growth, and half-strength salts and 1 μM IBA gave best root initiation.

TL;DR: In this paper, the effects of coating on the permeability of the fruit skin to chlorine were caused by stomatal blockage, which physically impeded gaseous diffusion.

TL;DR: Addition of phloroglucinol to the rooting medium enhanced both the percentage of shoots forming roots and the survival of plantlets after transplantation and about 30% of the plants raised in vitro were lost owing to a shoot-collapse which was not prevented by the application of fungicides.

TL;DR: Reducing the rate of fruit transpiration during the first week of storage by a pre-cooling treatment prior to low-temperature storage delayed, but did not eliminate, the development of chilling injury.

TL;DR: Although a silicone formulation had the greatest effect in reducing transpiration and water stress in transferred plants, it had the adverse effect of stunting plant growth and all other treatments with antitranspirants were ineffective in improving vigor and survival of plants compared to controls.

TL;DR: Inter- and intra-specific specificity was detected in the interactions of wild Cucumis species with both pathogens.

TL;DR: Enzymes of polyamine synthesis and, to a lesser extent, polyamine contents roughly followed patterns of growth activity in fruit tissues, with a maximum at the early stages, a minimum at mid-summer and intermediate values at full fruit development.

TL;DR: Flowering and early bearing of mango trees during the 1–4 years after planting suppress vegetative growth and the optimal time of GA 3 application depends on climatic conditions and cultivation practices.

TL;DR: Sterile cultures were obtained from expanding buds of Rhododendron cultivars ‘Pink Pearl’, ‘Nova Zembla’ and ‘Gomer Waterer”, and shoot production with liquid medium was 10-fold higher than with agarsolidified medium, which increased the number of roots produced per shoot.

TL;DR: The experiments have shown an interaction between root-zone temperature and light levels for greenhouse tomatoes, and caused large increases in shoot dry weight and fruit development when light was not limiting plant growth, but had deleterious effects on flowering and fruit set under shaded conditions.

TL;DR: Initiation and development of pistillate flowers in Actinidia chinensis Planch, cultivar ‘Hayward’ (kiwifruit, Chinese gooseberry) was followed using light and scanning electron microscopy and results indicate that dormant buds contain undifferentiated primordia in the leaf axils.

TL;DR: In this paper, the authors investigated the early stages of the development of the fruit set of the Citrus reticulata Blanco (C. reticulus) mandarin using gas chromatography.

TL;DR: Daily shrinkage of fruits was measured over a wide range of vapour pressure deficits of the air with potted apple trees cultivar ‘Cox's Orange Pippin’ and it was found that reverse flow of water to other parts of the tree was the main factor determining the degree of fruit shrinkage during the day.

TL;DR: It was concluded that water loss during dry cold storage is not the cause of the reduced vase life of cold-stored rose flowers.

TL;DR: In this paper, the role of Ca and Mg in the enzymatic browning of "Golden Delicious" apples was explored, and the results indicated that Ca is predominant in the prevention of this disorder, whereas a deficiency of Ca is involved in its induction.

TL;DR: The effect of day and night temperatures of 10, 14 and 18°C on growth and flowering under short days was studied with six cultivais of chrysanthemum, finding that a high day temperature resulted in earlier flowering and taller stems, but did not influence flower number and final total fresh weight.

TL;DR: The several cultural stages necessary before the plantlets raised from these embryoids could be transferred to soil are described and most of them did not produce viable seeds and many died during the winter.

TL;DR: In this paper, the authors measured the seasonal growth of three lettuce cultivars (Ostinata, Summer Bibb and Grand Rapids) in a greenhouse in a high-insolation desert environment and found that the best predictor of growth was the product of day temperature and the log of radiation.

TL;DR: High humidity had no effect on decay in cherries or peaches, but it significantly reduced weight loss and delayed the appearance of shrivel in peaches stored at 0°C, however, after storage at high humidity for 4 weeks, peaches ripened with low rates of C 2 H 4 evolution and showed severe low-temperature injury, slight peeling-injury and a poor flavour ex-store.

TL;DR: The expiants of leaves were excellent for regenerating many bulblets per expiant, while those of stems produced the heaviest bulblet, on average.
