| Temperature is a major factor that affects metabolic processes in living organisms. Thermal time has been widely used to account for the effects of temperature on crop growth and development. However, the thermal time approach has been criticized because it assumes a linear relationship between the rate of crop growth or development and temperature. The response of the rate of crop growth and development to temperature is nonlinear. The objective of this study was to develop a generalized nonlinear temperature response function for some growth and developmental parameters in kiwifruit (Actinidia deliciosa (A. Chev.) C. F. Liang & A. R. Ferguson). The nonlinear function has three coefficients (the cardinal temperatures), which were 0ºC, 25ºC, and... |

| The effect of foliar boron treatments on fruit growth and seed development in Actinidia deliciosa, cv. Hayward, was studied. The distal leaves (BH) or fowers (BF) of a shoot were sprayed with 500 mg L-1 boric acid during the fowering period. The mobility of boron from the leaves to the fowers through the phloem was determined by spraying only the leaves. From 0 to 96 h after treatment, leaves and fowers were sampled and total boron was assessed. At harvest time, fruit weight and diameter plus seed weight and number were measured for the different treatments. The weight of fruits growing from shoots with boron-treated leaves were 14.1% higher than the control, while the weight of fruits derived from boron-treated fowers was 17% higher than that of fruits... |

| The effects of plant growth promoting rhizobacteria (PGPR) on the rooting and root growth of semi-hardwood and hardwood kiwifruit stem cuttings were investigated. The PGPR used were Bacillus RC23, Paenibacillus polymyxa RC05, Bacillus subtilis OSU142, Bacillus RC03, Comamonas acidovorans RC41, Bacillus megaterium RC01 and Bacillus simplex RC19. All the bacteria showed indole-3-acetic acid (IAA) producing capacity. Among the PGPR used, the highest rooting ratios were obtained at 47.50% for semi-hardwood stem cuttings from Bacillus RC03 and Bacillus simplex RC19 treatments and 42.50% for hardwood stem cuttings from Bacillus RC03. As well, Comamonas acidovorans RC41 inoculations indicated higher value than control treatments. The results suggest that these... |

| At first glance, the compatibility of social theory and resilience thinking is not entirely evident, in part because the ontology of the former is rooted in social interactions among human beings rather than ecological process. Despite this difference, resilience thinking engages with particular aspects of social organization that have generated intense debates within social science, namely the role of humans as integral elements of social-ecological systems and the processes through which given social structures (including material relations) are either maintained or transformed. Among social theoretical approaches, Actor-Network Theory (ANT) is noted for its distinctive approach to these aspects. ANT proposes that human and nonhuman components (both... |

| Boron (B) is an essential micronutrient showing restricted mobility in plants, except in species that synthesize polyols. The ability of kiwifruit to mobilize B through phloem transport has not yet been confirmed, despite its ability to synthesize the polyol myo-inositol. This study examined kiwifruit plants in which boric acid enriched with the stable 10B isotope was applied to the distal leaves of mixed shoots with flowers. At 24, 72 and 144 h, both 10B-treated and un-treated leaves and flowers from treated shoots were sampled and subsequently analyzed via mass spectrometry to determine the resulting 11B/10B ratios. Control leaves and flowers showed a natural ratio, varying between 3.82 and 4.05. In contrast, the ratios in treated leaves were 1.57 at 24... |

| In this study, the rate of microwave drying method kiwifruit (Hayward variety) was studied. Samples in a completely randomized design with three different thicknesses of 4, 6 and 8 mm and weight of 15 g and three power of 200, 300 and 400W, with three replications, were dried in the microwave dryer. The samples were weighed every 30 seconds, and then moisture ratio was obtained. According to the results of experiments with different thicknesses Kiwifruit by increasing power, drying time decreased. The amount of effective moisture diffusion coefficient of kiwifruit slices with thickness of 4, 6 and 8 (mm), 3.25×10-9 to 6.49×10-9 (m2/s) and 3.65×10-9 to 1.83×10-8 (m2/s) and 1.29×10-8 to 3.25×10-8 (m2/s) was changed. The value of the effective activation... |
