Fig. 1From: Full-length transcriptome profiling reveals insight into the cold response of two kiwifruit genotypes (A. arguta) with contrasting freezing tolerancesMicroscopy observations of kiwifruit shoot anatomical structure. (a) Images of the anatomical structure of shoots after 0 h, 1 h, and 4 h of treatment (− 25 °C) for both genotypes. (b) Anatomical structure images of untreated shoots of both genotypes. I, the ratio of pith; II, the vessel density; III, the ratio of xylem; IV, the ratio of phloem. (c) Parameters of the anatomical structure of both genotypes. The bars represent the standard errors of the means (n = 3). The asterisks indicate that the values are significantly different (** for P < 0.01)Back to article page
