Transcriptome Analysis of Jujube (Ziziphus jujuba Mill.) Response to Heat Stress

Table 2

Effect of high temperature stress on stomatal density and stomatal opening rate of seedlings.

	Heat treatment time (d)
	0	1	3	5	7
Stomatal density (number/figure)	15.44c	15.93bc	19.19a	19.75a	18.75b
Stomatal opening rate (%)	38.49c	43.50c	72.31a	59.81b	58.00b

Note: stomatal density is represented by the number of pores in the picture. Stomatal opening rate is the number of stomatal openings in a picture divided by the total number of stomatal openings.
