Transcriptomic changes in Cucurbita pepo fruit after cold storage: differential response between two cultivars contrasting in chilling sensitivity

Table 1 Changes on quality parameters in chilling-tolerant (Natura) and chilling-sensitive (Sinatra) zucchini fruit stored at 4 °C and 20 °C during 14 days

	Natura			Sinatra
	At harvest	20 °C	4 °C	At harvest	20 °C	4 °C
Weight loss (%)	─	9.50 aA	7.13 bB	─	11.13 aA	10.49 aA
CI-Index (0–3)	─	─	0.47 B	─	─	2.18 A
Electrolyte leakage (%)	6.70 bA	6.22 bB	9.42 aB	7.66 bA	8.33 bA	14.28 aA
MDA (nmol gFW⁻¹)	42.30 aA	37.84 aA	49.72 aB	42.75 bA	38.60 bA	65.93 aA
H₂O₂ (μmol gFW⁻¹)	2.29 aA	2.51 aA	2.62 aB	2.08 bB	2.31 bA	3.56 aA

Values are the mean of 3 biological replicates each consisting in 6 fruits. Within each row and cultivar, different lower case letters indicate that means are statistically different (p < 0.05) according to Tukey’s HSD test (Electro leakage, MDA, and H₂O₂) or un-paired t-test (Weight loss and CI). Within each row and temperature, different capital letters indicate that means are statistically different according to un-paired t-test (p = 0.05). CI chilling injury, MDA malondialdehyde)
