Effect of some anti-transpiration on the storage traits of two tomato cultivars

الملخص EN

A storage experiment was conducted on the fruits of two (hybrid) cultivars of tomatoes grown inside plastic tunnels obtained from one of the private farms in Khan Bani Saad district during the spring agricultural season 2020-2021.

the study included the use of two factors, namely the cultivar and the waxing of the fruits, to know the effect of these factors on the storage traits of the fruits of these two cultivars of tomatoes.

the second cultivar is the Siemens cultivar, which is a hybrid.

its fruits are of medium size, with high specific weight, high hardness, and bright red color.

as for the fruit waxing agent, two types of wax were chosen, the first is waxes dysper and the second is paraffin waxes.

the fruits were stored in a refrigerator at a f 5°C for a month.

the experiment was conducted as a factorial experiment with a completely randomized design (CRD), with three replications per treatment.

the obtained data were collected and analyzed according to the used design using the LSD test at the probability level of 0.05., the waxing showed a significant effect on TSS, where the highest percentage when using dysper wax and the lowest percentage when using paraffin wax.

also, the waxing treatment showed significant differences between them, where the highest content of vitamin c was obtained using paraffin wax, and the lowest percentage when using dysper wax, which.

the waxing treatment also gave significant differences in the acidity level characteristic of the fruits, where the highest acidity was 0.603% when using paraffin wax.

in the aspect of respiration rate, there were significant differences between the waxing treatments.

the fruits treated with dysper wax excelled in giving the lowest rate of respiration rate for fruits, which reached 2.973 mg co2 / kg / hour.

the highest average of respiration rate for fruits when using paraffin wax.
