Freezing Resistance of Potato Seedling

Evaluation of Freezing Damage in some Pistachio Seedling Rootstocks

A greenhouse experiment was conducted to evaluate the freezing damage in some pistachio rootstocks by ion leakage and pH changes of leaked solution. A factorial experiment was carried out in randomized block designs (RBD) with three factors: Temperature (A) including 4 ̊C, 0 ̊C, -2 ̊C, -4 ̊C, -6 ̊C, Time (B) including 3, 12, 24h , and Rootstock (C) including P. vera cv 'Badami Zarand' (V13) and 'Sar...

Freezing Injury in Potato Leaves 1 Received

Time-temperature profiles of freezing leaves from frost-resistant (Solanum acaule Bitt.) and frost-susceptible (Solanum tuberosum L. subsp. tuberosum Hawkes) types of potatoes did not reveal any major differences. The pattern of change in resistance of leaves to low voltage, low frequency current during freezing was different in the frost-resistant and susceptible leaves. In tissue sections fro...

A comparison of freezing-damage during isochoric and isobaric freezing of the potato

BACKGROUND Freezing is commonly used for food preservation. It is usually done under constant atmospheric pressure (isobaric). While extending the life of the produce, isobaric freezing has detrimental effects. It causes loss of food weight and changes in food quality. Using thermodynamic analysis, we have developed a theoretical model of the process of freezing in a constant volume system (iso...

Use of local material in seed-bed mixes for production of seedling from true potato seed

Evaluating yield and some traits of potato in prevent freezing cropaid of Jiroft area

In order to finding cultivars with high yield and compatible with potato in the form of fall cultivation in jiroft area, an experiment in randomized complete block design with three replication, was done in Jiroft agricultural research center in 2013. In this experiment height plant, No. Stem, Tuber diameter, Tuber weight/plant, No. tuber and yield were examined. Effect Prevent Freezing Cropaid...
