Abstract: One of the main problems of almond
producers in Iran is the irregular and fluctuating production rates. This is
the result of early flowering of native genotypes and coincidence of their
flowering times with a cold spring.An experiment was done on three major
commercial of Monagha, Sh- 12 and ,
Sh-18 through a double-factor factorial in the form of random blocks(cultivar,
cold and phenological phase at 3, 6 and 3l levels respectively) with three
replications with ages around 15 years. The results
showed that the highest rate of proline was found at -6° C in Sh-18
(3.43μmol/g). While the highest rate of
carbohydrates at -6 °C were found in cultivar Monagha (0.305mg/g). The rate of calcium, magnesium, potassium and
sodium at different stages of bud development of the experimental cultivars
under cold stress was diverse significantly. According to this research results, Sh- 12 of
almond was observed more resistant than other cultivars.
