Almond is one of the most important nut crops in Iran. Due to the suitable climatic conditions, Iran is one of the most important growing centers for wild and domesticated species of almond in world. Native genotypes typically are early flowering, due to late spring frost, often; they have been damaged. So frost damage to the flowers and early developing fruits is one of the most limiting facto...

late spring frost usually damages flowers and reduces yield of almond trees. due to natural sexual reproduction, in most of almond orchards of qazvin province, iran, which have been established through seedling propagation, a vast genetic variation has been occurred. this situation has been provided many possibilities to study different traits of native almond genotypes, to select superior geno...

late spring chilling in spring is largely the cause for limiting almond production, so finding ways to reduce the loss is a priority in horticultural research. the government in iran established sahand horticultural research station in 1968 to invest in some late flowering almond cultivars, and this resulted in seven new cultivars in 1994, which can survive the late chillings that might occur i...

abstract the purpose of this study is to examine the economic impacts of developing and introducing almond late flowering cultivars during 1968 to 2019 years in iran, which developed in sahand horticultural research station using the economic surplus model and field and time series data. the estimation of shift parameter identifies that almond late flowering cultivars make almond supply curve m...

In almond, late frost is the main factor determining viability of culture in cold areas, and flowering remains key addressing this issue. Climate change causing an increase frequency extreme weather events. 2021, period Spain after Filomena storm (11–14 January), which temperatures reached ?20 °C some regions, was a clear expression regard. many almond-growing these low affected closed flower b...

Flowering time is an important agronomic trait in almond since it is decisive to avoid the late frosts that affect production in early flowering cultivars. Evaluation of this complex trait is a long process because of the prolonged juvenile period of trees and the influence of environmental conditions affecting gene expression year by year. Consequently, flowering time has to be studied for sev...

In this study flowering time and other important morphologic traits were evaluated during two years in F1 almond progenies of seventy two seedlings from cross between the intermediate flowering Italian cultivar ‘Tuono’ and the extra-late blooming Iranian cultivar ‘Shahrood-12’. A modified-bulk segregant analysis in combination with the application of the 140 RAPD primers, 87 nuclear ...

Flowering time is an important horticultural trait in almond since it is essential to avoid the late frosts that affect production in early flowering cultivars. Evaluation of this complex trait is a long process because of the prolonged juvenile period of trees and the influence of environmental conditions affecting gene expression year by year. In this research flowering time was studied in an...

Frost damage to the flowers and early developing fruits is one of the most limiting factors in the most almond cultivation regions of the world. This study was undertaken to help understand almond response to frost spring at same phenological stage, in order to develop criteria for the selection of cultivars with improved resistance to frost on the basis of field and laboratory experiments. In ...
