Lesser appleworm, Grapholita prunivora (Walsh), eggs were subjected to cold storage conditions at 2.0 degrees C +/- 0.2 degrees C for 0-90 d. The most tolerant embryonic stage was the blackhead stage (96-120-h-old eggs) with an LT90 of 25 d. The four instars of lesser appleworm were subjected to cold storage conditions at 2.0 degrees C +/- 0.2 degrees C for 0-280 d. The fourth instar was the mo...

nowadays, a lot of frost damage is inflicted upon vineyards because of changing weather conditions as well as introducing new of cultivars and genotypes from different geographical regions. on the other hand, the prevalence of a wide variety of grapes in iran, the provides possibility of selection of superior and cold tolerant varieties (or single plants) which is proposed a strong hypothetical...

Low temperature is a key factor that limits growth and productivity of many important agronomical crops worldwide. Rice (Oryza sativa L.) is negatively affected already at temperatures below +10°C and is therefore denoted as chilling sensitive. However, chilling tolerant rice cultivars exist and can be commercially cultivated at altitudes up to 3,050 meters with temperatures reaching as low as ...

abstract the grasses cold tolerance is the most important limiting factor for its cultivation in temperate regions, so using cold tolerant cultivars is essential for grasses successful cultivation. in order to evaluation freezing stress tolerance of several species of grasses, this study was conducted in agricultural faculty of ferdowsi university of mashhad as a factorial complete randomized b...

Plant growth and development can be adversely affected by cold stress, limiting productivity. The glutathione S-transferase (GST) family comprises important detoxifying enzymes, which play major roles in biotic and abiotic stress responses by reducing the oxidative damage caused by reactive oxygen species. Pumpkins (Cucurbitamaxima) are widely grown, economically important, and nutritious; howe...

In the Sahel zone of West Africa that extends from Senegal to Chad, temperatures can vary from less than 15 ̋C to 25 ̋C from November to February. These low temperatures affect the growth, development and yield of rice plants, and therefore constitute a major constraint to rice production in the Sahel. In order to identify rice varieties tolerant to cold stress at different developmental stages...

Cold is an environmental factor limiting the growth and yield of agricultural crops. To find cold-tolerant pistachio rootstocks, a factorial experiment was conducted at Pistachio Research Center (PRC), Rafsanjan, Iran during 2017-2018. The factors included six rootstocks (Badami Zarand, Ghazvini, Sarakhs, Integerrima × Badami Zarand, Integerrima × Ghazvini and Integerrima × Sarakhs) and four th...

Temperature is one of the leading factors that drive adaptation of organisms and ecosystems. Remarkably, many closely related species share the same habitat because of their different temporal or micro-spatial thermal adaptation. In this study, we seek to find the underlying molecular mechanisms of the cold-tolerant phenotype of closely related yeast species adapted to grow at different tempera...
