Abstract:
... Frost damage during flowering is recognized as one of the most serious agro-meteorological disasters affecting apple production in Shaanxi province, a typical apple producing area in China. Quantitative assessments of flowering frost damage to apple yield are critical for the development of strategies on mitigating yield losses, but have been rarely conducted. For the first time, our study used th ...

The application of frost heaving in the soil has the potential to alter the physical properties of soils and subsequently affect the hydraulic characteristics of saline-alkali soils. However, insufficient research regarding their microscopic cha ...

Abstract:
... Sweet cherry (Prunus avium L.) is one of the economically important fruit crops worldwide. However, late spring frosts occurring in some years can significantly impact sweet cherry productivity through organ and tissue destruction caused by frost damage, and very little is known about frost tolerance or susceptibility of new cultivars. Differential thermal analysis (DTA) was, therefore, used to ex ...
