A predictive model of frost formation on leaf surface and estimation of frost amount

open access: yesCase Studies in Thermal Engineering, 2023
The massive frost that occurs each year in autumn and spring across subtropical and temperate regions cause severe damage to horticultural crops, therefore, the research for frost formation and estimation of frost amount are important for monitoring and ...

Quantifying frost-weathering-induced damage in alpine rocks [PDF]

open access: yesThe Cryosphere
Frost weathering is a key mechanism of rock failure in periglacial environments and landscape evolution. In high-alpine rock walls, freezing regimes are a combination of diurnal and sustained seasonal freeze–thaw regimes, and both influence frost ...

Frost Heaving and Induced Pressure of Unsaturated Interfacial Zone between Gravel Ballast and Subgrade

open access: yesApplied Sciences, 2022
Most existing railroads are composed of gravel ballast. One of the major issues with gravel ballast is frost damage in cold regions. Gravelly soils are known to be not prone to frost action due to their low water retention capacity and high hydraulic ...

Foliar application of putrescine, salicylic acid, and ascorbic acid mitigates frost stress damage in Vitis vinifera cv. ‘Giziluzum’

open access: yesBMC Plant Biology, 2023
Background Cold stress is an effective factor in reducing production and injuring fruit trees. Various materials, such as salicylic acid, ascorbic acid, and putrescine, are used to alleviate the damage of abiotic stress.

Frost Damage in Poplar on the Prairies [PDF]

open access: yesThe Forestry Chronicle, 1976
Frost cankers in poplar are freeze-killed areas of bark and wood around which woody calluses develop and form burls and frost ribs. Frost dieback is a freeze-killed segment of the stem at the base, tip, or mid-portion of a branch or leader. It may or may not enhance natural pruning of poplar branches depending on whether the basal parts are damaged or

A whole-chain technical system for multi-factor coupling mechanism, risk grading and control of frost damage in cold-region tunnels

open access: yesCase Studies in Thermal Engineering
Amid the predicament of repeated frost damage in cold-region tunnels, the multi-factor coupling mechanism of such damage and precise evaluation based on segmentation and grading have received inadequate attention.

An Automated Plot Heater for Field Frost Research in Cereals

open access: yesAgronomy, 2019
Frost research to improve genetics or management solutions requires a robust experimental design that minimizes the effects of all other variables that can cause plant damage except for the treatment (frost).

Frost Damage Assessment in Wheat Using Spectral Mixture Analysis

open access: yesRemote Sensing, 2019
Frost damage to broadacre crops can cause up to an 85% loss in productivity. Although growers have few options for crop protection from frost, a rapid method for assessing frost-induced sterility would allow for timely management decisions (e.g., cutting
