Examining whether a phenophase occurrence date in the current year affects the same phenophase occurrence date in the following year is crucial for developing cross-year phenological prediction models. Here, we carried out correlation analyses between leaf unfolding start (LUS)/leaf fall end (LFE) dates in the current and following years for four ...

Phenophase Prediction Model for Safflower
Journal of Agriculture Research and Technology, 2022Field experiments were conducted during 2017-18 and 2018-19 on clay loam soils at research farm of Dry Farming Research Station, Solapur, to study the influence of sowing time on phenology and growth of the safflower cultivars and to develop the phenophases prediction model based on the agro meteorological indices.

Spectral detection of subarctic vegetation phenophases
1995 International Geoscience and Remote Sensing Symposium, IGARSS '95. Quantitative Remote Sensing for Science and Applications, 2002Boreal and subarctic plant phenophases are good indicators of global climatic change. Ground information is needed for satellite remote sensing to assess plant phenophases. A boom-mounted four-band spectroradiometer was installed to observe shrub canopies during the 1994 growing season in northernmost Finland.

Nighttime transpiration of Populus euphratica during different phenophases
Journal of Forestry Research, 2018Evidence exists of nighttime transpiration and its potential impact on plant/water relations for species in a diversity of ecosystems. However, relevant data related to typical desert riparian forest species remains limited. Accordingly, we measured sap flow velocity of Populus euphratica using the heat ratio method between 2012 and 2014.

Detecting Phenophases of Subarctic Shrub Canopies by Using Automated Reflectance Measurements
Remote Sensing of Environment, 1999Boreal and subarctic plant phenophases are advantageous indicators of climatic change on a global scale. Remote sensing is a promising technique for assessing such changes over extended areas. An automated field measuring system collected seasonal reflectances of natural shrubs in visible, near-, and mid-infrared wavelength ranges.

The leaf phenophase of deciduous species altered by land pavements
International Journal of Biometeorology, 2018It has been widely reported that the urban environment alters leaf and flowering phenophases; however, it remains unclear if land pavement is correlated with these alterations. In this paper, two popular deciduous urban trees in northern China, ash (Fraxinus chinensis) and maple (Acer truncatum), were planted in pervious and impervious pavements at ...

Opposite effects of winter day and night temperature changes on early phenophases
Ecology, 2019AbstractChanges in day (maximum temperature, TMAX) and night temperature (minimum temperature, TMIN) in the preseason (e.g., winter and spring) may have opposite effects on early phenophases (e.g., leafing and flowering) due to changing requirements of chilling accumulations (CAC) and heating accumulations (HAC), which could cause advance, delay or no ...

Phenophases alter the soil respiration–temperature relationship in an oak-dominated forest
International Journal of Biometeorology, 2006Soil respiration (SR) represents a major component of forest ecosystem respiration and is influenced seasonally by environmental factors such as temperature, soil moisture, root respiration, and litter fall. Changes in these environmental factors correspond with shifts in plant phenology.

Contrasting responses of early‐ and late‐season plant phenophases to altered precipitation
Oikos, 2023Precipitation is a key driver of plant phenology in addition to temperature and photoperiod. Although a few studies have explored phenological responses to altered precipitation, the general patterns of sequential phenophase responses and their potential drivers remain elusive.
