Revue Marocaine des Sciences Agronomiques et Vétérinaires, 1995 The effects of constant stratification temperatures on breaking peach seed dormancy were evaluated using seed populations with various chilling requirements. Germination at 20"C increased steadily with stratification time. Sorne low chilling populations

(51(1):25-32)Chilling requirement for native Prunus campanulata Maxim in Taiwan
, 2010 臺灣原生山櫻花分布於全島500～2000 公尺的闊葉林，其低溫需求量的評估是比較霧峰地區1996年至2001年六年來四個「桃樹關鍵栽培種」(‘Flordared’、‘Premier’、‘TropicSweet’ 及 ‘TropicSnow’ 等）與山櫻花間的花期早晚次序，再利用台灣需冷模式與三個國外需冷模式（即低於12.9℃的小時數、低需冷油桃模式與猶他低溫單位模式等三種）進行低溫感應起始日至休眠完成期與至盛花期兩個時段的需冷量評估 ...

Chilling requirement to overcome bud dormancy in Intermountain West chokecherry ecotypes
, 2010 Chokecherry (Prunus virginiana L.) is a native North American plant that has potential as a regionally important alternative fruit crop. Seedlings from 13 open-pollinated populations were subjected to chilling temperatures (4°C) for 0, 2, 4, 6, 8, 10, 12,

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

CHILLING REQUIREMENTS OF PLUM AND APRICOT CULTIVARS DURING THE DORMANCY PERIOD
Vědecké Práce OvocnářskéThis study evaluates the endodormancy requirements of a selected of apricot and plum cultivars under the environmental conditions of Holovousy. Between 2023 and 2026, 23 apricot genotypes were tested, followed by 26 plum genotypes evaluated. The Chilling

The Effect of Cold and Drought Stresses on Yield, Yield Components and Water Use Efficiency of some Corn Hybrids (Zea mays L.) [PDF]
Ikufīziyuluzhī-i Giyāhān-i Zirā̒ī, 2017 Cold and drought stresses are considered as the most important factors limiting crop production. To evaluate the effect of these tow stresses on yield and yield components of corn hybrids, a field experiment was implemented in split plots based on a ...

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...
