accumulated temperature of daytime
1.4. the development threshold temperature and available accumulated temperature of the beetle are different with change of relative humidity, at 45%, 55%, 65%, 75% and 85% RH. The development threshold temperature is 20. 1℃, 18.4℃, 18℃, 17.7℃, 17.8℃, respectiveily, average availabe accumulated temperature of a generation is 798.8, 768.1, 674.8, 661.0, 642.5 day degree respectively.
2.of linear regression between days from all ten days of January to buds bursting and accumulated temperature of >0℃, >3℃,>5℃ at the same timee in Evodia rutaecarpa and E. rutaecarpa Var . officinalis.
4.The developmental threshold temperature(DTT) and effective accumulated temperature(EAT) of the larvae and whole larval stage and whole generation of Acyrthosiphon pisum were determined under 80% relative humidity and 6 temperature treatments(12 ℃,15 ℃,18 ℃,21 ℃,24 ℃ and 27 ℃).
6.THE ACCUMULATED TEMPERATURE STEADILY ABOVE 10 ℃ IN THE CENTRAL AND EASTERN TEMPERATE AREA OF THE UNITED STATES OF AMERICA
7.The first reason of dryness index variation is the rainfall change, the second is the chang of accumulated temperature.
8.The Influences of Climate Warming on Active-accumulated-temperature (AAT) and Agricultural-planting-system (APS) in Weiganhe Delta
9.There were some relationships between the development of Bombyx mandarina Moore and effective accumulated temperature, which meant that only if the effective accumulated temperature reached a fixed value could it accomplish a certain stage.
10.In this paper,the negative accumulated temperature(daily minimum temperature<0℃)≤—90℃ and the extreme minimum temperature≤8℃ are used as the orange heavy freeze injuryindex.
