查询词典 rate of growth

Additionally, the water fraction from wood extract can inhibit the root growth on Pak-choi. At 1000 μg/mL, after 72 h, the length ratio of root to shoot was 0.69, and the dry weight of Pak-choi root was only the 20.6% of control. But the extracts of Sapindus mukorossi have no influence on the growth of Pak-choi with normal growth 7 days.

此外，木材抽出物之水分离部则具有抑制胚根生长的作用，经浓度1，000 μg/mL处理72 h之小白菜，胚根与胚茎长比值为0.69，且其胚根乾重仅为对照组的20.6%，但无患子抽出物对正常生长7天后之小白菜并无显著抑制生长作用。

The results of studying the effects of several plant growth regulating substances on pollen germination and tube growth in pear (Pyrus serotina Rhed.) by cultivating pollens in liquid media showed that GA3,TRIA,IAA and 2,4D stimulated pollen germination and tube growth when pollen was cultivated in their lower concentration media.

采用花粉液体培养法研究了植物生长调节物质对梨花粉萌发和花粉管生长的影响，结果表明：较低浓度的赤霉素、三十烷醇、吲哚乙酸及2，4-D均能促进花粉萌发和花粉管生长，而超过一定浓度时却起抑制作用，最适宜于花粉萌发和花粉管生长的赤霉素浓度为50～300mg/L，三十烷醇为3～100mg/L，吲哚乙酸为5～25mg/L，2，4-D为5～10mg/L。

To investigate the significance of serum growth hormone,serum insulinlike growth factor1(IGF1) and urinary growth hormonelevels in the diagnosis of short statured children.

The results indicated that the fragments (HF3～HF8) with higher MW (≥3000) but not those (HF1, HF2) with lower MW (＜3000) had effects on CFU-MK growth. Moreover, HF3～HF8 could act synergically with TPO(10ng/ml) in promoting CFU-MK growth, but HF1, HF2couldnot. In addition, there were no differences in the effects ofHF3～HF8 on CFU-MK growth, suggesting that the synergy of heparin with TPO was associated with its MW, but not its sulfate content or activity of anticoagulation.

结果表明分子量较小的HF1和HF2(＜3000)没有促进CFU-MK生长作用，而分子两较大的HF3～HF8具有促进作用，并且前2者没有协同TPO(10ng/ml)的作用，后6者都有协同作用，后6者之间的作用比较没有差异，提示肝素协同TPO的作用与其分子量有关，而与硫酸基团含量和抗凝活性无关。

Chromatic plastic film and light conversion film has been applied in protected cultivation, and plastic films with different light quality may serve as a non-chemical approach regulating growth and thermoperiodic responses of plants. A few studies showed that light quality affected growth and yield of strawberry, but little is known about its effects on photosynthesis and chlorophyll fluorescence in strawberry leaves, and fruit quality. So it is beneficial to scientific regulating growth and fruiting for strawberry protected cultivation to study on those effects and the interactions between CO2 and N supply on photosynthesis.

而低氮影响植株生长、叶片黄化，进而影响光合作用，导致抗性减弱和产量品质下降；③CO_2供应问题：目前我国草莓栽培常在设施环境下进行，在封闭性强的设施中空气流通不畅，常导致设施内部CO_2供应不足而影响光合作用，进而影响产量和品质；④光不足与光质问题：设施栽培中，光通过玻璃和塑料棚膜后使设施内的光强与光质均发生改变，这些变化特别是光质变化对草莓生长与结果的影响程度尚无明确认识。

Methods 180patients with liver injury owed to various pathogeny were randomly divided into3groups,which were control group A treated with hepatocyte growth-promoting factors,control group B treated with hepatocyte growth-promoting factors and Jinshuangqi,and treatment group treated with hepatocyte growth-promoting factors,Jinshuangqi and Tongkang tablet.

The results indicated that the growth of 3-year-old Prunus salicina was significantly higher than that of the other species, such as 139.1% and 153.7% higher than Toona sinensis and Juglans regia in height growth, respectively. The maximum percentage of DBH more than 1.0 cm was 91.9% for P. salicina. Next were 49.5% and 48.8% for Ulmus pumila and Pteroceltis tatarinowii, respectively. The contents of total N, total P and total K ranged from 1.36% to 2.52% in the leaves of testing species. The highest content of total N and total P was found in the leaves of Catalpa bungei, while the highest content of total K was observed in P. saltcina leaves.

Catarium that is naturally decomposed outdoors has an inhibitive effect on cabbage seed germination. While the inhibition effect increases with increase in extract concentration, it, however, decreases with decomposition time. With regards to the length of cabbage root, 0.1 g·mL-l aquatic extract of E. catarium inhibits root growth at every decomposition stage. With the exception of undecomposed E. catarium , other concentration extracts during decomposition enhances root growth. Aquatic extract from E. catarium also enhances cabbage stem growth.
