Pseudoverticillata, but there was no significant change in Celtis wightii. There was no significant change in leaf area specific hydraulic conductivity K(subscript l between the two seasons in all the three species, which may caused by the adjustment in hydraulic architecture through partial loss of leaves during the dry season. In the dry season, maximum carbon assimilate rate A(subscript max was significantly lower than that of the wet season in all the three species.

除油朴的枝条边材比导率K(下标 s在旱季和雨季没有显著性差异外,尖叶闭花木和轮叶戟的K在旱季都有显著的降低;而枝条的叶比导率K(下标 l三树种在两个季节间均无显著变化。K在旱季没有显著性降低,可能是常绿树种在旱季通过脱落部分叶片以调整其水力结构来保持较高的单位叶面积的水分供应。

The results showed that 22.5μL/L of clove leaf oil had the best preservation effect on peach. After 35 days of stock, the sound fruit rate was 94%, 46.9% higher than compared group. The rotten index and the browning index were 94.1% and 85.2% lower than the control, respectivly, and the treatment could remarkablely reduce the respiration rate and ethylene release, and postponed ethylene release peak and respiration peak 5 and 10d, respectively in comparison with CK, it also delayed the drop of firmness and contents of titrable acids of the peach. When stored for 35d, firmness of control group and 22.5μL/L of clove leaf oil were decreased 60% and 34% compared with initial storage, and the activities of SOD, CAT and POD were enhanced, but the contents of SSC had no obvious difference with control.

结果表明,与对照相比,22.5μL/L丁香叶油处理对桃果实的防腐保鲜效果最好,贮藏35d时好果率为94%,比对照提高了46.9%,腐烂指数和褐变指数分别比对照低94.1%和85.2%;丁香叶油处理可以有效降低桃果实的呼吸强度和乙烯释放量,呼吸强度高峰和乙烯释放量高峰分别推迟5和10d,延缓了果实硬度和可滴定酸含量下降的速度;贮藏35d时对照和22.5μL/L丁香叶油处理果实硬度分别比贮藏初期降低了60%和34%;丁香叶油处理提高了超氧化物歧化酶、过氧化氢酶、过氧化物酶3种膜脂过氧化物酶的活性,但可溶性固形物含量与对照相比无明显差异。

Historically,ākyamuni transmitted Dharma to Kāyapa, but he didn't prohibit the establishment of various sects; when Zen was transmitted to China, it gradually divided into a northern sect and a southern sect, which didn't stop people from learning Buddhism; Venerable Master Taixu didn't categorize himself into any sect, and put forward a widely accepted concept---"Living Buddhism", thus Buddhism was spread and transmitted to a broad extent.

回想,释迦世尊虽然拈花一笑传法迦叶,却并没禁止后来琳琅满目的宗派。禅宗传到中国,五祖后又&南顿北渐&,却不妨碍接引南北众生,六祖时衣钵不再传,却一花开五叶,更加精彩纷呈;太虚大师无宗无派,他的弟子们四处参学,显密并弘,至今日,大师&人间佛教&的理念更为社会广泛接受,使佛法真正传承和弘扬开来。

The test results of acute toxicity were examined with Pearson's degree of fitting. The results indicated that the silkworm was extremely sensitive to Chlorantraniliprole. The median lethal concentration (LC50) was 4.0905×10^(-3) mg/L and median lethal dose (LD50) was 1.1435×10^(-8) mg/larva for the 3rd instar newly exuviated larvae. No toxicity was observed when normal concentrations of Chlorantraniliprole were used to fumigate the silkworm rearing room. Both irrigation and leaf spraying with 1.25×10^(-4) mg/L Chlorantraniliprole solution showed strong systemic transmission properties in root, leaf and whole plant. The residual toxic period of this insecticide to silkworm was very long. Mulberry leaves sprayed with 1.25×10^(-4) mg/L Chlorantraniliprole solution could still cause 100% mortality of the 3 and 5 instar larvae after 60 d. Furthermore, toxic reaction was very quick. The poisoning symptoms emerged within 1~5 h after feeding on the poisonous leaves. The poisoned larvae experienced such symptoms as stopping ingestion, remaining still, vomiting slightly and body atrophy sequentially, and died ultimately.

食下毒力试验结果经Pearson拟合度检验表明,氯虫苯甲酰胺对3龄起蚕的食下致死中浓度(LC50)为4.0905×10^(-3)mg/L,致死中量(LD50)为1.1435×10^(-8)mg/头;药剂在常规浓度下对家蚕无熏蒸毒性;1.25×10^(-4)mg/L稀释药液对桑树根灌和喷叶处理,表现极强的根部、叶部和全株性内吸传导特性;药液对家蚕的残毒期很长,1.25×10^(-4)mg/L稀释药液田间喷雾桑叶,间隔60 d后采叶饲喂3龄和5龄蚕的死亡率均为100%,且中毒反应极快,添食毒叶后1~5 h出现中毒症状,经停止食桑、静伏、少量吐液、蚕体萎缩等过程后陆续死亡。

缓倾斜叶理上的运动方向的线状指示物和斑状变晶中的叶理弯曲或叶理交切轴并无直接关系,这是因为FIA的指向受缓倾斜叶理和斑状变晶边缘上产生的、近乎垂直的叶理之间的交切面控制。

Basal leaves rosulate, persistent; petiole to 6 cm; leaf blade oblong or oblong-spatulate, rarely linear-oblong,(0.3-)0.6-1.7(-1.9) cm × 1.5-4 mm, densely tomentose with 4-6-rayed stellate trichomes 1 or more rays of which forked or with a lateral branch on each side, base attenuate or cuneate, margin entire, apex obtuse. Cauline leaves absent or rarely 1, sessile; leaf blade oblong, tomentose as basal leaves, margin entire, apex obtuse.

基生叶莲座状,宿存;叶柄长达6厘米;叶片长圆形或长圆形匙形,很少线状长圆形,(0.3-)0.6-1.7(-1.9)厘米×-4毫米,密被绒毛具4-6伞辐星状毛1或更多伞辐那分叉或具侧枝在每边,茎生叶缺席的或很少1,无柄;叶片长圆形,象基生叶一样被绒毛,边缘全缘,先端钝。
