以硬粒小麦(Triticum durum)品种8131-1为材料,种子于22℃下催芽,然后置于网式发芽床上保温5天,再在4～8℃室温下培养5天。选择整齐一致的苗(具2.0片真叶)移栽,每盆移栽7株(盆口面积4.15dm~2,装肥土12.46dm~3)。分别进行BR(100ppb)和PP333(14,280,420,560ppm)处理,以清水为对照,每处理灌10ml处理液,试验重复2次。一周后每盆浇Hoagland培养液100ml,另外加施10ml5％
Using Triticum durum variety 8131-1 as material, the seeds were germinated at 22 ° C, then placed on a net germination bed for 5 days and incubated at 4~8 ° C for 5 days at room temperature. Select neat and consistent seedlings (with 2.0 true leaves) transplanting, transplanting 7 pots per pot (basin area 4.15dm ~ 2, loading soil 12.46dm ~ 3). BR (100ppb) and PP333 (14,280,420,560ppm) were treated with water as a control, each treatment irrigation 10ml treatment solution, the test was repeated 2 times. One week later, each pot was poured Hoagland culture medium 100ml, plus 10ml5%
