Compared to hairy root system hra3 which came from diploid indigoblue woad ( 2n = 14 ) , hairy roots from autotetraploid indigoblue woad ( 2n = 28 ) grew faster 对四倍体毛状根和二倍体毛状根作了比较，四倍体菘蓝毛状根生长速度大于二倍体。
The growth of this species seems to be very fast : kept in optimal conditions , 6 months will be enough for a scorpling ( cf . photo ) to become adult 这个品种的生长速度看上去非常看；在最适宜的环境下，幼体只用6个月就可以成长为成体。
This , in turn , has a significant impact on the transfer of nutrient from the sow to the piglets , thus affecting growth rate and health status of the litter 随后，对营养从母体到仔猪的转运有明显的影响，因此影响窝产仔猪的生长速度和健康状况。
Enhanced physique : raising aquatic animals immunity to strengthen anti - stress , and increase the survival rate and growth rate , feed efficiency improved 增强体质：提高水生动物的免疫能力，增强抗应激能力，提高成活率和生长速度，提高饵料利用率。
The point seed growth techniques of high quality dkdp crystal in all directions have these features of fast growth rate , high utilization ratio and low growth cost 点状籽晶全方位生长dkdp晶体的方法具有生长速度快、晶体利用率高、生长成本低的特点。
A number of kanamycin resistant transformants were obtained two months later . they were morphologically normal , but grew slower comparing with the control tobacco 2个月后获得了一批卡那霉素抗性烟草植株，抗性植株大田生长表型正常，生长速度相对缓慢。
The tumor growth rate and the transfer of the proliferation of channels depending on the tumor histological type , degree of differentiation , and other biological characteristics 癌肿的生长速度和转移扩散途径取决于癌肿的组织学类型、分化程度等生物学特性。
The growth speed of clone is different in various inoculating density . the experiment result indicates : lower is inoculating density , faster the speed of growth is 在不同接种密度下，克隆的生长速度不同，实验结果表明：分瓶数量越多，克隆总重量增长越多。
Both the growth rate of their vegetative and reproductive modules and their reproductive allocation are different at the different phase of their life cycle 结果表明： 4种植物的营养与繁殖构件在不同物候阶段的生长速度不同，且在整个生长期中生物量分配是动态变化的。
Early weaned pigs require about 300 g . / day of dry feed during the first week postweaning to maintain their pre - weaning growth rate . actual feed intakes , however , rarely exceed 200 g . / day 要想保持断奶前的生长速度，早期断奶的仔猪在断奶后第一周大约需要每天采食饲料300克。
