例句與造句

1. This review includes the following subjects : induction frequency of haploids depend on genotypes , developmental stage of explants , temperature pretreatment of the explants , medium composition and the conditions of cultivation
   迄今己有9個(gè)科21種植物用這一方法誘導(dǎo)出單倍體植株，植物的基因型、外植體的發(fā)育程度、接種前的預(yù)處理、培養(yǎng)基和培養(yǎng)條件等均能影響誘導(dǎo)率的高低。
2. The results showed that high concentration of 2 , 4 - d was required for callus induction from mature seeds of tall fescue , and combination of 8mg / l 2 , 4 - d with 2mg / l aba gave best induction effects . by slicing sterilized seeds longitudinally or cutting embryos , callus induction frequency was profoundly increased over intact seeds from one and half to eight times . adoption of ms basal medium and supplementation of 0 . 5g / l casamino acids and 0 . 5g / l glutamine in medium were found to help to facilitate callus induction
   研究表明，高羊茅成熟種子愈傷組織誘導(dǎo)需要較高濃度的2 ， 4 - d ，以8mg l2 ， 4 - d與2mg laba配合能獲得最佳的誘導(dǎo)效果；種子滅菌后縱切或切胚，可使出愈率成倍提高；采用ms基本培養(yǎng)基和在培養(yǎng)基中添加0 . 5g l的水解酪蛋白與谷氨酰胺也有助于提高出愈率；低劑量( 10gy )射線輻照處理對(duì)成熟種子愈傷組織尤其是胚性愈傷組織形成有一定的刺激效應(yīng)。
3. Pre - differentiation and proper partial desiccation of calli before transferred to regeneration medium was found to apparently improve the frequency and quality of plant differentiation . with our optimized culture condition and treatment style , induction frequency of pei ' ai64s and 9311 can be reached 62 . 45 % and 85 . 30 % respectively and after 3 months of subculture calli can remain high - quality embryogenic state , when high - quality embryogenic calli after two times of subculture were used as acceptor , callus differentiation frequency can arrive at 85 . 5 % and 87 . 7 % respectively
   采用我們優(yōu)化后的培養(yǎng)條件與處理方式，培矮64s和9311愈傷組織的誘導(dǎo)頻率分別可達(dá)到62 . 45和85 . 30 ；繼代培養(yǎng)時(shí)間達(dá)三個(gè)月左右仍能保持較好的胚性生長(zhǎng)狀態(tài)；對(duì)于繼代兩次胚性生長(zhǎng)狀態(tài)良好的愈傷組織分化頻率分別可達(dá)到85 . 5和87 . 7 。
4. It's difficult to find induction frequency in a sentence. 用induction frequency造句挺難的
