Integrate low temperature and ultra-dry to excogitate better method to prolong seed longevity, at the same time, we found out the optimal method of ultra-dry preservation, screen out to the excellent desiccant with low cost and good effect, validate the method of ultra-dry can use to deal with and conservation even more large numbers of tobacco seed, yet explored seed vigor comedown rule of tobacco seed, that avoid seed vigor loss prematurely.

在此基础上，把超干燥与低温保存有机地结合起来研究，找出了延长烟草种子寿命的更好方法，找出最佳的超干燥保存方法，优选出成本低、效果好的干燥剂，验证了超干燥也可用于更大量烟草种子的处理和保存，初步探明了烟草种子的活力丧失规律，有效预防了种质资源的失传，最大限度地延长种子保存寿命达25年以上。

Hairy roots were induced from tobacco leaves with Agrobacterium rhizogenes LBA1334 harboring agropin type PRil855 and binary vector PIG121HM carrying a kanamycin resistant gene nptll and GUS gene and the good hairy root clones were selected. The root with many root hairs and branches grew vigorously toward all the direction on MS medium without plant hormone and on kanamyain containing medium (km:30mg/L). The structure of the hairy root tip is different from that of ordinary root. Witch was not typical root cap maybe the main cause of losing the geotropism of hairy root. Plantlet regenerated from hairy root when cultured on Ms medium without plant hormone. The nicotine content of the hairy root was little higher than that in the natural roots.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
