大菱鲆

Vitrification was firstly introduced into cryopreservation of marine fish embryos in the present study. We used the sea perch , flounder and turbot embryos as materials and investigated marine fish embryos vitrification technique systemically.

本课题首次将玻璃化冷冻思想引入海水鱼类胚胎冷冻保存研究，首次利用珍贵海水养殖鱼类花鲈、牙鲆和大菱鲆不同发育阶段的胚胎做为实验材料，对海水鱼类胚胎玻璃化冷冻保存技术进行了较系统的研究。

VSD2 suitable for the eryopreservation of sea perch embryos and PM1、PM2、PM3 and PM4 suitable for flounder embryos and PMP1 suitable for turbot embryos were chosen by adjusting the ratio of cryoprotectants in BS2 and equilibrating embryos in vitrification solutions.

在基础液BS2中对抗冻剂配比进行调整，经过胚胎平衡实验，筛选出了适合于牙鲆胚胎的玻璃化液PM1、PM2、PM3和PM4，适合于大菱鲆胚胎的玻璃化液PMP1。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

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.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
