查询词典 calli

The results showed that 7-day-precultured embryogenic calli had the best responses for bombardment among 2-7 day' preculture duration. Enhanced transformation efficiency was found in the explants treated with high osmotic medium 4h prior to till 24 h after bombardment. Particles of gold and tungsten were both found suitable for rice transformation and there was no adverse effect when tungsten particles were reduced to 1/3 standard amount for DNA precipitation on transient GUS gene expression. However, it was found that gold particle had higher GUS expression at 120 h post-bombardment. A preliminary microprojectile transformation system with an average of 15-20 blue spots/explant GUS expression was routinely obtained for 'Tainung 67' by using the particle gun with 1,100 psi rupture disk, 6 or 9 cm microcarrier flight distance and 4 mm of macrocarrier flight distance setting.

初步结果显示，以预培养2~7日之胚性癒合组织逐日测试转殖率，以预培养7日之培植体表现最佳；培植体於转殖前4小时至转殖后24小时以高渗透压培养基处理，有助於转殖效率之提高；比较金、钨粒子对转殖率在转殖后48h並无不同，但转殖后120 h取样，则金粒子组有较高之蓝点数；钨粒子用量可减少至1/3標准用量对转殖率並无影响；利用基因鎗在使用1， 100 psi裂碟片、大载片至挡片之距离为4 mm、微载髁至射击目標之飞行距离6或9 cm之设定，GUS基因表现之平均蓝点数均可达15~20个／培植体。

Histologically,the activity of cell division in scutellar epithelium and callus cluster derived from it was higher in cultivar Aikoku than Moritawase.Moreover different types of differentiation in the epithelial callus were observed,the rootlike structures and globular cell clusters with epidermislike structure were found in the calli of cultivar Moritawase and Aikoku respectively.

Among different organ explants from ginger lily, only sheaths and leaves cultured in VW medium containing 5mg/l 2, 4-D、0.5mg/l BA、3% sucrose and 200ml/l coconut water for 3 months could be induced to form embryogenic callus. It could produce lots of germinated or ungerminated somatic embryos per culture directly from the surface of calli after culture in MS medium containing 4mg/l BA and 0.05mg/l NAA. The shoots could develop into intact plants with vigorous appearance after 2 months in culture.
