摘要:
<正>以宣木瓜Chaenomeles speciosa Nakai种子的子叶、胚轴为外植体,研究不同生长调节物质对愈伤组织诱导的影响。结果表明:1在子叶诱导实验中,2,4-D比NAA更高效地诱导出愈伤组织,且愈伤组织生长量大,经过继代培养后仍能保持较好的长势。2,4-D与KT组合的效果好于2,4-D与BA的组合。筛选试验表明:MS+2,4-D1.0mg/L+KT0.1mg/L对子叶愈伤组织诱导及其生长效果较好。2胚轴愈伤组织诱导率达到87%,而子叶的诱导率较低,为69%。虽然NAA的诱导效果较好,但愈伤组织生长速度较慢;2,4-D能高效诱导愈伤组织,但容易出现玻璃化。提高NAA,2,4-D和BA的浓度,愈伤组织呈现水浸状的比例和程度都会相应提高。试验中,2,4-D0.1mg/L+BA0.3mg/L处理对胚轴愈伤组织的诱导效果较好。
Abstract:
This paper analyzed the composition of urban forest in Nanjing briefly. The economic analysis was used to estimate the urban forest ecological value. The ecological value consists of manufacturing oxygen and fixing carboblic, purifying environment and sightseeing in forests. Nanjing street trees and forest resources in the scenic areas of Dr. Sun Yat-Sen’s Mausoleum were investigated. The economic value of urban forests was calculated. From the economics, it was a good suggestion to accelerate the development of urban forestry and ecological urban construction.
