麻栎成熟合子胚外植体体胚发生和植株再生

为探索麻栎快速繁殖技术新途径,以成熟合子胚为外植体诱导体胚发生,进一步培养形成幼苗。结果表明:体胚诱导以MS+1.0mg.L-1 6-BA+1.0mg.L-1 IBA+1.0g.L-1谷氨酰胺+0.5g.L-1脯氨酸为最优,培养30d诱导率达70.0%;体胚成熟以1/2MS+2.0mg.L-1 6-BA+0.5mg.L-1 IBA+2.0mg.L-1 ABA+4.0g.L-1谷氨酰胺+2.0g.L-1脯氨酸为佳,培养60d,体胚完全成熟;体胚萌发最适培养基为1/2MS+0.2mg.L-1 6-BA+10g.L-1山梨醇,且冷处理有利于体胚的萌发,萌发率高达100%,萌发培养80d,形成再生植株。

山坡地植物燃料品种的能量和养分分析

研究了香港和广东大多数植物燃料品种的热值和养分浓度 ,以及评价它们的燃料品质 .木本热值为 1 7.1 3～ 2 3.51kJ·g- 1 ,而草本热值为 1 5.1 3～ 2 1 .47kJ·g- 1 .在广东和香港 ,常用作燃料的品种热值超过 2 0kJ·g- 1 .N浓度越低 ,越适宜用作燃料 ,因为坡地生态系统损失的N和排放到大气的NOx 少 .木本N浓度为 4.67～ 1 0 .90mg·g- 1 ,而草本N浓度为 3.55～ 1 4.59mg·g- 1 .高P和高K的品种也不宜用作燃料 ,因为山坡地的养分损失大 .P浓度为 0 .1 7～ 1 .0 5mg·g- 1 ,而K浓度为 3.98～ 2 3.0 0mg·g- 1 .木本与草本品种之间 ,热值及养分浓度差异都不显著 .
