不同种源/家系樟树绿枝扦插生根能力及扦插苗生长评价
|
摘要
对18个种源52个家系樟树进行绿枝扦插生根能力及扦插苗生长进行测定与分析,结果表明,不同种源/家系樟树生根能力差异显著。江西瑞昌市、湖北黄冈市、江西乐安县和江苏南通市的种源生根率较高,生根率分别为80. 69%、76. 68%、73. 08%和71. 19%,其中江西瑞昌市029、江西瑞昌市030、湖北黄冈市027、江苏南通市001、江苏南通市003和福建厦门市018生根率达到75%以上。不同种源/家系樟树1a生扦插苗株高和地径生长差异显著,四川广元市种源/家系生长最好,株高最大值108. 92 cm、地径1. 05 cm,其次是广东广州市和福建厦门市,平均株高87. 26 cm和82. 12 cm,地径0. 76 cm和0. 71 cm,江西乐安县和江西吉水县种源/家系生长最差,株高50cm、地径0. 45 cm左右。不同种源/家系樟树1 a生扦插苗生物产量差异显著,四川广元市种源/家系生物产量最高,地上部分鲜重和干重最大值分别为443. 32 g和193. 51 g,其次是广东广州市、福建厦门市和江苏盐城市,平均鲜重达到210 g,干重90 g,江西乐安县和江西吉水县种源/家系生物产量最低。综合扦插苗生长指标,四川广元市种源/家系生长最好,其次是广东广州市和福建厦门市,江西本地种源生长表现较差,本地种源不存在优势。
In the paper,the rooting ability and growth trait of Cinnamomum camphora of 18 provenances and 52 families were measured and analyzed. The results show that the rooting ability of Cinnamomum camphora from different provenances/families was significantly different. The provenances of optimal rooting rates were Ruichang in Jiangxi,Huanggang in Hubei,and Nantong in Jiangsu etc. The rooting rates were 80. 69%,76. 68%,73. 08% and 71. 19%,respectively. The rooting rates were over 75% from Jiangxi-Ruichang029,Jiangxi-Ruichang030,Hubei-Huanggang027,Jiangsu-Nantong001,Jiangsu-Nantong003 and Fujian-Xiamen018 families. There were significant differences in height and diameter of annual cutting seedlings of Cinnamomum camphora among different provenances/families. The provenance/family growth was the best in Sichuan-Guangyuan,with the maximum height 108. 92 cm and diameter 1. 05 cm,followed by Guangdong-Guangzhou( average height and diameter,87. 26 cm and 0. 76 cm) and Fujian-Xiamen( average height and diameter,82. 12 cm and 0. 71 cm),and the Jiangxi-Le'an and Jiangxi-Jishui were the worst,the height and diameter were about 50 cm and 0. 45 cm. The biological yield was significantly different among different provenances/families of annual cutting seedlings of Cinnamomumcamphora. The yield was the highest in Sichuan-Guangyuan. The maximum aboveground fresh and dry weight was 443. 32 g and 193. 51 g. Followed by Guangdong-Guangzhou,Fujian-Xiamen and Jiangsu-Yancheng,the average fresh and dry weight was above 210 g and 90 g. And that in Jiangxi-Le'an and Jiangxi-Jishui was the lowest. Synthesizing the growth trait,the provenances of the best growth was Sichuan-Guangyuan,followed by Guangdong-Guangzhou and Fujian-Xiamen. The native provenances from Jiangxi have no advantage,and the growth performance was poor.
