【摘要】 本试验于2006-2009年进行,依托国家果树种质福州枇杷圃收集保存的丰富种质资源,以资源圃全园繁殖更新为契机,在统一砧木、统一地点、统一定植、统一管理条件下,系统地开展枇杷种质资源营养期鉴定。研究结果表明:246份枇杷种质资源的营养期6个月至42个月,苗木定植后的42个月内处于迅速生长期,随树龄的增长树体生长量成倍增加;中心枝抽穗率、侧枝抽穗率、枝梢抽穗率随树龄的增长逐年提高;中心枝数、侧枝数、枝梢总数与中心枝抽穗数、侧枝抽穗数间呈极显著正相关,随树龄的增长相关越密切。经多年鉴定结果认为,营养期的评价标准为:特短(苗期或定植当年抽穗,植株抽穗率达80%、枝梢抽穗率达50%);短(苗期或定植当年抽穗);中等(定植后18个月抽穗);长(定植后30个月抽穗);特长(定植后42个月抽穗),并筛选出营养期特短的种质资源6份。更多还原

【Abstract】 The experiment was conducted in 2006-2009,rely on the rich germplasm collected and conserved in National Field Genebank for Loquat in Fuzhou.Taking the regeneration of resources in the whole field as an opportunity to carry out the identification of loquat vegetative period,under the uniform stock,uniform location,uniform planting,and uniform management conditions.The result showed that,from seedling to 42 months after planting,number of shoot heading and rate of shoot heading of 246 loquat germplasm resources were identified for 4 years.The results showed that nutrition of loquat germplasm resources was between 6 months to 42 months.In 42 months after planting,the loquat germplasm resources were at a rapid growth stage,with the plant increment was highly correlated to the plant growing.Rate of center shoot heading,rate of lateral shoot heading and rate of shoot heading were increased with the plant growing.Central shoots number,lateral shoots number and shoots number were highly correlated to center shoot heading number and lateral shoot heading number,and the relationship was strengthening with the plants growing. Based on years of survey results,nutrition evaluation criteria was proprosed:very short (flowering in seeding or planting 12 months,rate of plants heading more than 80%,rate of shoot heading more than 50%),short(flowering in seeding or planting 12 months),medium(flowering in planting 18 months),long(flowering in planting 30 months),very long(flowering in planting 42 months),and 6 special germplasm with very short nutrition were selected.更多还原
