如何进行种子的采收?
①母株选择
留种母株应在始花期逐株选择特别健壮、能体现品种特性、无病虫害的单株作母株,并进行妥善栽培、精细管理,以求得优良的种子。
②采种
种子收取,最主要的是掌握其成熟度及果实的形状特征。一般应在种子充分成熟后采收,为此,必须掌握各种花卉种子成熟的特征,如一串红种子成熟时呈褐色。对于菩荚果、荚果、角果等易于开裂的花卉种类,在其未完全成熟时,就宜提早采收。
花卉种子不一定一起成熟,很多都是陆续成熟,宜陆续在晴天的早晨进行采收,因为清晨露水未干,空气湿度较大,花卉的果实不会一触即开裂。对一些果实不开裂、种子也不易散落的花卉,可以一次采收。在种子成熟时恰逢气候不宜,或是过于晚熟的种子,可把未成熟的种子植株连根拔起,捆扎后悬挂于通风处,使之成熟,晾干后再脱粒。
在一株上,宜选其早开花的种子,以及着生在主干或主枝上的种子。晚开花及枝梢的花朵,往往结实不好,特别是夏秋开花的花卉,到晚秋往往种子不能成熟或受精不完全,从而得不到优良的种子。
种子采收后必须立即编号,注明采收日期、名称、颜色等。同一花卉不同品种的种子应分别采收,如三色堇有墨紫色、紫色、黄色、紫黄相问、蓝色等不同园艺品种,必须分别标号和采收,以便得到纯种。
