7种芸香科种子的发芽试验

Experiments on Seed Germination of Seven Taxa of the Rutaceae

试验表明芸香科种子不耐贮藏；除枳壳种子在30℃下萌发最佳外，金桔、红桔、芦柑、甜橙、九里香及花椒均以20～30℃变温为最适萌发温度；花椒种子存在休眠现象，冷湿处理及外源GA可解除休眠促进萌发；在金桔及红桔种子中发现有白化苗。

The experiments showed that these rutaceous seeds could not store well; that the seed of poncirustrifoliata Raf. germinated best at 30℃, where as for germination of the seeds of Fortunella margarita Swingle, 2 cultivars of Citrus reticulata Blanco, C. sinensis Osbeck, Murraya paniculata Jacks. and Zanthoxylum bungeanum Maxim. the fluctuating temperature of 20-30℃ was the optimum; that dormancy existed in Zanthoxylum bungeanum seed and could be broken by cold-wet treatment and by addition of exogenous GA, re...
