摘要: 为探究不同光照强度对微型盆栽月季(Rosa chinensis var. minima)扦插苗生长的影响,本研究以‘果汁阳台'(Juicy Terrazza)、‘仙度瑞拉'(Cinderella)、‘阿波罗宝石'(Apollo Jewel)和‘二乔宝石'(Rose Terrazza Pisce)4个品种为材料,设置3种遮光处理(L1:70%高透光率;L2:45.5%中透光率;L3:17.5%低透光率),通过测定扦插苗地下部(生根数、根鲜质量、生根率)与地上部新梢(长度、展开叶数、茎粗、鲜质量)的生长指标,同时结合光照强度与基质温度的动态监测,筛选适宜扦插繁殖的光照条件。结果表明:(1)遮光处理显著影响光照与基质温度的协同变化,L1处理下平均光照强度最高且上午平均基质温度最低(14.05 ℃),下午基质温度显著升高,平均温度最高达到22.61 ℃;(2)L1处理显著促进根系发育,生根数(15.3条/株)、根鲜质量(0.52 g/株)及生根率(89.5%)较L3处理分别提高36.6%、67.7%与23.8%,品种‘仙度瑞拉'的生根数对高透光率(L1处理)依赖性较强;(3)L1处理下地上新梢的生长同步优化,新梢的长度(均值12.4 cm)、展开叶数(均值6.2片)、鲜质量(均值2.8 g)及茎粗(均值2.3 mm)较L3处理提升36.3%~75.0%,其中品种‘仙度瑞拉'的新梢生长对高透光率(L1处理)依赖性较强,而品种‘二乔宝石'对中透光率(L2处理)适应性较好。综上,70%的透光率是微型盆栽月季扦插繁殖的理想光照条件,建议生产中结合品种特性来调整遮光策略。

Abstract: To investigate the effects of different light intensities on the growth of cutting seedling of miniature potted rose(Rosa chinensis var. minima), this study used four cultivars ‘Juicy Terrazza', ‘Cinderella', ‘Apollo Jewel' and ‘Rose Terrazza Pisce' as experimental materials. Three shading treatments were set(L1:70% high light transmittance; L2:45.5% moderate light transmittance; L3:17.5% low light transmittance). Growth parameters of underground(rooting number, root fresh weight, rooting percentage)and aboveground shoot(length, unfolded leaf number, stem diameter, fresh weight)of cutting seedling were measured, meanwhile combined with dynamic monitoring of light intensity and substrate temperature, to select optimal light conditions for cutting propagation. The results showed that(1)Shading treatments significantly affected the synergistic variation between light and substrate temperature. Under L1 treatment the average light intensity was the highest, and the morning substrate temperature was the lowest(14.05 ℃), while the afternoon substrate temperature significantly raised and reached a peak of 22.61 ℃.(2)L1 treatment markedly promoted root development and rooting number(15.3 roots/plant), root fresh weight(0.52 g/plant), and rooting percentage(89.5%)increased by 36.6%, 67.7%, and 23.8%, respectively, compared to L3 treatment; the rooting number of cultivar ‘Cinderella' exhibited stronger dependence on high light transmittance(L1 treatment);(3)Aboveground shoot growth was simultaneously optimized under L1 treatment with shoot length(average 12.4 cm), unfolded leaves number(average 6.2 leaves), fresh weight(average 2.8 g), and stem diameter(average 2.3 mm)improved by 36.3%-75.0% improvement over L3 treatment. The new shoot growth of cultivar ‘Cinderella' exhibited stronger dependence on high light transmittance(L1 treatment), while cultivar ‘Rose Terrazza Pisce' adapted well to moderate light transmittance(L2 treatment). In conclusion, 70% light transmittance is the ideal light condition for cutting propagation of miniature potted rose, and it is suggested that shading strategy by adjusted based on cultivar characteristics in production.
