叶面喷施ALA对彩色马蹄莲种球及盆花品质的影响
Effects of ALA foliage spray on bulbs and potted flowers quality of colored Zantedeschia
摘要
Abstract
[Objective]Effects of 5-aminolevulinic acid(ALA)on quality of colored Zantedeschia bulbs and potted flowers were explored to provide technical support for improving the quality of colored Zantedeschia bulbs and potted flowers.[Method]After growing T1 bulbs of colored Zantedeschia cultivars ym039 and ym088 for 45 d and the bulds grew 3-4 leaves,ALA solution of different concentrations was sprayed on leaves of them every 30 d,and clear water was sprayed on control(CK).Leaf number,leaf length,leaf width,plant height and chlorophyll content of all the treated plants were measured.Fresh weight,dry weight,diameter,soluble sugar content and starch content of T2 bulbs were measured after harvesting.The T2 bulbs were planted in pots,then flower bud number,flower transverse diameter and flower longi-tudinal diameter were measured.[Result]Leaf number,leaf length,leaf width and plant height of colored Zantedeschia in-creased at various extents after treated by 10.0-30.0 mg/L ALA,and the effects of 25.0 mg/L ALA were the optimal.The highest chlorophyll contents in leaves of ALA-treated ym039 and ym088 were 124.87 and 120.76 mg/gFW respectively,and the largest fresh weight,dry weight and diameter of bulbs were 84.08 and 72.89 g,70.84 and 61.42 g,19.78 and 19.52 cm for ym039 and ym088,which were obviously higher than CK.The contents of soluble sugar and starch also significantly increased,and the effects of 25.0 mg/L ALA were the best for these indicators.In addition,the maximum number of flower buds,flower transverse diameter and flower longitudinal diameter of T2 bulbs were 4.72 and 4.28,8.20 and 7.83 cm,8.03 and 9.52 cm for ym039 and ym088 respectively,which were significantly higher than those of CK(P<0.05).Correlation analysis showed that after spraying ALA,there was positive co-rrelation among leaf chlorophyll content,soluble sugar content of T2 bulb and flower bud number of potted Zantedeschia.There was significant positive correlation between leaf chlorophyll content and flower bud number of ym088,and extremely significant positive correlation(P<0.01)between soluble sugar content of T2 bulb and flower bud number.[Conclusion]Foliage spraying exogenous ALA can greatly im-prove the quality of colored Zantedeschia bulbs and the potted flowers and 25.0 mg/L treatment has the best effects.关键词
