摘要:

以3个品种茄子幼苗为试验材料,运用二次饱和D-最优设计,探究了设施内暗期补充UV-B辐射对茄子幼苗生长发育的调控作用。通过构建幼苗生长参数及壮苗指标与UV-B辐射剂量(包括强度和处理时长)之间的数学关系模型,系统分析了UV-B辐射的生物学效应。结果表明:UV-B辐射显著影响了茄子幼苗的生长指标,且不同品种对UV-B辐射的敏感性存在差异;模型解析表明,随UV-B辐射强度或时间的增加,茄子幼苗株高、单株地上部干重、单株地下部干重都有不同趋势的变化,壮苗指数则皆先升高后降低;UV-B辐射强度与处理时间存在明显的交互作用,且这种互作效应在不同品种间表现出特异性;经模拟运算,本试验中培育普通茄子壮苗的适宜UV-B辐射强度和辐射时间为16.9~17.8 μW·cm-2和4.2 h·d-1;培育砧木茄子壮苗的适宜UV-B辐射强度和辐射时间为22.0~25.0 μW·cm-2和1.6~3.3 h·d-1。

Abstract:

Using seedlings of three eggplant varieties as experimental materials,a quadratic saturated D-optimal design was employed to investigate the regulatory effects of supplemental UV-B radiation during the dark period on eggplant seedling growth in protected cultivation. Mathematical models between seedling growth indicators and the seedling vigor index and UV-B radiation dose (including intensity and duration) were established,and the biological effects of UV-B radiation were systematically analyzed. The results showed that UV-B radiation significantly affected the growth indicators of eggplant seedlings,and the sensitivity to UV-B radiation varied among varieties. Model analysis revealed that with increasing UV-B radiation intensity or duration,plant height,shoot dry weight per plant,and root dry weight per plant of eggplant seedlings exhibited varying trends,while the seedling vigor index first increased and then decreased in all cases. There was a significant interaction between UV-B radiation intensity and treatment duration,and this interaction effect showed specificity among different varieties. Through simulation,the optimal UV-B radiation intensity and duration for cultivating vigorous seedlings of common eggplant in this experiment were 16.9-17.8 μW·cm-2 and 4.2 h·d-1,respectively;and for rootstock eggplant vigorous seedlings,the optimal values were 22.0-25.0 μW·cm-2 and 1.6-3.3 h·d-1,respectively.
