摘要：

营养枝通过增大光合面积,使更多的营养物质积累并运输到开花枝从而促进月季生长。为研究营养枝数量对月季冠层和生物量的影响,本研究采用完全随机区组设计,对营养枝数量与开花枝生物量积累关系进行量化,测定了切花月季在1~3枝营养枝处理下的株高、干重、开花枝和营养枝的光合有效辐射(PAR)。结果表明,3枝营养枝处理比1枝、2枝营养枝处理的开花枝株高显著(p<0.05)增加87.83%和45.79%。3枝营养枝处理比1枝、2枝营养枝处理的开花枝总干重显著增加134.69%和52.40%。3枝营养枝处理下,平均营养枝PAR利用率最高,为30.46 g·MJ^-1,比2枝营养枝处理高84.16%,比1枝营养枝处理高219.29%。根据鲜切花月季等级评价,3枝营养枝处理下总开花枝为54枝,其中A级有4枝,占A级开花枝总量的57.14%;B级有10枝,占B级开花枝总量的52.63%。3枝营养枝处理下,开花枝的株高、总干重、PAR利用率及切花等级最高,说明营养枝对开花枝生长和生物量积累有积极作用。

Abstract:

Vegetative branches promote rose growth by increasing the photosynthetic area, allowing more nutrients to accumulate and transport to commercial flower branches. To investigate the effects of the number of vegetative branches on the canopy and biomass of roses, a randomized complete block design was adopted to quantify the relationship between the number of vegetative branches and the accumulation of biomass in commercial flower branches. The plant height, dry weight, photosynthetically active radiation (PAR) of commercial flower branches and vegetative branches of cut roses were measured under 1-3 vegetative branches treatments. The results showed that the plant height of commercial flower branches treated with three vegetative branches significantly (p<0.05) increased by 87.83% and 45.79% compared with those treated with one or two vegetative branches. The total dry weight of commercial flower branches treated with three vegetative branches significantly increased by 134.69% and 52.40% compared with those treated with one or two vegetative branches. Under the treatment of three vegetative branches, the average PAR utilization rate of vegetative branches was the highest, at 30.46 g·MJ^-1, which was 84.16% higher than the treatment of two vegetative branches and 219.29% higher than the treatment of one vegetative branch. According to the grading evaluation of fresh cut roses, the total number of commercial flower branches under the treatment of three vegetative branches was 54, of which 4 were A-grade, accounting for 57.14% of the total number of A-grade commercial flower branches. There were 10 B-grade branches, accounting for 52.63% of the total number of B-grade commercial flower branches. Under the treatment of three vegetative branches, the commercial flower branches had the highest plant height, total dry weight, PAR utilization rate, and cut flower grade, indicating that vegetative branches have a positive effect on the growth and biomass accumulation of commercial flower branches.

Key words: cut rose, vegetative branch, biomass accumulation, photosynthetically active radiation
