Abstract The evaluation of the physical properties of growing media seems essential in crops such as strawberry, which their flowering depends on environmental parameters. Thus, this study aimed to evaluate Fragaria × ananassa development in growing media with different physical properties. For this purpose, it was focused on the correlation of growing media properties with the flowering time and some growth indices in different strawberry cultivars (i.e., ‘Camarosa’, ‘Mrak’, and ‘Selva’). The physical properties of growing media determined included pH, Electrical conductivity (EC), porosity, bulk density, particle density, organic and inorganic materials, water-holding capacity, and air-filled porosity. The flowering and growth responses of studied cultivars to growing media were different. Such that the rice hull growing medium accelerated the flowering time in ‘Camarosa’ and ‘Mrak’. ‘Camarosa’ and ‘Selva’ showed slow growth in rice hull, and ‘Mrak’ grew slowly in media of rice hull and sycamore pruning waste. An increase in the porosity or decrease in the bulk density accelerated the floral emergence and blooming in ‘Camarosa’. An increase in the air-filled porosity accelerated the floral emergence and blooming, and the beginning time of the fruit set in ‘Mrak’. It was also observed a reduction of the leaf number with increasing the porosity in ‘Mrak’. Decreasing each of the EC and bulk density also increasing the porosity reduced leaves number to the flowering step for ‘Camarosa’. Based on these observations, it was considered that the effect of growing media on flowering time and growth indices was genotype-dependent in strawberry such that flowering and growth responses of ‘Selva’ showed less correlation with the physical properties of media.

草莓的开花时间和一些生长指标受生长介质物理性质的影响

摘要 在草莓等作物中，对生长介质的物理特性进行评估似乎是必不可少的，因为草莓的开花取决于环境参数。因此，本研究旨在评估草莓 × ananassa 在具有不同物理特性的生长介质中的发育。为此，它侧重于不同草莓品种（即'Camarosa'、'Mrak' 和'Selva'）的生长介质特性与开花时间和一些生长指数的相关性。确定的生长介质的物理特性包括 pH 值、电导率 (EC)、孔隙率、堆积密度、颗粒密度、有机和无机材料、持水能力和充气孔隙率。研究品种对生长介质的开花和生长反应不同。因此稻壳生长培养基加速了'Camarosa' 和'Mrak' 的开花时间。'Camarosa' 和'Selva' 在稻壳中生长缓慢，'Mrak' 在稻壳和梧桐修剪废料的培养基中生长缓慢。孔隙率的增加或堆积密度的降低加速了'Camarosa'的花出现和开花。充气孔隙率的增加加速了花的出现和开花，以及'Mrak'中果实的开始时间。还观察到随着“Mrak”中孔隙率的增加，叶数减少。降低 EC 和体积密度中的每一个也增加了孔隙率，从而减少了 'Camarosa' 开花阶段的叶子数量。基于这些观察，
