Abstract:

To study the correlations between seedling cultivation effect of different strawberry varieties and meteorological factors, a field experiment was conducted on four strawberry varieties in Cixi of Zhejiang Province by descriptive statistics and LSD multiple comparative analysis. The results showed that ‘Hongjia’ had the shortest seedlings and the highest SPAD value of leaves with the number of seedlings of 114.0 plants/m². ‘Mengjing’ had the lowest SPAD value of leaves with the number of seedlings of 90.3 plants/m², which was prone to brown angular leaf spot at the later stage of growth. ‘Yuexiu’ was close to ‘Mengjing’ in the capacity of seedling propagation, but the former had the highest mortality of mother plant and was more susceptible to anthracnose and brown angular leaf spot. The seedlings of ‘Mengxiang’ formed the latest, with only 65.5 plants/m². In terms of the germination capacity of stolon, the four varieties were in an order of ‘Hongjia’> ‘Yuexiu’> ‘Mengjing’> ‘Mengxiang’, among which the stolon of ‘Mengxiang’ germinated about 20 days later than that of the other three varieties. In conclusion, the quantity of stolon stabilizes after a period of rapid outbreak with the rise of external temperature. The rate of stolon germination decreases and the seedlings enter the stage of flourishing germination with the accumulation of temperature. Although precipitation inhibits the germination of stolon, it can speed up the germination of seedlings, which has a more significant influence on ‘Mengjing’ and ‘Yuexiu’. ‘Yuexiu’ requires a relatively cool and dry environment for the germination of its stolon.
