Effect of Diniconazole Treatments on Growth of Plug Seedlings in Melon (Cucumis melo L.)

다국어 초록 (Multilingual Abstract)

Abstract - In order to promote healthy seedlings, foliar spraying of triazole-based diniconazole is mainly used in nurseries.
As the inhibitory effect of foliar spraying weakens, plant growth inhibitors are sprayed several times for prevention of over-growth and healthy seedling in some varieties, so the foliar spraying method causes fatal damage to the growing point of the plants. To solve the problem of the foliar spraying treatment, the effects between the foliar spraying and the irrigation with drenching methods on the growth inhibition of plug seedlings were evaluated using diniconazole treatments in melon (Cucumis melo L. var. ‘Ochigi’). As a result of the experiments, plant height, hypocotyl length, leaf length and width of all the melon seedlings were decreased significantly as the treatment concentration of diniconazole increased. In particular, compared to the foliar spraying, the inhibiting effect of the irrigation treatment on seedling growth was maintained until the shipment time of plug seedlings. Thus, the irrigation treatment was more effective than the foliar spraying to yield healthy seedlings. The result be able to be used as fundamental data for yielding healthy seedlings of gourd crops.
