초록
This study was carried out to research the effect of nutrient composition and GA4+7 on growth, flower quality and bulb development in special hydroponics of cut tulip. Flowering of 'Cassini' was markedly accelerated by standard+GA4+7, K200+GA4+7, N250+GA4+7 treatment, last internode was increased by N250 as compared with other treatment. For 'Christmas Marvel', flowering was promoted by K250+GA4+7, last infernode and total length were also increased with K250+GA4+7 as compared to other treatment. For 'Golden Apeldoorn', flowering was accelerated by K200+GA4+7, last internode was increased with N300+GA4+7 treatment and total length was increased in N250+GA4+7 treatment as compared with the standard plants. Bulb weight and number of 'Cassini', 'Christmas Marvel'and 'Golden Apeldoorn' were decreased by GA4+7 as compared to non-treatment, and bulb diameter was not affected by GA4+7.
