Dynamika kwitnienia roślin karczocha (Cynara scolymus L.) w zależności od metody uprawy [Dynamics of flowering of artichoke globe (Cynara scolymus L.) plants in depending on cultivation method]

The study was carried out in the years 2001-2002 in the Felin Research Center in Lublin. The differences in growth dynamics and morphology of flowering shoots were investigated with regards to a method of cultivation of artichoke. In the year 2001 flowering shoots and flowers occurred the earliest in the year 2001 on artichoke plants cultivated from crowns. In the year 2002 plants cultivated from crowns and transplants produced flowering shoots in the same time. Artichoke plants cultivated from transplants produced flowers earlier than those obtained from crowns. Plants grown from seeds sown in the ground did not produce flowering shoots. They remained as leaves through the whole vegetation period. Definitely more anthodiums produced plants those cultivated from crowns in comparison with obtained from transplants and seeds. Anthodiums which developed on shoots of plants cultivated from transplants and cuttings characterized bigger average height and diameter than anthodiums of plants cultivated from crowns. Artichoke plants differed in the number of leaves. More leaves of smaller length produced plants cultivated from transplants than plants obtained from cuttings and crowns
