L’orchidea coda di volpe (Rhynchostylis retusa L.) è una pianta da fiore ornamentale attraente e pregiata, diffusa nel Sud-est asiatico. È apprezzata per la sua bellezza e per le sue proprietà medicinali. Lo scopo di questo studio era valutare gli effetti di vari substrati di coltivazione e di un ormone vegetale (acido indolo-3-acetico, IAA) sulla crescita dell’orchidea coda di volpe. È stato condotto un esperimento in vaso in una serra a rete presso l’Università Agraria di Sylhet dall’8 marzo 2025 al 22 ottobre 2025. Sono stati utilizzati tre substrati di coltivazione (guscio di cocco, corteccia d’albero e segatura) e quattro diverse concentrazioni di IAA (0, 2, 4 e 6 ppm). I trattamenti sono stati disposti secondo un disegno completamente randomizzato (CRD) con tre repliche. L’IAA è stato applicato tramite irrorazione su foglie, radici e substrati di coltivazione a intervalli di 15 giorni. I dati sono stati registrati a intervalli di 15 giorni fino a 225 giorni dopo l’attecchimento delle piante. I risultati hanno mostrato che sia i substrati che la concentrazione di IAA hanno influenzato in modo significativo la crescita dell’orchidea Foxtail. Tra i substrati, le piante coltivate su segatura presentavano il numero più elevato di foglie (8,08) e la lunghezza fogliare maggiore (9,72 cm) rispetto a quelle coltivate su buccia di cocco e corteccia d’albero.
