Purpose: An experiment was conducted on a ¾ fine-grained sand and ½ organic ground substrate in a garden located in Kenya township in Luvua sublocation to test the rooting and growth of parts of tender and mature cuttings of the same variety of Passiflora quadrangularis L. in order to prepare viable rootstocks that are likely to yield better fruit. Methodology: The experiment on the propagation by cutting was conducted in two separate planter boxes. Subsequently, sowing of plants was done in 80cm x 80cm holes which were filled with 1/3 of chicken droppings and 2/3 of organic ground. The following are variables that were tested: the vigor of rooting, the height of leaves by three months, the diameter of the stem by six months, the height of leaves during flowering and days to maturity for fruits. Findings show a difference in the vigor of rooting: it was found to be higher in the Pq2BMA/18 cuttings than in the Pq1BT/18. The number of fruits did not show any significant difference despite the fact that Pq2BMA/18 cuttings yielded a higher number of fruits compared to those of Pq1BT/18. As regards the height of leaves by six months, the diameter of the stem by six months and the height of leaves during flowering, we postulated a null hypothesis and concluded that these variables did not show any significant difference.

Abstract: (french)
Objectif : Une étude a été réalisée sur un substrat ¾ du sable fin et ¼ de terreau dans un jardin situé à la commune Kenya, quartier Luvua ; pour tester la reprise et la croissance des portions de boutures tendres et de boutures matures aoutées d’une même variété de Passiflora quadrangularis L. pour préparer les porte-greffes viables donnant par la suite les meilleurs fruits. Méthodologie : l’essai de bouturage a été installé séparément dans deux jardinières. Puis suivi de la mise en place des plants dans les trous de 80cm x 80cm remplis de 1/3 de fiente et de 2/3 de terre organique. Voici les paramètres observés : La vigueur de la reprise, la taille de lianes à trois mois, le diamètre de la tige à six mois, la taille de lianes à la floraison et les jours de maturité des fruits. Les résultats indiquent qu’il existe une différence de vigueur, les boutures Pq2BMA/18 ont présenté une grande vigueur de reprise que celles Pq1BT/18. Le nombre des fruits ne relève pas une différence significative, bien que les boutures Pq2BMA/18 présentent un nombre élevé des fruits que les boutures Pq1BT/18. Concernant la taille de lianes à trois mois, le diamètre de la tige à six mois et la taille de lianes à la floraison, nous acceptons l’hypothèse nulle, à cet effet nous affirmons que la différence n’est pas significative.
