Fruit and seed characteristics among selected Parkia biglobosa (JACQ) G. Don. Population

Abstract

Fruit Characteristics (pod length, number of pod per bunch, pulp and seed weight, pulp weight and pod breadth), Seed Characteristics (number of seed per bunch, expected seed number per pod and seed weight per bunch), and Qualitative Characteristics of seeds (seed colour, shape, size and texture) of Parkia biglobosa (Jacq) G. Don population were investigated in this study. Twenty six (26) P. biglobosa population were sampled at the permanent site of the University of Ilorin, Nigeria, in May 2010 and fruits were collected from these populations for study. Pulp and seeds were removed manually from the dry brown indehiscent pods by using hand to break the pods along their sutures and de-pulping was done by manual washing with hands in water. There were significant differences (at P=0.05) among the fruit and seed characteristics of 26 populations of P. biglobosa investigated. Five (5) plants showed high pod number per bunch with 20 pods and above while long pod lengths were observed in seventeen (17) plants. Two (2) plants have narrow pointed tip pods (apex) and four (4) plants with broad pod breadth. One (1) plant has its apex size similar to its base (1.53cm). Seventeen (17) plants were observed to have more than 100seeds per bunch while, only one plant was noticed to exhibit wrinkled seed coat, the fifteen (15) plants had flat oval seeds. Two (2) plants had pure black seed coat and twenty four (24) had brownish seed coat colours. Larger percent of the plants have medium seed size, five (5) plants have small seed size and others are of big size.

Germination and Seedling Development of Seeds from Different Parkia biglobosa (Jacq) G. Don Trees

“…This agrees with the observation of Hopkins (1983) and Olorunmaiye et al (2011). The seeds with brown seed coat germinated earlier than the dark-black, which suggests easier water penetration by the former and required no pretreatment of seeds.…”

Potentials of Aqueous Extract of Pod Husk Parkia biglobosa (Jacq.) Benth as a Biopesticide in Okra (Abelmoschus esculentus (L.) Moench) Production

“…This is in agreement with the report of Abagale et al [27], who discovered the presence of saponin, glycoside, flavonoids, tannin and polyphenols in P. biglobosa pod husk. Olorunmaiye et al [28] also reported the use of the pod husk in producing an insecticide powder or dust which is used in protecting crops from insect pests.…”

Evaluation of growth response of Parkia biglobosa (JACQ) under different levels of organic manures

“…There is no doubt that, one of the challenges of indigenous tree species regeneration is inadequate knowledge of the condition necessary for their germination and seedling production techniques (Sale, 2015;Mukhtar, 2016). P. biglobosais an important indigenous multipurpose tree species providing food, medicines and shade while stabilizing degraded environment and playing ecological role in nutrient cycling (Olorunmaiye et al, 2011;Adejumo et al, 2013;Oluwafemi et al, 2014). Information on growth and development of indigenous tree species is an important pre-requisite for sustainable utilization and regeneration of multipurpose tree species like P. biglobosa.…”
