STORABILITY AND PRE-SOWING TREATMENTS OF AFRICAN STAR APPLE (CHRYSOPHYLLUM ALBIDUM G. Don) SEEDS

Abstract

Chrysophyllum albidum is a prominent, indigenous, economic fruit tree species found in compound farm agro-forestry systems . Investigation was conducted to overcome difficulty in germination and storability of C. albidum seeds in the forest nursery of Federal University of Agriculture, Abeokuta, Nigeria. The trial employed a 3x3 factorial experiment with three replications laid out in a completely randomized design to determine the effect of seed coat treatments including clipping at 2mm from distal, circumference and micropyle end; dipping in 10% sulphuric acid and no seed coat treatments and durations of seed storage 1, 5 and 9 days on the germination of C. albidum seeds. Pre-sowing and storage treatments significantly (p < 0.05) affected the germination of seeds. Percentage germination ranged from 17% to 61% for clipping to no seed coat treatment. Highest germination of 61% was recorded for seeds not pre-sowed. The percentage germination ranged from 16% to 60% for seeds stored for nine days to those stored for one day. Highest germination of 60% was recorded for seeds stored for one day. A significant (p < 0.05) decrease in percentage germination was recorded with increasing days of storage. The result of interaction effect revealed that highest germination of 86% was recorded for seeds stored for 5days without pre-sowing treatments. Storing of seeds for 5days is recommended for mass production of C. albidum seedlings in agro-forestry nursery.

Effects of Water Stress on Growth and Chlorophyll Contents of Ocimum gratissimum L. (Basil) [Lamiaceae]

“…The significant number of leaves recorded in VWO could be needed to give off excess water into the atmosphere as the plant has no place for storage of excess water. This agrees with the submissions of Adelani [21] and Dauda et al [22] who reported a significant number of leaves in Citrus tangelo, Abelmoschus esculentus, Chocorus olitorus, Telferia spp and Amaranthus spp watered daily. Also, various investigators [23][24][25][26][27][28] have reported the highest number of leaves in plants exposed to regular watering and decreased leaf number under water stress.…”

Improving Growth of Chrysophyllum albidum G. Don Seedlings Using Leaf Litters of Selected Nitrogen-Fixing Albizia Trees

“…It is called "Osan Agbalumo," "Udara" or "Udala" and "Agwaluma or Agwaluba" in Yoruba, Igbo and Hausa languages respectively (Rahaman, 2012;Wole, 2013;Adelani et al, 2018). The immense economical ; nutritional and medicinal , industrial (Olaoluwa et al, 2012) and ecological (Aduradola et al, 2005) values of C. albidum have been reported.…”
