Germination

Hydro-priming is an important seed treatment technique for rapid seed germination. Cola species exhibits long and uneven germination. Hence this study was aimed at investigating the effect of hydro-priming durations on the germination and seedling growth of Cola parchycarpa and Cola rostrata. Five treatments (hydro-priming durations of 0 hour, 24 hours, 48 hours, 72 hours and 96 hours) were used and the experiment was laid out in a completely randomized design (CRD) with 6 replicates each. In C.

The major problem in Cola propagation is related to seed germination and slow growth rate, hence this study was designed to ascertain the effect of soil types and mechanical scarification on the germination and seedling growth of Cola nitida. The experiment was a two factored experiment of 4 soil type (Topsoil, topsoil combined with carbonized sawdust (TSCSD), topsoil combined with river soil (TSRS) and River soil) and 2 scarification (Nicked and Whole seed) laid in a Completely Randomized Design (CRD) with 3 replicates.

In the present study, seeds of Pigeon pea (Cajanus cajan L. Millspaugh) accessions (Brown and Cream colours) were treated with different concentrations of Ethyl methane sulphonate (0.0 %, 0.01 %, 0.02 %, 0.03 %, 0.04 %, 0.05 %, 0.06 % and 0.07 %). The seeds were sown and monitored for 30 days. Data obtained showed a trendy effect. Data obtained showed that germination percentage was decreased with an increase in the mutagen concentration when compared with the control.
