Effect of Seed Pretreatment Methods on Germination and Early Seedling Growth of Senna spectabilis

Table 3

Effect of the pretreatment methods on seedling mean height and diameter growth (cm) at 30 and 60 days after seed sowing.

Treatment	Treatment description	Mean height (cm) at 30 days	Mean height (cm) at 60 days	Mean diameter (mm) at 30 days	Mean diameter (mm)at 60 days
T1	Control (no pretreatment applied)	2.470^c	4.348^b	0.922^cd	1.603^abc
T2	Seeds soaked in cold water for 12 h	2.498^c	4.305^b	0.849^cd	1.525^bc
T3	Seeds soaked in cold water for 24 h	1.545^d	2.663^c	0.739^d	1.03^d
T4	Seeds soaked in cold water for 48 h	2.665^bc	4.585^b	0.986^c	1.468^c
T5	Seeds soaked in hot water for 12 h	3.075^abc	5.040^ab	1.002^bc	1.639^abc
T6	Seeds soaked in hot water for 24 h	3.215^abc	4.908^ab	1.176^ab	1.698^abc
T7	Seeds soaked in hot water for 48 h	3.375^ab	5.273^ab	1.171^ab	1.764^ab
T8	Nicked seeds	3.803^a	5.835^a	1.227^a	1.846^a
	value	<0.001	<0.001	<0.001	<0.001
	LSD0.05	0.536	0.536	0.417	0.536

Treatment means within each column followed by the same letters are not significantly different from each other at ; LSD_0.05, least significant differences of means (5% level).
