Differences in mobility of calcium applied to the aboveground parts of broad bean plants (Vicia faba L.)

Figures & data

Table 1 Distribution of 45Ca applied to different parts of the broad bean plant

		Area of application of ^45Ca
		Leaf (surface)	Leaf (reverse)	Pod	Stem
Lower nodes	Leaves	0.01	0.01	0.02	0.05
	Stem	0.00	0.01	0.12	0.23
	Pod wall	0.00b	0.01b	0.07ab	0.11a
	Seeds	0.00	0.00	0.00	0.01
Applied nodes	Leaves	99.95a	99.86a	1.09c	11.13b
	Stem	0.00	0.00	2.59	19.00
	Pod wall	0.01c	0.00c	85.32a	29.39b
	Seeds	0.00b	0.00b	8.43a	2.43b
Upper nodes	Leaves	0.01	0.02	0.84	29.60
	Stem	0.01	0.06	1.03	4.02
	Pod wall	0.00b	0.00b	0.06ab	0.15a
	Seeds	0.00	0.00	0.01	0.01
Newly developed nodes		0.01	0.01	0.41	3.86
Each value is a percentage of the activity of the part to that of the sum of all parts. Values followed by letters significantly differ at the 5% level using least significant differences.

Table 2 Distribution of 45Ca applied to two different positions on the stem of the broad bean plant

		Area of application of ^45Ca
		Axillary side	Opposite side
Lower nodes	Leaves	0.06	0.03
	Stem	0.03	0.02
	Pod wall	0.07	0.05
	Seeds	0.03	0.02
Applied nodes	Leaves	4.05	4.63
	Stem	38.08	25.92
	Pod wall	37.07*	4.39
	Seeds	9.20	0.70
Upper nodes	Leaves	2.68	10.43*
	Stem	3.44	8.43
	Pod wall	0.57	16.03*
	Seeds	0.06	3.59
Newly developed nodes		4.65	25.78
Each value is a percentage of the activity of the part to that of the sum of all parts. Values followed by * are significantly larger at the 5% level using a t-test.
