Bits of Sand Paper on Faba

Jun 10 9.30 am to 9.45 am

Shellacced with a good lot of shellac bits of sand paper which measured about 1.2 x 1.5 mm with the longer axis horizontal and (rough side surface inwards), so that the edge of the paper nearest the tip of the root is the edge at the dot at a measured distance from tip— Put in damp air in warm dark cupboard

[in margin:] Distance of card

Put in damp air in warm dark cupboard

Distance of card	Length of root at first	Examined at 7 pm	Examined Jan 11. 10 20 am
4)—	1— 35mm	0	1 0   grown ie aft 25 hr.
4)	2 . 23mm	—Very slight curve towards the card	2 bent nearly grown at rt angles and then partly straightened again, towards the card. Bend at the card
4)	3   14 mm	0	3 very faint bend towards grown
4)	4   34 mm	0	4 still fainter grown
3)	5   20mm	0	5 bent so [sketch] grown
3)	6 19mm	0	6   0   badly grown
3)	7   27 mm	0	7   0   badly grown
4)	8   ?	Very slight curve towards the card	8 bent so [sketch] grown
4)	9   ?	0	grown 9   0
4)	10   ?	0	grown 10   0

Result Two beans grew badly, so after abt 25 hrs only 2 out of 8 showed a bend I think they were too dry & none grew very well


The lengths of the tips were now

1 — 6mm	5 — 10.5mm	8 — 10m
2 — 8	6 — 4.5	9 — 8
3 — 9
4 — 9	7 3.5	10 — 6

Result Two beans grew badly, so after about 25 hrs only 2 out of 8 showed a bend

I think they were too dry & none grew very well

The lengths of the tips were now

now 1 ─ 6mm 2 ─ 8 3 ─ 9 4 ─ 9

mm 5 ─ 10.5 6 ─ 4.5 7 3.5

mm 8 ─ 10 9 ─ 8 10 ─ 6

Faba "cards" Damp air— Fixed with less shellac than before

15 Beans varying from 18 to 46 mm in length had cards sand paper stuck on at 3 & 4 mm from tip. After 12 1/2 11 hrs only one (No 3) showed any distinct effect, & was so:— [sketch], two others No 6 & 2 very slight bend towards no 3, 6, 2

When examined about 22 1/2 25 hrs from the beginning; No 2 had a sharp bend away; 3 had straightened: 5 slight bend away towards: 6 slight bend away: (all these have grown well) Nr 7, 8, 9 11, 12 had no bend & these had not grown properly. But 10 which has not bent grown well either has bent just at the card towards the card. 13 has a very slight bend towards & has grown well— Nrs 14 & 15 were not recorded unfortunately

Leaving out the 6 radicles that did not grow well, & nrs 14 & 15 as they were not recorded at the end—

There are only 7 roots & only one showed a distinct bend after 25 22 1/2 hrs. Or if one takes the first 12 1/2 hrs there are 9 roots. Of these 7 roots 6 had cards at 4 mm 1 got (No 13) which bent slightly had it at 3 mm

The one that bent (3), also 5 & 6 which showed faint bends towards & away, had card at 4 mm

No 10 which grew badly & yet bent towards card had it at 3 mm.

(Summary 15 radicles of which several did not grow well, after 11 hr 3/15 slightly bent to card: aft 22 1/2 hr 1/7 so bent; but 2 bent from card!! (over)
