1868) Mignonette. Black Thread Pollen from same plant.

The Pods grew to .2 or .25 of an inch in length & then all drop off─

I shd not be at all surprised if plants occasionally did produce Pods—

May 7' I have compared new [illeg] pollen of B. & A. size same, (dry) but B certainly very different colour.— The extra plant which I thought had yellow pollen, turns out a mistake. I think pollen of B less coherent.—

(I have been looking at 4 or 5 flowers, one with yellow pollen & from A & immature, & these had nearly half their anthers open & standing right over stigmas, but pollen so coherent had not dropped on: so self sterility may be partly due to stigmas not getting their own pollen without aid.)

(On Plant C. 10 flowers fertilised & produced 9 fine Pods

3 flowers on one branch produced moderately perfect pod, but one on one side & 2 of them not artificially fertilised) might have accidentally got dusted by adjoining plant─)

7 flowers fertilise crossed & all produced fine Pods & not one of self-fertilised flowers

F none crossed— did not produce any self-pods, except some at bottom, close above expanded flowers with open anthers which had been cut off when plant put under net— & I suppose that some pollen had got on stigmas, before these flower lower flowers with closed had opened their anthers — I may call this plant self-sterile

[22av]

Plant D 9 flower crossed & produced 7 fine Pods — on this Plant 2 pods for self, one beneath the crossed & one just above, hence I believe accidental — not one of the carefully artificially self-fertilised produced one pod.

 

May 14. Plant F (new) 31˚ ago I put plenty of pollen on stigmas & examined one & found abundance of tubes penetrating the stigmas. If this plant does not set seed this observation will suffice for I today fertilised with own pollen plenty of flowers.—

Plant A., 14 fl. fertilise by B (self-sterile) & C (I tried some by mixing pollen of 2 kinds produced 13 pods

16 by pollen of other flowers on same plant not one nor spontaneously any

Plant B — 14 flowers crossed by A, C D (self-sterile) & E — produce 14 pods, but produced some of them rather poor. 4 4 3 2 1

(⸮) 18 self-fertile by pollen ofotherflowers on same plant set none — but in a few 3 spont. produce were able to the artificially crossed flowers 3

Plant C, 10 flowers by pollen of A (self fertile) (B) (self-sterile) & D self-sterile & E ( ) produced 9 fine pods

19 flowers by pollen of distnct flower on same Plant, (set none?) (3) but again none crossed flowers (3)

D 10 fl crossed by A, B, C, & E, produced 9 fine pods

18 fl by pollen of distinct fl. on same plant. 0/ (only 2 spont. close to crossed.) (2)

E —5 7 fl by A, C. D & E & D, all produce fine pods

8 fl by pollen from distinct plant — none & none as spontaneously

F. produced none spontaneously & many flowers were artificially self-fertilised & produce none (Pollen-tubes)

July 2d /68/ an additional mignonette Plant. (I think making 6th) or 7th??) has been long placed under net quite by itself & has not set seed of any kind—

Sept. 3 /68/ Four additional plants were placed altogether under net— some of them produced pods on part of stems in most capricious manner; hence I believe some Bee or Fly got in. —
