Dear Prof

Let’s consider the short text below related to botany:

At the end of the study, we obtained a rate of 91 p.c.of vegetative recovery for the cuttings (1) ... shade and (2) … 97 p.c. for the cuttings exposed to the sun. However, the cuttings (3) … plots exposed to the sun clearly stand out from the cuttings (4) … the shade with a shorter time of recovery. (5) … 3 months, only the (6) … (7) … despite a high recovery rate for all the cuttings.

A. Can ‘per cent’ be abbreviated as ‘p.c.’ or is it better to write ‘%’?

B. Which option is correct to complete each blank above?
1. in / in the / under / under the
2. of / Ø
3. of / from
4. in / under
5. After / At the end of
6. sunny seedlings / seedlings exposed to the sun
7. survive / survived / have survived

Thank you
Léopold

Here's how I think the text should read. While 'p.c.' is occasionally used for 'percent', this usually indicates that the user has a mobile device where the percentage symbol is not easily available.

At the end of the study, we obtained a vegetative recovery rate of 91% for the cuttings in the shade and 97% for the cuttings exposed to the sun. However, the cuttings from plots exposed to the sun clearly stand out from the cuttings taken from the shade with their shorter time of recovery. After three months, only the seedlings exposed to the sun survived, despite a high recovery rate for all the cuttings.

The corrections are relatively straightforward - but note I have also made other changes. You are 'in the shade' when you are under something shady. If you are writing the article in the third month the present perfect should be used. Otherwise, this is an event in the past and the past tense is required. Unless the seedlings emit sunlight, they should not be called 'sunny seedlings'.
