Can "poor" subdomains have negative impact on root domain PR?

Can "poor" subdomains have negative impact on root domain PR?

My company implemented a way of showing clients progress on their websites. We do this by implementing "development" subdomains (example - development20.oursite.com).

My question is, since Google is indexing these subdomains, does the fact that they are not necessarily credible have negative impact on our root domain?

We noticed a PR drop from 6 to 4 over the past year and this came to my mind but wasn't sure how subdomains affected the root domain.

Any thoughts are appreciated!

you shouldn't let google index content on development servers.
i would implement one of the following (in order of preference) methods of robots exclusion:
- use basic HTTP authentication for that subdomain, which will serve a 401 Authorization Required status code to search engine crawlers.
- include a noindex meta robots tag or X-Robots-Tag header in your HTTP response.
- disallow crawling the development content using robots.txt
