Sahhalini nulg
Sahhalini nulg (Abies sachalinensis) on männiliste sugukonda nulu perekonda kuuluv igihaljas okaspuu. Ta on väga lähedane sugulane jaapani nuluga (Abies veitchii).
Sahhalini nulu avastas eurooplaste jaoks 1866 saksa botaanik Carl Friedrich Schmidt (1811–1890) Sahhalinil, kuid ta ei toonud sellest taimest näidiseid Euroopasse. 1877 avastas taime teisena inglise taimekoguja Charles Marles Jaapanis Honshū saarel Aomori lähedal, pidades seda esmalt jaapani nulu teisendiks.[3]
Sisukord
Teisendid[muuda | muuda lähteteksti]
Sahhalini nulul eristatakse nelja teisendit:[2]
- Sahhalini nulg (Abies sachalinensis var. sachalinensis) ehk põhiteisend kasvab Sahhalinil, Kuriili saartel (Iturupil, Kunaširil ja Šikotanil) ning Jaapani saartel (Hokkaidol, Rebunil, Rishiril ja Okushiril).
- Mayri nulg (Abies sachalinensis var. mayriana Miyabe & Kudô) on Sahhalini nuluga väga sarnane ja nad kasvavad tihti ka koos. Erandiks on Sahhalini saar, kus Mayri nulu levila on üksnes saare lõunaosas.
- Wilsoni nulg (Abies sachalinensis var. nemorensis Mayr) kasvab peamiselt Sahhalini saarel koos Sahhalini nuluga, vähesel määral ka Hokkaidol.
- Kamtšatka nulg (Abies sachalinensis var. gracilis (Kom.) Farjon) kasvab vaid ligi 20 hektari suurusel maa-alal Kamtšatka poolsaarel ja selle kaugus Sahhalini saarest on ligi 1100 km.
Kirjeldus[muuda | muuda lähteteksti]
Sahhalini nulg sarnaneb jaapani ja siberi nuluga ning võib elada 180–200, harva kuni 250 aasta vanuseks.[4]
Puu kasvab tavaliselt 25–2.

Below is an extract from a web page. Evaluate whether the page has a high educational
value and could be useful in an educational setting for teaching from primary school to
grade school levels using the additive 5-point scoring system described below. Points are
accumulated based on the satisfaction of each criterion:
- Add 1 point if the extract provides some basic information relevant to educational top-
ics, even if it includes some irrelevant or non-academic content like advertisements and
promotional material.
- Add another point if the extract addresses certain elements pertinent to education but
does not align closely with educational standards. It might mix educational content with
non-educational material, offering a superficial overview of potentially useful topics, or
presenting information in a disorganized manner and incoherent writing style.
- Award a third point if the extract is appropriate for educational use and introduces key
concepts relevant to school curricula. It is coherent though it may not be comprehensive
or could include some extraneous information. It may resemble an introductory section of
a textbook or a basic tutorial that is suitable for learning but has notable limitations like
treating concepts that are too complex for grade school students.
- Grant a fourth point if the extract highly relevant and beneficial for educational purposes
for a level not higher than grade school, exhibiting a clear and consistent writing style. It
could be similar to a chapter from a textbook or a tutorial, offering substantial educational
content, including exercises and solutions, with minimal irrelevant information, and the
concepts aren’t too advanced for grade school students. The content is coherent, focused,
and valuable for structured learning.
- Bestow a fifth point if the extract is outstanding in its educational value, perfectly suited for
teaching either at primary school or grade school. It follows detailed reasoning, the writing
style is easy to follow and offers profound and thorough insights into the subject matter,
devoid of any non-educational or complex content.

The extract provides basic information about the Sahhalini fir, including its classification, discovery, and variations. It introduces key concepts relevant to botany and is coherent, although it may not be comprehensive. The content is focused and valuable for structured learning, but the writing style is not particularly engaging for primary or grade school students. 

Educational score: 4
