The total number of reservists to be called up is 300,000, officials said.
The Russian leader's televised address to the nation released Wednesday came a day after Russian-controlled regions in eastern and southern Ukraine announced plans to hold votes on becoming integral parts of Russia. Putin's remarks also come against the backdrop of the U.N. General Assembly in New York at which Moscow was warned about its referendum plans.
The Kremlin-backed efforts to swallow up four regions could set the stage for Moscow to escalate the war following Ukrainian successes. The referendums, which have been expected to take place since the first months of the war, will start Friday in the Luhansk, Kherson and partly Russian-controlled Zaporizhzhia and Donetsk regions.
Putin accused the West in engaging in ``nuclear blackmail'' and noted ``statements of some high-ranking representatives of the leading NATO states about the possibility of using nuclear weapons of mass destruction against Russia.''
``To those who allow themselves such statements regarding Russia, I want to remind you that our country also has various means of destruction, and for separate components and more modern than those of NATO countries and when the territorial integrity of our country is threatened, to protect Russia and our people, we will certainly use all the means at our disposal,'' Putin said.
He added: ``It's not a bluff.''
Putin said he has signed a decree on the partial mobilization, which is due to start on Wednesday.
``We are talking about partial mobilization, that is, only citizens who are currently in the reserve will be subject to conscription, and above all, those who served in the armed forces have a certain military specialty and relevant experience,'' Putin said.
Russian Defense Minister Sergei Shoigu said in a televised interview Wednesday that only those with relevant combat and service experience will be mobilized.
Shoigu also said that 5,937 Russian soldiers have died in the Ukraine conflict, far lower than Western estimates that Russia has lost tens of thousands.
Putin said the decision to partially mobilize was ``fully adequate to the threats we face, namely to protect our homeland, its sovereignty and territorial integrity, to ensure the security of our people and people in the liberated territories.''
Earlier Wednesday, Ukrainian President Volodymyr Zelenskyy dismissed the referendum plans as ``noise'' and thanked Ukraine's allies for condemning the votes scheduled to start Friday.
In his nightly address Zelenskyy said there were lots of questions surrounding the announcements but stressed that they would not change Ukraine's commitment to retake areas occupied by Russian forces.
``The situation on the front line clearly indicates that the initiative belongs to Ukraine,'' he said. ``Our positions do not change because of the noise or any announcements somewhere. And we enjoy the full support of our partners in this.''
Even a partial mobilization is likely to increase dismay among Russians about the war. The Vesna opposition movement called for nationwide protests on Wednesday, saying ``Thousands of Russian men -- our fathers, brothers and husbands -- will be thrown into the meat grinder of the war. What will they be dying for? What will mothers and children be crying for?``
It was unclear how many would dare to protest amid Russia's overall suppression of opposition and harsh laws against discrediting soldiers and the military operation.
The upcoming referendum votes are all but certain to go Moscow's way. They were quickly dismissed as illegitimate by Western leaders who are backing Kyiv with military and other support that has helped its forces seize momentum on battlefields in the east and south.
``I thank all friends and partners of Ukraine for today's mass principled firm condemnation of Russia's attempts to stage new sham referenda,'' Zelenskyy said.
In another signal that Russia is digging in for a protracted and possibly ramped-up conflict, the Kremlin-controlled lower of house of parliament voted Tuesday to toughen laws against desertion, surrender and looting by Russian troops. Lawmakers also voted to introduce possible 10-year prison terms for soldiers refusing to fight.
If approved, as expected, by the upper house and then signed by Putin, the legislation would strengthen commanders' hands against failing morale reported among soldiers.
In the Russian-occupied city of Enerhodar, shelling continued around Europe's largest nuclear power plant. Ukrainian energy operator Energoatom said Russian shelling again damaged infrastructure at the Zaporizhzhia nuclear power plant and briefly forced workers to start two diesel generators for emergency power to the cooling pumps for one of the reactors.
Such pumps are essential for avoiding a meltdown at a nuclear facility even though all six of the plant's reactors have been shut down. Energoatom said the generators were later switched off as main power weas restored.
The Zaporizhzhia Nuclear Power Plant has been a focus for concern for months because of fears that shelling could lead to a radiation leak. Russia and Ukraine blame each other for the shelling.
